Description
本創作揭示一種比色管置具。This creation discloses a colorimetric tube set.
所謂比色管置具(英語：a cuvette’s holder)是一種分析光的強度的裝置或機構，此裝置搭配光度計可以量測不同波長光的強度，分析波長與光強度的關係的光偵測器是經由感測體吸收光能而轉換成電子訊號，藉此量測光通量或是光功率。The so-called color tube set (English: a cuvette's holder) is a device or mechanism for analyzing the intensity of light. This device can measure the intensity of light of different wavelengths with a photometer, and analyze the relationship between wavelength and light intensity. It is converted into an electronic signal by absorbing light energy through the sensing body, thereby measuring the luminous flux or the optical power.
如第1圖為一種由多個管壁所建構的比色管置具1之外觀圖示，且該比色管置具1用以裝載：一光發射器11(以發光二極體(LED)為例)，配置於一第一管壁內，且該光發射器11之一發光外緣曝露於該第一管壁；一光接收器13(以光電二極體(Photo Diode)為例)，配置於一第二管壁內，且該光接收器之一接光外緣曝露於該第二管壁；以及一待測樣品12(以葉綠素濃度溶液為例)，裝載在一比色管16內且該比色管16置於連接於該第一管壁及第二管壁之間的一第三管壁之上。需了解的，光發射器11之一發光孔徑與光接收器之一接光孔徑呈一平行狀態。FIG. 1 is an external view of a colorimetric tube set 1 constructed by a plurality of tube walls, and the colorimetric tube set 1 is used for loading: a light emitter 11 (with a light emitting diode (LED) As an example, disposed in a first tube wall, and one of the light emitters 11 is exposed to the first tube wall; an optical receiver 13 (taking a photodiode) Is disposed in a second tube wall, and one of the light receivers is exposed to the second tube wall; and a sample to be tested 12 (for example, a chlorophyll concentration solution) is loaded in a colorimetric color The tube 16 is disposed above the third tube wall between the first tube wall and the second tube wall. It should be understood that the light emitting aperture of one of the light emitters 11 is in a parallel state with the light receiving aperture of one of the light receivers.
如要知曉待測樣品(例如葉綠素濃度溶液)12之光吸收程度時：將光發射器11所發出的單色光(如藍光)通過待測樣品(葉綠素濃度溶液)12，並以測定待測樣品(葉綠素濃度溶液)12對藍光光波的吸光度，接著，光接收器13將依據未被葉綠素吸光的光強度轉換成光電流，因而研究人員可使用光度計之分析軟體後，能依據光電流的數值大小繪出吸收光譜。此外，利用特定波長的單色光分別透過標準溶液與待測溶液，比較其吸光度，可作定量分析。To know the degree of light absorption of the sample to be tested (eg, chlorophyll concentration solution) 12: pass monochromatic light (such as blue light) emitted by the light emitter 11 through the sample to be tested (chlorophyll concentration solution) 12, and determine the test to be tested. The absorbance of the sample (chlorophyll concentration solution) 12 to the blue light wave, and then, the light receiver 13 converts the light intensity that is not absorbed by the chlorophyll into a photocurrent, so that the researcher can use the photometer to analyze the software and then according to the photocurrent The numerical size plots the absorption spectrum. In addition, the monochromatic light of a specific wavelength is respectively transmitted through the standard solution and the solution to be tested, and the absorbance is compared, which can be quantitatively analyzed.
故，以目前比色管置具的優點為：製作簡單，成本低廉，可以隔絕除頂端開孔外之外在環境的光線干擾。Therefore, the advantages of the current colorimetric tube are: simple fabrication, low cost, and can isolate light interference in the environment except for the top opening.
相較之下，以缺點而論：LED光束非平行光，其散射光會經管壁多次散射後，進入接收器端，造成干擾。接收器端的開孔過大，容易接受到散射光，另外，上端無遮罩，外界光線會經由上端開孔進入，造成干擾。In contrast, in terms of shortcomings: LED beams are non-parallel, and their scattered light is scattered multiple times through the tube wall and enters the receiver, causing interference. The opening of the receiver end is too large, and it is easy to receive the scattered light. In addition, there is no mask at the upper end, and external light enters through the upper opening, causing interference.
承上所述，因光源散射的緣故導致雜訊的產生，這會使影響光電流訊號的數值大小，造成量測的誤差過大。According to the above, the generation of noise due to the scattering of the light source causes the magnitude of the photocurrent signal to be affected, and the measurement error is too large.
再者，當比色管置具運用在量測螢光技術時，同樣地，也因光源散射的緣故導致光電流背景值過大，而無法量測到螢光強度。Furthermore, when the colorimetric tube device is used in the measurement fluorescence technique, similarly, the background value of the photocurrent is too large due to the scattering of the light source, and the fluorescence intensity cannot be measured.
[註]：表格一為描述測定待測樣品：例如：葉綠素濃度之光吸收部分及螢光吸收部分的光電流背景值大小。[Note]: Table 1 describes the measurement of the sample to be tested: for example, the light absorption background of the chlorophyll concentration and the background value of the photocurrent of the fluorescent absorption portion.
本創作提出一種比色管置具，在用途優勢方面：用以解決習知因光源散射的緣故導致雜訊的產生，因此，暗室中量測，排除60Hz電子雜訊干擾，光電流背景值可以控制在0.01uA以下，這會使得依據光電流-訊號的數值大小所繪出吸收光譜有精確的數據結果。This creation proposes a colorimetric tube set, which is used to solve the conventional noise caused by the scattering of the light source. Therefore, the measurement in the dark room eliminates the interference of 60 Hz electronic noise, and the background value of the photocurrent can be Controlled below 0.01uA, this results in accurate data results for the absorption spectrum based on the magnitude of the photocurrent-signal.
為滿足上述之目的，本創作所提出的一種比色管置具，為多個管壁所建構，且該比色管置具用於裝載：一光發射器，配置於一第一管壁內，且該光發射器之一發光外緣未曝露於該第一管壁；一光接收器，配置於一第二管壁內，且該光接收器之一接光外緣未曝露於該第二管壁；以及一待測樣品，裝載在一比色管內且該比色管配置於連接於該第一管壁及第二管壁之間的一第三管壁之上，其中當該光發射器發出的一單色光通過該待測樣品時，藉由與該光發射器呈一平行狀態的該光接收器測定該待測 樣品對該單色光光波的吸光度。In order to meet the above objectives, a colorimetric tube set proposed by the present invention is constructed for a plurality of tube walls, and the colorimetric tube device is used for loading: a light emitter disposed in a first tube wall And the light emitting outer edge of the light emitter is not exposed to the first tube wall; a light receiver is disposed in a second tube wall, and one of the light receivers is not exposed to the light edge a tube wall; and a sample to be tested, loaded in a colorimetric tube, and the colorimetric tube is disposed on a third tube wall connected between the first tube wall and the second tube wall, wherein When a monochromatic light emitted by the light emitter passes through the sample to be tested, the light receiver is determined to be in a parallel state with the light emitter.

考慮習知比色管置具1：(1)有無遮罩的問題，(2)所裝載光發射器11、光接收器13及一設置於光發射器11與光接收器13之間的待測樣品12中三個元件之間相對位置關係，(3)入射與接收光源的角度及位置，及(4)分析光吸收部分及螢光吸收部分所測量光電流的大小。Considering the conventional colorimetric tube set 1: (1) the problem of masking, (2) the loaded light emitter 11, the light receiver 13, and a standby between the light emitter 11 and the light receiver 13 The relative positional relationship between the three components in the sample 12 is measured, (3) the angle and position of the incident and receiving light sources, and (4) the magnitude of the photocurrent measured by the light absorbing portion and the fluorescent absorbing portion.
首先，為解決上述習知比色管置具1之(1)上端無遮罩，外界光線會經由上端開孔進入，造成干擾。如第2圖所示，該圖為本創作之比色管置具2之實體設計觀圖。由多個管壁(W1~W6)所建構的比色管置具2呈一立方體態樣(亦指一密閉空間)，且該些管壁(W1~W6)為一不透明材料所製成，其中管壁W1、W2及W5中設有相對應的孔洞以供一光發射器21、一光接收器23及一螢光接收器24(示於第5圖中)***。First, in order to solve the above-mentioned conventional colorimetric tube set 1 (1), the upper end is unmasked, and external light enters through the upper end opening, causing interference. As shown in Fig. 2, the figure is a physical design view of the colorimetric tube set 2 of the present invention. The colorimetric tube device 2 constructed by a plurality of tube walls (W1 to W6) has a cubic shape (also referred to as a confined space), and the tube walls (W1 to W6) are made of an opaque material. Corresponding holes are provided in the pipe walls W1, W2 and W5 for insertion by a light emitter 21, a light receiver 23 and a fluorescent receiver 24 (shown in Fig. 5).
以下的段落將描述本案之比色管置具2所裝載光發射器21、光接收器23及一設置於光發射器21與光接收器23之間的待測樣品22中三個元件之間(2)相對位置關係(3)入射光源與接收光源的角度及位置(4)分析光吸收部分及螢光吸收部分所測量光電流的大小。The following paragraphs will describe the light emitter 21 loaded in the colorimetric tube set 2 of the present invention, the light receiver 23, and a three of the elements 22 to be tested disposed between the light emitter 21 and the light receiver 23. (2) Relative positional relationship (3) Angle and position of the incident light source and the receiving light source (4) The magnitude of the photocurrent measured by the light absorbing portion and the fluorescent absorbing portion is analyzed.
其中，如第3圖所示，該圖為本創作之比色管置具2之平面設計觀圖。該比色管置具2所裝載：光發射器21(以發光二極體(LED)為例)，配置於第一管壁W1內，且該光發射器21之一發光外緣未曝露於該第一管壁W1。光接收器23(以光電二極體(Photo Diode)為例)，配置於第二管壁W2內，且該光接收器23之一接光外緣未曝露於該第二管壁W2。待測樣品22(以葉綠素濃度溶液為例)，裝載在一比色管26內且該比色管26配置於連接 於該第一管壁W1及第二管壁W2之間的第三管壁W3之上。需了解的，光發射器21之一發光孔徑d1與光接收器23之一接光孔徑d2呈一平行狀態。Among them, as shown in Fig. 3, the figure is a plan view of the colorimetric tube set 2 of the present invention. The colorimetric tube device 2 is mounted on the light emitter 21 (taking a light emitting diode (LED) as an example), disposed in the first tube wall W1, and one of the light emitters 21 is not exposed to the light emitting outer edge. The first tube wall W1. The photoreceiver 23 (for example, a photodiode) is disposed in the second tube wall W2, and one of the light receiving members 23 is not exposed to the second tube wall W2. The sample to be tested 22 (taking a chlorophyll concentration solution as an example) is loaded in a colorimetric tube 26 and the colorimetric tube 26 is disposed in the connection. Above the third tube wall W3 between the first tube wall W1 and the second tube wall W2. It should be understood that one of the light-emitting apertures d1 of the light emitter 21 and the light-receiving aperture d2 of the light receiver 23 are in a parallel state.
其次，對於比色管置具2之外觀設計的其他參數關係式為：該光接收器23之一接光孔徑d2/第一管壁W1與第二管壁W2之間距D為小於tan10°。該光發射器21之一發光孔徑d1不大於(亦指小於等於)該光發射器21之直徑D21/2(註：“/”為除號，下同)。Next, the other parameter relationship for the design of the colorimetric tube set 2 is that the light receiving aperture d2 / the distance between the first tube wall W1 and the second tube wall W2 is less than tan 10 °. The light-emitting aperture d1 of one of the light emitters 21 is not greater than (also referred to as less than or equal to) the diameter D21/2 of the light emitter 21 (note: "/" is a division number, the same applies hereinafter).
最後，當習知比色管置1具運用在量測螢光技術時，因光源散射的緣故導致光電流背景值過大，而無法量測到螢光強度的問題。本案的解決的方案為：如第4圖所示，該圖為本創作之比色管置具2之裝載螢光接收器24的配置圖。從圖中可知，螢光接收器24配置於第五管壁W5而與該單色光呈一垂直狀態及該螢光接收器24之一接光外緣未曝露於該第五管壁W5。且螢光接收器24之一接光孔徑d3/該螢光接收器24與該單色光相隔的一垂直距離L為小於tan20°。Finally, when the conventional colorimetric tube is used in the measurement fluorescence technique, the background value of the photocurrent is too large due to the scattering of the light source, and the problem of the fluorescence intensity cannot be measured. The solution to the present solution is as shown in FIG. 4, which is a configuration diagram of the loading fluorescent receiver 24 of the colorimetric tube set 2 of the present invention. As can be seen from the figure, the fluorescent receiver 24 is disposed on the fifth tube wall W5 and is perpendicular to the monochromatic light, and the light receiving outer edge of the fluorescent receiver 24 is not exposed to the fifth tube wall W5. And one of the fluorescent receivers 24 is connected to the optical aperture d3/the vertical distance L between the fluorescent receiver 24 and the monochromatic light is less than tan20.
還需一提的，如第5圖為供應一光度計所需電源之外觀圖示。故，該光發射器21與該螢光接收器24之正負電極兩端透過一外罩盒27所形成暗室之一孔洞而與一印刷電路板25外接。It should also be mentioned that, as shown in Figure 5, the appearance of the power supply required for a photometer is shown. Therefore, the light emitter 21 and the positive and negative electrodes of the fluorescent receiver 24 are externally connected to a printed circuit board 25 through a hole formed in a shadow chamber formed by a cover case 27.
承上所述，當研究人員使用上述之本創作之比色管置具2而要知曉待測樣品(例如葉綠素濃度溶液)22之光吸收程度時：將特定發光二極體21所發出的單色光(如藍光)通過待測樣品(葉綠素濃度溶液)22，並以測定溶液對藍光光波的吸光度，接著光接收器(例如光電二極體)23將依據未被葉綠素吸光的光強度轉換成光電流，因而研究人員可使用光度計之分析軟體之後，才能依據光電流的數值大小繪出吸收光譜。此外，利用特定波長的單色光分別透過標準溶液與待測溶液，比較其吸光度，可作定量分析。As described above, when the researcher uses the colorimetric tube set 2 described above to know the degree of light absorption of the sample to be tested (for example, the chlorophyll concentration solution) 22, the single light-emitting diode 21 is issued. The color light (such as blue light) passes through the sample to be tested (chlorophyll concentration solution) 22, and absorbs the absorbance of the blue light wave by the solution, and then the light receiver (for example, photodiode) 23 converts the light intensity according to the light absorption without chlorophyll into Photocurrent, so researchers can use the analysis software of the photometer to plot the absorption spectrum based on the magnitude of the photocurrent. In addition, the monochromatic light of a specific wavelength is respectively transmitted through the standard solution and the solution to be tested, and the absorbance is compared, which can be quantitatively analyzed.
[註]：表格二及表格三為描述測定待測樣品：例如：葉綠素濃度之光吸收部分及螢光吸收部分的光電流背景值大小。[Note]: Table 2 and Table 3 are for describing the sample to be tested: for example, the photocurrent background of the chlorophyll concentration and the background value of the photocurrent of the fluorescent absorption portion.
[結論]：相較於習知比色管置具未能在暗室中量測及因光源散射的緣故導致雜訊的產生，這兩者因素會使得如葉綠素此類型的待測樣品測得的光電流有較大的數值。在克服先前兩者因素之下，依據本創作之新型構件的比色管置之外觀設計可在暗室中量測，排除60Hz電子雜訊干擾，且在集中光源之優勢下，光電流背景值可以控制在0.01uA以下，研究人員依據該光電流數值所繪出吸收光譜才有精確的數據結果。[Conclusion]: Compared with the conventional colorimetric tube device, it can not measure in the dark room and cause the noise due to the scattering of the light source. These two factors will make the sample of the sample such as chlorophyll measured. The photocurrent has a large value. Under the previous two factors, the design of the colorimetric tube according to the novel component of the present invention can be measured in the darkroom, eliminating 60 Hz electronic noise interference, and under the advantage of the concentrated light source, the photocurrent background value can be The control is below 0.01uA, and the researchers have accurate data results based on the absorption current spectrum.
