Abstract
The utility model discloses a formaldehyde fast detecting instrument, comprising a bottom cylinder for drug storing. A column-shaped cylinder for drug storing is arranged on the bottom cylinder. Alkali liquor and solid chromogenic agent are respectively arranged in the bottom cylinder for drug storing and the column-shaped cylinder for drug storing. When detecting, the button is pressed and the chromogenic agent in the column-shaped cylinder for drug storing is pressed into the bottom cylinder for drug storing to mix with the alkali liquor. Detecting board clipped with test paper is inserted into the bottom cylinder for drug storing, and the test paper is soaked thoroughly. The soaked test paper is exposed in the air, and the color of the test paper is changed by the reaction generated by the chromogenic agent on the test paper. The concentration of the formaldehyde in the detected air can be determined by the contrast with a contrasting color card. The utility model has the advantages of high speed, simpleness, high sensitivity and simple detecting procedure, and the formaldehyde fast detecting instrument is suitable for the use of common consumer.
Description
Technical field
The utility model is a kind of rapid detection apparatus, particularly a kind of utensil that is used for disposable analyzing and testing air content of formaldehyde.
Background technology
Formaldehyde, (HCHO), specific gravity of gas 1.067, liquid specific gravity 0.815, fusing point-92 ℃, the aqueous solution of boiling point-19.5 ℃ common 40% is commonly called as formalin.Formaldehyde is commonly used for agricultural chemicals, antiseptic and sanitizer, also is used to make phenolics, pollopas, polyvinyl, dyestuff and building materials etc.If but excessive use can cause that content of formaldehyde exceeds standard in the air, harm that can be serious to healthy generation.
How raising along with people are familiar with the pay attention to day by day and the PARA FORMALDEHYDE PRILLS(91,95) of health detects formaldehyde and is taken precautions against and more and more paid close attention to by everybody.The conventional method of measuring content of formaldehyde in the air is generally used large-scale instrument at present, and its advantage is highly sensitive, quantitatively accurate.But also there is the step complexity, needs defective such as professional and technical personnel's operation, mensuration expense height and be difficult for universal.Along with developing rapidly of domestic real estate and the decoration of thing followed household, it is imperative to develop a kind of formaldehyde detection meter simple to operate, that the result is reliable and cheap rapidly, that be suitable for the use of common people family.
Chinese patent CN2616903Y discloses a kind of formaldehyde and has detected meter, its essence is that the medicine head (similar cotton swab) that will dip in sodium bisulfite is by contacting measured object to obtain a result.But the method have its part unilateral, can not more complete reaction test environment situation, particularly can't measure defectives such as airborne formaldehyde amount.One of inventor once on April 15th, 2004 and on May 13rd, 2004 application number be respectively in 200410017701.2 and 200410018305.1 the patented claim, " formaldehyde repid test test paper in the air " and " formaldehyde repid test reagent bottle in the air " successively proposed.Adopt 4-amido-3 Ping base-5 mercapto 1,2,4-triazole (AHMT) and potassium hydroxide (KOH) and potassium metaperiodate (KIO
4) solution is mixed into developer.But be applied to concrete testing product as detecting principle, still not having at present.
The utility model content
The purpose of this utility model is to provide a kind of energy formaldehyde fast and convenient, that be suitable for ordinary consumer oneself detection to detect meter.
To achieve these goals, formaldehyde detection meter of the present utility model adopts following technical scheme: place formaldehyde to detect in the meter respectively solid developer and alkali lye, the preceding mixing to be used.Again this mixed liquor is soaked into test paper, is exposed in the air by moistening test paper again, produce reaction by the developer on the test paper color of test paper is changed, again by with the concentration of formaldehyde of relatively judging tested air of contrast colour atla.
According to above-mentioned feature, the utility model adopts following structure: comprise a storing the bottom tube of medicine, end tube loam cake one middle cover; In cover and be connected with a column cartridge, can store developer in the column cartridge and a stage clip is arranged, stage clip and developer press in the column cartridge by a loam cake and button; In the appropriate location of middle cover one notch is set, this notch can hold one group of check-out console to be passed through.
During detection, the developer that presses the button the solid shape in the column cartridge is pressed in the storing the bottom tube of medicine, with alkaline reaction wherein.To accompany the notch insertion storing the bottom tube of medicine of the check-out console of test paper then by middle cover, test paper is soaked into, be exposed in the air by moistening test paper again, produce reaction by the developer on the test paper color of test paper changed, again by with the concentration of formaldehyde of relatively judging tested air of contrast colour atla.
Compare prior art, the utility model formaldehyde fast detecting meter can simply reflect airborne content of formaldehyde fast, highly sensitive, it is few to detect step, and is suitable for the content of formaldehyde that ordinary consumer is used in aspects such as oneself's detection furniture, house decoration, inner space.Owing to adopted the Separation of Solid and Liquid structure, developer and alkali lye in the formaldehyde fast detecting meter are preserved for a long time simultaneously.
