The time of whole experiment has been saved to this device cost that has significantly reduced, realizes the high sensitivity of whole device, high detection limit, the utility model discloses can use in quick examination survey pesticide residue's field.
Description
Technical field
The utility model relates to chemical analysis process tower technical field, particularly relates to a kind of pesticide residue detection device.
Background technology
Purify to detect food, agricultural product drug residue and banned substance in down-stream better to the remains of pesticide extracted from food, carry out the inner adsorption stuffing composition of various decontaminating columns that this purification adopts at present simple, as only having C18, C8, NH2, CN, Si, Al or organic polymer etc., this adsorption stuffing is suitable for a kind of or alanysis thing absorption, be not suitable for polycomponent process, therefore the decontaminating column processing time of prior art is long, be of limited application, cost is higher.
Chinese patent: application number 03261139, discloses a kind of residual decontaminating column of agriculture and purification method thereof that mixed fillers is housed.Decontaminating column of the present invention comprises shell, upper sieve plate, lower sieve plate and filler, described upper sieve plate is positioned at decontaminating column housing interior volume comparatively top, lower sieve plate is positioned at decontaminating column outer casing bottom, filler, between described upper and lower sieve plate, is characterized in that, described filler is made up of (percentage by weight) following component: activated charcoal 1%-30%, zeyssatite 40%-80%, filtration aid 15%-45%, above-mentioned filler mixed packing, particle size range is between 5 μm-100 μm.Also the having that sensitivity is not high, detection limit is not high, use the problem that adsorption rate that is inconvenient and that filter is not high of this invention.
Summary of the invention
The purpose of this utility model is for above deficiency, provide a kind of highly sensitive, detect limit for height, the pesticide residue detection device that easy to use and adsorption rate is high.
To achieve these goals, the utility model have employed following technical scheme:
A kind of pesticide residue detection device, comprise shell, hydrophilic sieve plate, filler and hydrophobic sieve plate, hydrophilic sieve plate, filler and hydrophobic sieve plate are from top to bottom established in the enclosure successively, it is characterized in that: also comprise demarcation strip; Filler is separately formed multiple filtering layer by described demarcation strip.
Above-described filler includes zeyssatite, zeolite molecular sieve, activated charcoal and activated alumina, and zeyssatite, zeolite molecular sieve, activated charcoal and activated alumina are separated with demarcation strip successively and establish in the enclosure.
The thickness of above-described demarcation strip, hydrophobic sieve plate and hydrophilic sieve plate is 1.5mm.
Above-described zeyssatite, zeolite molecular sieve, activated charcoal and activated alumina particle size range are 100 μm-120 μm.
Above-described shell is U-shaped.
The beneficial effects of the utility model:
The utility model adopts hydrophilic sieve plate to be separated by each filler, make can change separately when certain filler will be changed, also can require according to the difference of user the number of plies reducing or increase filler, the utility model can make test solution rapid permeability in each filler simultaneously, allow each filler give full play to the effect of carrying residues of pesticides, play the effect of test solution purification.This device greatly reduces cost, saves the time of whole experiment, realizes the high sensitivity of whole device, high detection limit, and the utility model can measure in the field of residues of pesticides at rapid screening and use.
