Abstract
Many walls carbon nanotube solid -phase extraction pillar, including void column pipe, upper screen deck, lower sieve, many walls carbon nanotube packing layer, the intraductal from the bottom up of void column installs down sieve, many walls carbon nanotube packing layer, upper screen deck in proper order, and many walls carbon nanotube packing layer passes through upper screen deck, the lower sieve plate voltage is tightly intraductal at the void column. Many walls carbon nanotube solid -phase extraction pillar is high to carbamates pesticide adsorption rate, and the selectivity is good, and with the high performance liquid chromatography - tandem mass spectrum carbamates pesticide residue in the analysis tea -seed oil that combines together, it is simple to have the method, and the sensitivity is reliable, advantages such as low cost to be applicable to the analysis and the detection of the compound in the various fields such as food analysis, environmental analysis, chemical analysis.
Description
Technical field
The present invention relates to a kind of detect carbamate pesticide residue device, be specially a kind of multi-walled carbon nano-tubes solid phase extraction column detecting carbamate pesticide residue in tea oil.
Background technology
The detection method of carbamate pesticide residue amount mainly contains biochemical assay and chromatographic detection, chromatographic detection mainly contains vapor-phase chromatography, liquid phase chromatography, GC-MS(gas chromatography-mass spectrography) (GC-MS), Liquid Chromatography-Mass Spectrometry etc., the pre-treatment of these methods generally adopts gel permeation chromatography, the steps such as commercialization solid phase extraction column purification, because the component concentration residual to be measured in tea oil is few, matrix is complicated, interference impurity is many, so this type of sample complexity of existing pre-treating method process is loaded down with trivial details, abstraction and purification difficulty, testing result error is large, accuracy rate is not high.And need to consume a large amount of organic reagents or pre-treatment consumptive material costly, be inconvenient to apply.
Summary of the invention
In order to solve the problem, devise a kind of multi-walled carbon nano-tubes solid phase extraction column, the technical scheme of employing is as follows:
Multi-walled carbon nano-tubes solid phase extraction column, comprise void column pipe, upper sieve plate, lower sieve plate, multi-walled carbon nano-tubes packing layer, be provided with lower sieve plate, multi-walled carbon nano-tubes packing layer, upper sieve plate from top to bottom successively in void column pipe, multi-walled carbon nano-tubes packing layer is pressed in void column pipe by upper sieve plate, lower sieve plate.
Further, the multi-walled carbon nano-tubes external diameter in multi-walled carbon nano-tubes packing layer is 10-30nm, and length is 0.5-30 μm.
Further, the multi-walled carbon nano-tubes external diameter in multi-walled carbon nano-tubes packing layer is 10-20nm, and length is 10-30 μm.
Preferred as one, the thickness of multi-walled carbon nano-tubes packing layer is 0.2-0.4cm.
The utility model has following effect: multi-walled carbon nano-tubes solid phase extraction column is good to carbamate chemicals for agriculture specificity, adsorption rate is high, selectivity is good, combine with high performance liquid chromatography-tandem mass and analyze carbamate pesticide residue in tea oil, there is method simple, sensitive, reliably, the advantage such as with low cost, and be applicable to analysis and the detection of the compound in the various fields such as food analysis, environmental analysis, chemical analysis.
