YN-CLVI Pesticide Residue Analyzer
Organophosphate and carbamate pesticide is currently the largest use of pesticides,and more is on the prohibition of the use in fruit,vegetable.This class of pesticides with acetylcholinesterase(Ache)binding in vivo,and are not easily seperated,namely ache activity is inhibited,resulting in the hydrolysis of acetylcholine can’t accumulate in nerve conduction,nerve hyperexcitablity symptoms of poisoning and even death.Based on this toxic principle produces enzyme inhibition rate method, the detection principle can be simply expressed as follows: using a sensitive enzyme extract source prepared butyrylcholinesterase as a detection reagent, according to the degree of change in the activity of butyrylcholinesterase fruits and Vegetables samples to determine pesticide residues.
YN-CLVI is the only one instrument which can test heavy metal(Chromium, cadmium, mercury, arsenic and lead) in fruits,vegetabls,food etc.

Digestion furnace & Waste gas collector for Heavy metal analysis
Digestion furnace is mainly used for digestion treatment before chemical analysis of samples such as plant, seed, fodder, food, soil mineral in sectors including agriculture forestry, environmental protection, geology, petroleum, chemical industry and food, and it can also match nitrogen determination apparatus or be used as COD.
1. Heating body (module) is precisely cast and processed by aluminum alloy or graphite, resisting acid and alkali and long service life.
2. Furnace hole temperature can be continuously adjustable, fast rate of temperature increase and broad range of application
3. Small temperature difference between holes, great sample digestion consistency, high thermal efficiency, beneficial to sample digestion.
4. Instrument table-board and test tube stand are welded by brushed stainless steel plate, certainly corrosion resistant.
5. Adopted new generation LCD temperature-controlled instrument has functions of timed shutdown and alarming. PID intelligent control technology is high temperature control precision, small temperature rise range and easy to learn, and can achieve temperature programming.

Waste gas collector
During sample digestion,there is lots of acid mist produced,it will pollute environment and harmful for operator healthy,so,it needs a waste gas collector to collect acid mist produced and exhaust to sewage.
