Organic Phosphorus Pesticide Mixture Standard Solutions

Organophosphorus pesticides are widely used mainly as insecticides. Organophosphorus pesticides inhibit the action of cholinesterase and makes it difficult to decompose acetylcholine, which is a neurotransmitter, which causes impaired neurotransmission. Since organophosphorus pesticides are highly toxic to the human, their use is being reduced worldwide.
FUJIFILM Wako provide 4 types of organic phosphorus pesticide mixed standard solutions as FA series. 56 compounds of organophosphorus pesticides can be analyzed simultaneously.
