Pesticides standards

[evik]

I am trying to set up the method for organophosphorus and organonitrogen pesticides in vegetables and fruits (by using GC-NPD), but I need to buy some standards. Could you give me some suggestions on where I could find standards for this kind of analysis?

Thanx in advance!

Just about any supplier of GC consumables will offer a line of standards. There are a number of companies that do nothing but sell standards. If I were to list several, thre would be a large number of companies that I would overlook. A quick internet search for "Pesticide Standards" and "Pesticide analytical standards" shows some vendors that I recognize amoung the first hits listed.

I would suggest that you start with your favorite laboratory suppliers, look in the trade magazines you recieve and look at websites for trade shows (like PittCon) for potential vendors.

evik,

One of the best suppliers I have found for pesticide standards is ChemService. But, as Don notes, Restek, Supelco, Ultra Scientific, AccuStandard, to name just a few ....

Best regards.
