The detection of some chlordane compounds (heptachlor, cis‐/trans‐chlordane and cis‐/trans‐nonachlor) by positive ion chemical ionization (PICI) in an ion trap was studied using acetonitrile, acrylonitrile and dichloromethane as non‐conventional reagent gases. These reagent gases initiated specific fragmentation reactions and resulted in different response factors. All reagent gases enabled detection limits in the low‐pg range for heptachlor, whereas the detection limits of cis‐/trans‐chlordane and cis‐/trans‐nonachlor were in the mid‐pg range. Additionally, the acetonitrile and dichloromethane PICI mass spectra of the cis‐ and trans‐stereoisomers of chlordane and nonachlor were different. Copyright © 2001 John Wiley & Sons, Ltd.
