Gas chromatographic mass spectrometric techniques using methane chemical ionization have been employed to characterize the chemical composition of Toxaphene reference material, as well as the metabolized residue in milk fat resulting from controlled administration to cows. The results indicated that selection of particular ions can be of great value in determining whether or not an observed residue by electron capture should be attributed to a metabolized residue of Toxaphene. Analysis of six commercial milk samples by electron capture gas chromatography and gas chromatography mass spectrometry/chemical ionization/selected ion monitoring has provided semi-quantitative data for comparison of the determinative step.
采用甲烷化学电离的气相色谱-质谱技术已用于表征毒杀芬标准物质的化学成分，以及给奶牛控制性投药后乳脂中产生的代谢残留物。结果表明，选择特定离子对于确定通过电子捕获观察到的残留物是否应归因于毒杀芬的代谢残留物具有重要价值。通过电子捕获气相色谱和气相色谱-质谱/化学电离/选择离子监测对六个商业牛奶样品进行分析，为比较测定步骤提供了半定量数据。
