摘要：

该研究旨在建立基于顶空进样-气相色谱/质谱联用技术（HS-GC-MS）的清洁剂中15种挥发性有机化合物（VOCs）的检测方法。通过系统优化顶空进样参数、色谱分离条件及质谱检测模式，开发出涵盖三氯甲烷、苯系物和卤代烃等多类型VOCs的快速检测方法。创新性地采用模拟基质加标法消除基质干扰，并构建双色谱柱（Rxi-5Sil MS与DB-624）交叉验证体系以增强定性可靠性。方法学验证显示：线性范围为1~500 μg/mL时，各化合物相关系数（R2）均大于0.999；方法检出限（LOD）介于0.02~0.14 μg/mL；加标回收率为82.8%~116.0%，精密度相对标准偏差（RSD）均小于5%。实际样品检测发现，市售清洁剂中三氯甲烷和甲苯检出率最高，三氯甲烷最大含量达0.53 μg/mL。

Abstract:

This study aims to establish a detection method for 15 volatile organic compounds （VOCs） in cleaning agents based on headspace injection - gas chromatography/mass spectrometry （HS-GC-MS）. The multi-response surface method was adopted to simultaneously refine three key analytical dimensions: headspace equilibrium thermodynamics, chromatographic elution trajectory, and mass spectrometry acquisition parameters. Developed rapid detection methods covering multiple types of VOCs such as chloroform, benzene series and halogenated hydrocarbons. Innovatively, the simulated matrix labeling method was adopted to eliminate matrix interference, and a dual chromatographic columns （Rxi-5Sil MS and DB-624） cross-verification system was constructed to enhance qualitative reliability. Methodological validation shows that when the linear range is 1-500 μg/mL, the correlation coefficients （R2） of each compound are all better than 0.999. The method detection limit （LOD） ranges from 0.02 to 0.14 μg/mL. The recovery rates of spiked products are 82.8%-116.0%, and the relative standard deviations （RSDs） of intraday precision are all better than 5%. Actual sample testing reveals that the detection rates of trichloromethane and toluene are the highest among commercially available cleaning agents, with the maximum content of trichloromethane reaching 0.53 μg/mL.
