Analysis of Simazine and Thiobencarb by GC-MS method using hydrogen carrier gas
MSTips No. 401
Helium (He), which is widely used as a carrier gas for GC, may face problems such as temporary price increases or unstable supply conditions due to various reasons, and when supply delays occur, it is necessary to consider using another type of carrier gas as an alternative. Hydrogen and nitrogen are the main alternative gases being considered. Hydrogen, in particular, has a wide linear velocity range for optimum separation and is suitable as a carrier gas for GC. In this report, simazine and thiobencarb, pesticides subject to environmental standards for water pollution, were measured with hydrogen carrier gas. The results show good linearity of the calibration curve and reproducibility at the lower limit of quantification.
