The reduction of analysis times in analytical chemistry is an essential factor to ensure high laboratory productivity and cost efficiency. This is especially important when considering substances such as pesticides. Their widespread use requires increasingly frequent monitoring of food, water, air, and soil to ensure consumer safety and monitor environmental contamination [1]. This work combines two techniques typically used separately to achieve faster gas-chromatographic analyses: Low-Pressure Gas Chromatography (LPGC) and hydrogen (H2) as carrier gas. The combination of these approaches resulted in a significant reduction in analysis times while maintaining good levels of resolution and sensitivity [2, 3, 4].
