I need to analyze the levels of benzene and xylene in the air, with concentrations ranging from 0 to 10%. I would like to know if there are any simple instruments (other than chromatographs) that can be used for this purpose

For benzene derivatives, chromatographic analysis is both fast and accurate (both gas chromatography and liquid chromatography can be used), and there are many types of columns available for this purpose, offering good selectivity. Currently, domestic chromatographs can be purchased for around 20,000 to 30,000 yuan, and they provide satisfactory precision. If there are other methods as well, I’ll learn them too

Chromatography is great, but since I only need to use it for a while, it would be a waste to go and buy one right away
