Toner total volatile organic compounds (TVOC), benzene and Determination of styrene - Thermal desorption - gas chromatography

1 Scope

This standard specifies the method of determination of TVOC, benzene and styrene content in the toner by thermal desorption - gas chromatography. This method is suitable for the determination of TVOC, benzene and styrene in toner.

2 principle

The thermal desorption tube filled with the toner sample is directly heated on a thermal desorber, and the volatile organic compounds in the sample enter with an inert carrier gas Cryogenic trap, the trap quickly heated to high temperatures, gasification of organic matter with the carrier gas into the gas chromatographic detection analysis, with a standard method of quantification Calculate.
