Application Note 030

Certified reference materials for analysis of VOCs in air by thermal desorption (TD)–GC

Application Note 030

In environmental analytical chemistry, the analyst usually preconcentrates the contaminants extracted from a sample matrix, which can be water, waste, soil or gas.

Bias in a method is typically estimated by analysing a representative or control sample of the matrix loaded with known amounts of the contaminant. Estimating bias is uniquely difficult if the matrix is workplace or ambient air.

This note relates to the use of reference materials for the analysis of VOCs in air by thermal desorption (TD)–GC.
