CHNS analysis of glass fiber filters loaded with particulate matter

When collecting particulate matter in natural waters or in the air for the analysis of carbon, hydrogen, nitrogen, and sulfur (CHNS), glass or quartz fiber filters are used. For CHNS determination, these filters are combusted using an elemental analyzer.

We offer a special instrument package which is optimized for the CHNS analysis of filters up to 47 mm. This Application Note demonstrates the analysis of filters with our instrument package especially designed for this application.
