Combusting filters

There was some discussion at the AMS14 conference about the best way to handle samples collected on filters. These samples can be difficult because the filters can be too large to easily fit into a 6 mm tube, and also because researchers often use glass fiber filters which can melt during combustion causing failure of the quartz combustion tube.

Paula Zermeno consulted with researchers from WHOI and CAMS and summarized the general recommendations for handling these samples.
