Bleed Comparison Between Natural and Red PTFE Sample Using Gas Chromatography
Intuitively, one would surmise that pigmented materials (i.e. those that are coloured in some way) would be more likely to pose as a contaminant source when compared to materials that are not pigmented. This study compares two (2) 0.1 mm thick samples of PTFE. One is red in colour and the other is non-pigmented or natural. The Total Peak Area illustrates that the Natural (non-pigmented) PTFE shows a value of (0) zero, while the Red PTFE yielded a total peak area of 315. Using lower bleed materials provides truer readings, eliminates another potential error source, decreases sample contamination, and improves productivity.
