or water contamination of the sample will cause a major dysfunction,
so the sample needs to be maintained above its dew point at all
times - a perfect application for TRACEPAK.
Gas Chromatography typically use a
single small diameter tube, 6mm or 1/4" seamless stainless
steel or Teflon, with an electric tracer capable of maintaining
60°C/140°F at various ambient conditions, such as O'Brien's
It is also common to have a multiple
tube bundle for gas chromatography. An additional tube is often
used to return the unused sample back to the process. Return lines
for gas chromatography usually only require freeze protection.
