16.5.3 Contamination of the Probe and Probe Line
Contamination of the Probe and Probe Line can occur when the Probe Tip actually
touches a sample or a compound "sticks" in the Probe Line.
16.5.3.1 Symptoms
Symptoms of contamination in the probe and probe line include a high continuous
base line with the same or similar identification in Survey Mode. It can also be seen
as a persistent peak in Analyze (GC/MS) Mode.
16.5.3.2 Decontaminate
1 Remove the probe from the HAPSITE.
2 Hold the probe and probe line in a "U" shape.
3 Holding the probe, pour methanol from a squeeze bottle into the probe nut until
methanol is visually seen coming out of the probe line through the LEMO
connector.
WARNING
For safety precautions, wear appropriate PPE according
to the manufacturer’s MSDS. See
