6 Sample the background for one minute and note the TIC count.
7 Hold the probe over the sample of interest for up to 1 minute. If the TIC count
begins to rise, slowly back the probe away from the sample. If the TIC count
does not rise after a full minute, move the probe away from the sample.
7a A peak may appear if the compound present is greater than 1 ppm. A
compound identification may also be present on the HAPSITE screen.
NOTE: No response may indicate either the compound present is less than the
detection limit, or that no detectable compound is present.
