2.9 Sample Collection Modes
The Sample Loop is used to detect chemicals in the low ppm to high ppb
concentration range. Concentrator tubes are used to detect chemicals in the low
ppb to high ppt concentration range. The following procedures are used to install
and remove the Sample Loop and Concentrator tubes.
2.9.1 Installing the Sample Loop
The Sample Loop is a hollow stainless steel tube. The sample volume is
approximately 200 µL. Black insulation covers the center of the Sample Loop and
each end has a nut and ferrule assembly. See Figure 2-37.
NOTE: The HAPSITE is originally shipped with the Sample Loop in place.
