2.3.1Guidelines for Measuring and Cutting the Suction Line

The vinyl line contains a very low parts-per-million level of phenols. If phenol content affects your sample analysis, use the PTFE suction line.

When installing the sampler, be sure the vertical distance between the liquid level and the pump is as small as possible.

Cut the line to the desired length but use the shortest length feasible for the installation.

Cut the line in 1 foot increments. For instance, 4 feet, not 31/2. If using metric units of measure, cut the line in increments of 0.1 meter. Do not include the length of the strainer in the measurement.

2.3.2Attaching Suction Line Attach the vinyl suction line to the pump tube with the 3/8-inch

to Pump Tube

tubing coupler. First, screw the threaded end into the suction line

 

until the flat surface is flush against the suction line

 

(Figure 2-5). Then, push the other end of the coupler into the end

 

of the pump tube until the other flat surface is flush against the

 

tubing.

Once the coupler is attached to the pump tube, removal is dif- ficult, and may require cutting the tube.
