2.4 Positioning a Sampler
• Place the sampler on a flat horizontal
surface. The refrigerator has leveling feet
that can be adjusted to keep the
refrigerator level.
• Be sure the vertical distance between the
liquid and the pump is as small as
possible.
• Route the line so that it runs
continuously downhill from the sampler
to the liquid source. This helps drain the
line during presample and postsample
purges.
• Avoid loops of coiled suction line.
• For representative samples, place the
intake in the main current of the flow
stream, not in an eddy, or at the edge of
flow.
