Grab Sample Measurements
The analyzer can also be used for measurement of TOC, TC, and IC directly
from sample bottles. In the Grab Sample mode, specify how many replicate
measurements to make from a sample bottle and how many of these
measurements are to be used in the calculation of average values and
standard deviation or coefficient of variation (relative standard deviation).
WARNING
Make sure the DI Reservoir is full, particularly when running samples with high
TOC’s or high salt concentrations. If there is an air bubble in the reservoir,
high levels of salts may contaminate the reservoir and deplete the resin. Always
“clean-up” the analyzer by running low TOC DI water (at least three
measurements) after running high TOC or salt samples.
If using the analyzer for on-line measurements, change the sample mode in
the SETUP menu to GRAB SAMPLING and change the sample inlet plumbing.
If running both on-line and grab samples, consider using the sample switching
