Operations/Analysis Unit 4

A zero may be established with a reproducible simulated (offset) zero absorbance fluid in the sample cell of the analyzer. When possible this fluid should be stable for H2O content and should approximate the process being measured to minimize the offset zeroing, otherwise, dry air or nitrogen can be used. The analyzer must first be calibrated for sensitivity full scale by using known certified/analyzed samples containing the component (analyte(s) to be measured.

NOTES:

These samples (low/mid/high about 1 liter each) must be prepared and provided for introduction into the zero and/or span port of the sample system, with outlet collected from the cal return port of the sample system. A 500 to l liter glass syringe with Luor-loc to 1/4" tube connections should be used for introducing the samples into the analyzer sample cell for zero and span cal adjustments. These are introduced through the calibration ports usually labelled zero or span fluid inlets. The exiting samples when nontoxic are usually collected in waste containers from the cal-return port of the instrument cabinet. These cannot be used again as water vapor from containers and atmosphere will contaminate them. They would require analysis again before reintroducing for correlation purposes. Also, its is a good practice to flush copiously the sampling train with each calibration sample prior to accepting any read value. Each sample should be allowed to stabilize before reading. When a N2 flush is used to dry the sampling train before each sample is read, the readings will come to equilibrium faster since no water cross-contamination should be evident or occur.

11IF CALIBRATION PROCESS REPRESENTATIVE SAMPLES CANNOT BE OBTAINED,

THEN A DIRECT ON-LINE TWO-POINT CALIBRATION APPROACH CAN BE USED AS FOLLOWS:

Assuming customer has designed in a sampling valve (this valve may contain a chromatographic septum port for a needle, i.e., for toxic or flammable samples at low pressure), hookup for a sampling bomb (high pressure), grab sample port, or sealed container to draw off representative process grab samples. Note: All samples are brought to the analytical lab for speedy analyses (preferably analyzed within 15 minutes) to correlate to process conditions. The sample analyzed should be by an analytical method with an acceptable precision and accuracy as used to normally monitor the process and confirm the on-line analysis. The on-line analyzer is only as accurate
