Operator’s Manual Chapter 5: Maintaining the Mercury Analyzer Replace the Tygon ® drain waste as described on page 59. Sample in and drain tubes need to be replaced monthly. If needed, a cell gas tubing kit is available from CETAC with the correct labeled tubing included, pre-cut to the correct length. NOTE: Do not use waste tubing other than that provided by CETAC. The interior diameter and length (3 feet) of the drain tube are optimized for maximum system stability, and should not be altered. Other tubes are similarly optimized and substitutions/alterations should not be made. 114
CETAC QuickTrace M-7600 Mercury Analyzer Chapter 5: Maintaining the Mercury Analyzer Retubing the Gas-Liquid Separator This procedure should be followed once a month, unless the samples are excessively “dirty,” in which case the procedure should be followed more often, as needed. Improper installation can damage the GLS, so it is recommended to read the entire procedure before beginning. This procedure shows the drain tubing being installed after the GLS is mounted on the instrument. Alternatively, the capillary, liquid mix tube, and drain tube can be installed prior to the GLS being installed in its mount. GLS Inlet Refer to Figure 5-11. Note tubing routing and then remove all tubing, drain sleeve (J), inlet capillary (C) and silicone sleeve (D) from the GLS using the same procedure as for Viton ® tubing above.

Carefully direct the capillary end of the insert into the top protruding end of the silicone tube (D), and GENTLY push straight down. The capillary insert (C) should go down inside the inlet guide (E). Continue pushing gently downward until the exposed capillary end (C) protrudes below 115
