  • Page 47: Uncrating And Inspecting The Analyzer

    Uncrating and Inspecting the Analyzer The analyzer and its associated sample system is shipped pre-mounted on a backpan, either alone in a crate or in a crated weatherproof shelter. Upon receiving the analyzer system, remove the shipping crates and check the exterior of the shelter and/or analyzer for damage. Open the shelter and verify its internal components are secure and there is no phys- ical damage.

    (breaker) must be connected to and mounted near the ana- lyzer, in an easily accessible area. The switch (breaker) must be clearly labeled (e.g., “AMETEK Model 933 Analyzer Main AC Power Discon- nect Switch”). For safety reasons during maintenance, this switch allows the main AC power to be disconnected from the analyzer prior to performing service on the analyzer.

    The first UV-absorbing gas species that elute through the chromato- graphic columns are hydrogen sulfide (H S), carbonyl sulfide (COS), and methyl mercaptan (MeSH). Because the Model 933 Analyzer can measure the concentrations of all three of these species, COS and MeSH do not interfere with the H S measurement.
