Replacing The Chemical Reagents - GE Sievers 900 Series Operation And Maintenance Manual

Replacing the Chemical Reagents

The oxidizer and acid reagents must be purchased from GE Analytical Instruments to ensure
product purity and operating life. The use of reagents from other sources or failure to replace the
reagents on the prescribed replacement schedule will invalidate the Analyzer's warranty.
Reagent containers are for single-use only: do not refill. Refilling or reusing
reagent containers will void all Analyzer and parts warranties and nullify any
performance claims.
To avoid exposure to the chemical reagents, wear acid-resistant gloves, protective
clothing, and safety goggles or a face shield when changing the reagent supplies.
1. If the Analyzer is taking measurements, press the Stop Analysis button.
2. Turn off power to the Analyzer with the main power switch.
3. Open the Analyzer front panel by turning the two latches and swinging the panel door to
the left.
4. Locate the reagent enclosure, located at the top left-hand side of the Analyzer as you face
the Analyzer. Loosen the set screw and remove the reagent enclosure cover.
5. For each cartridge that you are replacing:
• Remove the cartridge from the enclosure.
• Push the red button to close the valve.
• Loosen the PEEK nut and disconnect the cartridge from the reagent syringe tubing.
Acid or oxidizer may spill from the containers if the valves are not closed.
Note: Reagent containers need to be disposed of according to local regulations. All reagent
containers are shipped with Material Safety Data Sheets (MSDS). These sheets will
provide instructions. GE Analytical Instruments can not accept containers for disposal.
