3 Installation Manual for SRS 300 Gas Assisted Regeneration Kit Page 3 of 7 SECTION 1 - INTRODUCTION This guide describes the Installation of the SRS 300 Gas Assisted Regeneration Kit (P/N ) for use with the Self- Regenerating Suppressor (SRS) 300. This device can be operated in Gas Assisted Recycle Mode and Gas Assisted External Water Mode. SECTION 2 - INSTALLATION IN THE SRS RECYCLE MODE 2.1 Installation Steps a. Connect the 1/8" REGEN IN line (Shortest tubing extending from the Tee) to the SRS REGEN IN port. b. Connect the line from the Mixing Tee (longer tubing extending from the Tee) to the back pressure coils. c. Start flow through the columns and suppressor (with the current on) until eluent exits the REGEN OUT port. d. Connect a gas line to the Regulator. e. Pressurize the Regulator between 5-15 psi using either Helium or Nitrogen gas. NOTE: The gas flow across the Regenerant chamber in a 4-mm SRS 300 is approximately 100 cc (ml/min) at a set pressure of psi. The gas flow across the Regenerant chamber in a 2-mm SRS 300 is approximately 100 cc (ml/min) at a set pressure of psi.

Connect the 1/8" REGEN IN line (Shortest tubing extending from the Tee) to the SRS REGEN IN port. b. Connect the line from the Mixing Tee (the longer tubing extending from the Tee) to the line from the external water source. A pump capable of delivering 2-3 ml/min is recommended for operation in the external water mode. c. Start flow through the columns and suppressor (with the current on) until water exits the REGEN OUT port. d. Connect a gas line to the Regulator. e. Pressurize the Regulator between 5-15 psi using either Helium or Nitrogen gas. NOTE: The gas flow across the Regenerant chamber in a 4-mm SRS 300 is approximately 100 ml/min at a set pressure of psi. The gas flow across the Regenerant chamber in a 2-mm SRS 300 is approximately 100 ml/min at a set pressure of psi.

Place the gas assisted apparatus directly before the REGEN IN port of the SRS 300 allowing normal operation with additional detectors.

This mode of operation replaces the external water mode of operation that uses 5-10 cc (ml/min) of deionized water. 5.2 External Water Mode For solvent applications, Gas Assisted Regeneration in the External Water mode using a pump is recommended. The recommended deionized water flow is approximately 2-3 ml/min for most applications. This replaces the external water mode of operation that uses ml/min of deionized water. SECTION 6 - OPERATION A mixture of gas and liquid will be seen in the short tubing near the REGEN IN port. The gas and liquid should be finely mixed under the above conditions. Due to the high gas velocity, only a trace of liquid should be visible in the waste line. If discrete zones of gas followed by liquid (similar to normal SRS 300 operation) are observed in the waste line, check for high back pressure in the waste line. Replace the waste line if constriction or back pressure is observed. The waste line should be a 1/8" line that is free from bends and constrictions. The recommended SRS 300 Back Pressure Coils should remain in place after the Conductivity Cell. SECTION 7 - SOLVENT CONSIDERATIONS When operating with eluents containing solvents, the regenerant chamber may develop higher back pressure. Under this condition, increase the gas pressure to achieve higher gas flow rate to allow for complete mixing of gas and liquid.

AC2 Power Control Accessory P/N CAM Controlled Air Module, 115V P/N The AC2 module controls the CAM module, turning the gas ON and OFF. 8.2 DX 120 Systems The following items are recommended for operation with DX 120 systems to automatically turn ON and OFF the flow of gas. CAM Controlled Air Module, 115 V P/N Accessory Power Adapter Cable P/N The cable connects the CAM directly to the AC output on the back of the DX 120, which is activated through a solid state relay. 8.3 Gas Requirements It is important to turn off the suppressor current when the analytical pump is off; otherwise, the presence of gas flow will cause a high voltage alarm and in some instances will damage the suppressor device. In order to reduce gas waste, turn off the gas flow when the system is not operational. WARNING: Nitrogen, helium or argon gases are recommended for the above application. Compressed air is not recommended for the above application due to potential contamination. When using in-house generated gases, suitable traps to remove moisture, hydrocarbons, carbon dioxide and other particulate matter are recommended.
