  4. 6890 FLAME PHOTOMETRIC DETECTOR Flame Photometric Product No. : G2333A/G2334A or HP 6890 option 240/241 Single and Dual Signal options. EPC Only. Same design as the 5890 FPD . (Most part numbers the same) Phosphorus and Sulfur filters available. Agilent Restricted

  5. 6890 FLAME PHOTOMETRIC DETECTOR Installation: Can be retrofitted on older instruments but may require top cover modification. PMT mounted left to right Single FPD - Fitted in back position (ease of access to front) Dual FPD - Fitted in back : Uses both detector PCB slots : Cannot use ALS in back position. Uses both DETB and AUX2 heated zones to heat transfer line and heated block, but only DET temp entered. Requires AUX actuator solenoid bracket and wiring harness. Requires 2.1x 6890 firmware and 4.02 Chemstation (single) 3.0x 6890 firmware and 5.01 Chemstation (dual) Agilent Restricted
