6.1 Practical notes on ion chromatography Maintenance An unstable baseline (pulsation and flow rate fluctuations) is attributable to contaminated valves or defective, leaking piston seals in many cases. Contaminated valves are cleaned by rinsing with water, RBS solution or acetone (see Section 6.2.5). When the cleaned valves are reinstalled, you must ensure that the flow direction is correct. The procedure for replacement of piston seals is described in Section 6.2.5.
6 Notes – Maintenance – Faults The suppressor module must never be switched in dry state as there is a danger of blocking. Maintenance In the event of reduced capacity or high counter-pressure, the suppressor module must be regenerated (Section 6.2.6), cleaned (Section 6.2.7) or exchanged (Section 6.2.8). 6.1.6 Connections All connections between injector, column and detector must be as short as possible, have a low dead volume and must be absolutely tight.
6.2 Maintenance and servicing 6.2 Maintenance and servicing 6.2.1 General information Care The 761 SD Compact IC requires proper care and attention. Excessive contamination of the instrument could possibly lead to malfunctions and a shorter service life of the inherently rugged mechanical and electronic parts. For protection against escaping fluids, the two drain tubes for the inner compartment and for the bottle rack must be fitted (see Section 2.5).
6 Notes – Maintenance – Faults rinsed free of salt with methanol/water (1:4) to avoid crystallisation of eluent salts with the corresponding subsequent damage. The connections to the separating column and suppressor module must be removed for rinsing. The two capillaries 35 and 37 (see Figure 3) must be directly connected together using a coupling 54 (6.2744.040). Rinse with methanol/water (1:4) until the conductivity drops below 10 µS/cm. 6.2.
