3.1 Handling the suppressor 3 Operation 3.1 Handling the suppressor General The Metrohm Suppressor Module MSM for chemical suppression installed in the suppressor block consists of a total of 3 suppressor units which are in turn used for suppression, regenerated with sulfuric acid and rinsed with water. In order to record each new chromatogram under comparable conditions a freshly regenerated suppressor unit is normally used.
3 Operation 3.2 Manual operation The 753 Suppressor Module cannot be manually operated unless the installation has been carried out properly as described in section 2 (mains connection, attaching the pump tubing, connection to the IC system). Switch instrument on/off The 753 Suppressor Module is switched on and off using mains switch 13 on the rear of the instrument (see Fig.
3.3 Operation via 690 Ion Chromatograph 3.3 Operation via 690 Ion Chromatograph The 753 Suppressor Module cannot be remotely operated via the 690 Ion Chromatograph unless the installation has been carried out properly as described in section 2 (mains connection, connection cable 690 – 753, attaching the pump tubing, connection to the IC system). When operating the 753 Suppressor Module together with the 690 Ion Chromatograph the pump on the suppressor module must still be switched on and off manually.
3 Operation 3.4 Operation via 732 IC Detector The 753 Suppressor Module cannot be remotely operated via the 732 IC Detector unless the installation has been carried out properly as described in section 2 (mains connection, connection cable 732 – 753, attaching the pump tubing, connection to the IC system).
3.4 Operation via 732 IC Detector Switch pump on/off in a program In the 732 IC Detector the key can be used to create time programs with a maximum of 20 program steps (see section 4.7.1 of 732/733 Manual). The pump can be switched on or off at any program step by setting the remote output lead 1 to 1 (on, active, 0 V) or 0 (off, inactive, open) respectively: Switch on: Switch off: >PROGRAM/edit remote XXX.X min 1TTTTTTT >PROGRAM/edit remote XXX.
3 Operation Rotate: Reset output lead: >PROGRAM/edit remote XXX.X min T1TTTTTT >PROGRAM/edit remote XXX.X min T0TTTTTT Example Automatically changing the suppressor position in "inject"programs (for manual operation or with autosamplers). PROGRAM progr.type: 0.0 remote 0.1 remote inject T1TTTTTT T0TTTTTT Rotate suppressor at an event In the 732 IC Detector the key can be used to program a maximum of 4 different events (see section 4.7.3 of 732/733 Manual ).
4.1 Malfunctions and their rectification 4 Malfunctions – Maintenance 4.1 Malfunctions and their rectification If difficulties appear with the IC system during analysis, their cause are best investigated in the order separating column → pump → eluent → IC system. An overview of possible malfunctions, their causes and remedies can be found in the instruction manuals of both 690 Ion Chromatograph (section 6.5) and 732/733 IC System (section 5.3.2).
4 Malfunctions – Maintenance Suppressor moves to next position but display lamp 7 no longer lights up • Suppressor dry • Rinse all 3 suppressor units with solution for at least 10 min. • Suppressor temporarily in the wrong position • Switch instrument off and then on again. Switch off suppressor remote operation with key 6 and operate key 8 . Check whether display lamp 7 lights up. Repeat this procedure 2-3 times; wait at least 10 s each time before the key is operated.
4.2 Maintenance and servicing 4.2 Maintenance and servicing 4.2.1 Care The 753 Suppressor Module 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. Spilled chemicals and solvents should be wiped up immediately. It is especially important to protect the plug connections at the rear of the instrument (particular the mains plug) against contamination.
4 Malfunctions – Maintenance 4.2.4 Exchanging the pump tubing Pump tubings are consumable material with a limited lifetime and should be exchanged at regular intervals (approx. every 2 weeks under continuous use). The working life of pump tubing depends to a considerable extent on the contact pressure. This is why the contact pressure must be correctly set as described in section 2.3.2 or 2.4.2 respectively.
4.2 Maintenance and servicing 4.2.5 Regeneration of the suppressor If the suppressor units are exposed to certain heavy metals (e.g. iron) or organic contaminants for longer periods of time then these can no longer be removed completely by the regeneration solution normally used (20 mmol/L H2SO4). This diminishes the capacity of the suppressor units which in milder cases results in a reduced sensitivity to phosphates and in severe cases in a strong increase in the baseline.
4 Malfunctions – Maintenance 4.2.6 Cleaning the suppressor Cleaning the suppressor may be necessary in the following cases (see also section 4.1): • Blockage of the suppressor which cannot be remedied (the suppressor can no longer deliver solutions) • Obstruction of the suppressor which cannot be remedied (the suppressor can no longer be switched to next position) To clean the connection piece and the rotor proceed as follows (see Fig.
4.2 Maintenance and servicing 35 36 37 38 Fig. 9: Assembling the suppressor 35 Screw nut 37 Suppressor rotor (6.2832.000) 36 Connection piece (6.2832.010) with input and output leads 38 Suppressor holder 6 Clean connection piece • Clean the sealing surface of connection piece 36 with the aid of a lint-free cloth and ethanol.
4 Malfunctions – Maintenance 4.2.7 Exchanging the suppressor Exchanging the suppressor in the suppressor block of the 753 Suppressor Module may be necessary in the following cases (see also section 4.1): • Loss of suppressor capacity which cannot be remedied (reduced phosphate sensitivity and/or strong rise in baseline) • Blockage of the suppressor which cannot be remedied (the suppressor can no longer deliver solutions) Both the 6.2832.000 suppressor rotor as well as the 6.2832.
4.2 Maintenance and servicing 6 Insert connection piece • Insert new connection piece 36 in suppressor holder 38 in such a way that connection "1" is at the top and that the three lugs on the connection piece fit in the corresponding openings of the holder. • Screw nut 35 onto the thread of suppressor holder 38 manually (do not use tools). 7 Connect and condition the suppressor • Reconnect the suppressor to the IC system (see section 2.3.2 and section 2.4.2).
4 Malfunctions – Maintenance • By rotating the suppressor block or with the aid of a mirror check the position of the suppressor rotor according to Fig. 10: at least one of the three holes of the suppressor rotor must be partly or completely visible through the opening at the bottom of the suppressor block. • Repeat the procedure 2-3 times; wait at least 10 s each time before the key is operated.
