2 Installation 2.4.3 Settings in the «IC Net 2.1» program During configuration of the 793 IC Sample Prep Module, the IC Net assistant “New system wizard” requires the definition of an “Event line” for the SP Module A. Although this is not installed you must enter any unused “Event line” to enable the program to proceed. Actually, the SP Module A is controlled by the 766 sample processor (see Fig. 8). The signal for switching the internal IC Suppressor Module is not provided by the 766 program.
3.1 Handling the SP Module A 3 Operation 3.1 Handling the SP Module A General The SP Module A of the 793 Sample Prep Module consists of a total of three cation exchange units which are in turn used for cation exchange, regenerated and rinsed with water. In order to record each new chromatogram under comparable conditions a freshly regenerated cation exchange unit is normally used. Switching is either carried out automatically together with valve switching or manually.
3 Operation 3.2 Manual operation The 793 IC Sample Prep 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 793 IC Sample Prep Module is switched on and off using mains switch 13 on the rear of the instrument (see Fig.
3.3 Operation via 732 IC Detector 3.3 Operation via 732 IC Detector When operating the 793 IC Sample Prep Module together with the 732 IC Detector and the 733 IC Separation Center both pump and the SP Module A on the 793 IC Sample Prep Module can be operated and switched automatically without the program “IC Net”.
3 Operation Switch on: Switch off: >PROGRAM/edit remote XXX.X min 1✴✴✴✴✴✴✴ >PROGRAM/edit remote XXX.X min 0✴✴✴✴✴✴✴ Switch pump on/off 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).
3.3 Operation via 732 IC Detector Rotate SP Module A 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 ). At each event the SP Module A can be brought into the next position by setting remote output lead 2 to 1 (on, active, 0 V). This lead must later be returned to the setting 0 (off, inactive, open) before the SP Module A can be switched to the next position.
4 Malfunctions - Maintenance 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 o pump o eluent o 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).
4.1 Malfunctions and their rectification Actuator moves to next position but display lamp 7 no longer lights up Actuator is not switched to next position (display lamp 7 no longer lights up) x SP Module A dry x Rinse all 3 actuator units with solution for at least 10 min. x SP Module A temporarily in the wrong position x Switch instrument off and then on again. Switch off SP Module A remote operation with key 6 and operate key 8 . Check whether display lamp 7 lights up.
4 Malfunctions - Maintenance 4.2 Maintenance and servicing 4.2.1 Care The 793 IC Sample Prep 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.
4.2 Maintenance and servicing 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 4 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 Malfunctions - Maintenance 4.2.5 Regeneration of the cation exchange material If the actuator 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 HClO4). This diminishes the capacity of the actuator units.
4.2 Maintenance and servicing 4.2.6 Cleaning the SP Module A Cleaning the SP Module A may be necessary in the following cases (see also section 4.1): x Blockage of the SP Module A which cannot be remedied (the SP Module A can no longer deliver solutions) x Obstruction of the actuator which cannot be remedied (the actuator can no longer be switched to next position) To clean the connection piece and the rotor proceed as follows (see Fig.
