￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4.6 High pressure pump 4.6.2 Deaerating the high pressure pump The high pressure pump will only operate perfectly if the pump head contains no more air bubbles. Therefore it must be deaerated during initial start-up and after every change of eluent. Caution The high pressure pump must not be deaerated before the initial startup .
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4 Installation Deaerating the high pressure pump The instrument must be connected to the PC and switched on to deaerate the high pressure pump. 5 4 5 6 3 7 2 5 1 Figure 22 Deaerating the high pressure pump 1 Syringe 10 mL 6.2816.020 For aspirating the eluent. 2 Luer connector On purging needle. 3 Purging needle 6.2816.040 4 Deaerating capillary 5 PEEK pressure screws, short 6.2744.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4.7 Inline filter 4 Setting the flow rate ￭ ￭ ￭ Start MagIC Net (if not yet started). Ensure that the eluent aspiration tubing is immersed sufficiently in the eluent. Let the high pressure pump run. 5 Aspirating eluent ￭ Aspirate with the syringe (22-1) until bubble-free eluent flows into the syringe. 6 Completing deaerating ￭ ￭ ￭ ￭ 4.7 Turn off high pressure pump. Close rotary knob (22-7). Remove syringe (22-1) from the Luer connector (22-2).
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4 Installation Installing the inline filter Caution Observe the flow direction marked on the filter housing for the connection of the inline filter. 1 Figure 23 2 3 2 4 Connecting inline filter 1 Connection capillary Connects the purge valve with the inline filter 2 PEEK pressure screws, short 6.2744.070 3 Inline filter 6.2821.120 Protects against particles. 4 Connection capillary Connects the inline filter with the pulsation damper.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4.8 Pulsation damper The pulsation damper protects the separation column from damage caused by pressure fluctuations when switching the injection valve, and reduces interfering pulsations during highly sensitive measurements. In order to ensure these functionalities, it must be connected between the high pressure pump (see Chapter 4.6, page 29) and injection valve . The pulsation damper can be operated in both directions.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5 Start-up 5 Start-up The extension module is put into operation together with the IC instrument. Putting IC instrument into operation with extension modules 1 Start MagIC Net. 2 Connect IC instrument to PC and switch on. The extension module is recognized automatically by MagIC Net. 3 Deaerate the high pressure pump (see Chapter 4.6.2, page 32). Additional information can be found in the Start-up chapter in the manual for the IC instrument as well as in the MagIC Net online Help.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1 General information 6 Operation and maintenance 6.1 General information 6.1.1 Care Warning The instrument housing must not be opened by untrained personnel. The instrument requires appropriate care. Excess contamination of the instrument may result in functional disruptions and a reduction in the service life of the sturdy mechanics and electronics.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1.4 6 Operation and maintenance Shutting down If the instrument is shut down for a longer period of time, the entire IC system must be rinsed as follows to rid it of salts in order to prevent eluent salts from forming crystals which may cause subsequent damage. rinse all capillaries and the Dosino with methanol/ultra pure water (1:4), rinse all pump tubings of the peristaltic pump with ultra pure water. ￭ ￭ 6.2 Door Caution The door is made of PMMA (polymethylmetacrylate).
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.4 High pressure pump 6.3.2 6.3.2.1 pH pH changes result in shifts in the dissociation equilibria and hence changes in the retention times. Organic solvents The addition of an organic solvent (e.g. methanol, acetone, acetonitrile) to aqueous eluents generally accelerates lipophilic ions. Operation Supply bottle The supply bottle with the eluent must be connected as indicated in Chapter 4.4.1, Page 24. This is above all important for eluents with volatile solvents (e.g.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6 Operation and maintenance Salt crystals between the piston and seal cause abrasion particles which can find their way into the eluent. These lead to contaminated valves, a rise in pressure and in extreme cases scratched pistons. It is therefore essential to ensure that no precipitates can occur (see Chapter 6.3.2.3, page 40). Caution In order to spare the pump seals, the pump should not be operated dry.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.4 High pressure pump piston is on the left (viewed from the front), and the auxiliary piston is on the right. Cleaning/replacing the zirconium oxide piston Clean one piston after the other as follows: 1 Removing the piston cartridge from the pump head Loosen the piston cartridge with a wrench and unscrew from the pump head by hand.

Press the seal by hand well on the valve housing. 6 Checking the flow direction Rinse the valve in the direction of the arrow on the valve housing and check wether liquid is escaping on the other end.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6 Operation and maintenance Mounting the pump head Note To prevent the pump head from being positioned the wrong way, it is provided with different bore hole depths for the fastening bolts, i. e. a fastening bolt is longer than all others. The bore hole with the greatest depth must therefore be assigned to the longest bolt. If this is not the case, the pump will not function perfectly. 1 Mount the pump head on the pump again using the four fastening screws (20-5).
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.5 Inline filter Changing the filter The flow must be stopped before changing the filter. 1 Removing the inline filter ￭ Unscrew the pressure screws (34-1) from the inline filter. 2 Unscrewing the filter screw ￭ Screw the filter screw (34-4) out of the filter housing (34-2) with the aid of two 6.2621.000 adjustable wrenches. 3 Inserting the filter ￭ ￭ Remove the old filter (34-3) with tweezers.
