■■■■■■■■■■■■■■■■■■■■■■ 1.2 About the documentation 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. About the documentation Caution Please read through this documentation carefully before putting the instrument into operation.
The electrical safety when working with the instrument is ensured as part of the international standard IEC 61010. Warning Only personnel qualified by Metrohm are authorized to carry out service work on electronic components. ■■■■■■■■ 872 Extension Module IC Pump...
■■■■■■■■■■■■■■■■■■■■■■ 1.3 Safety instructions Warning Never open the housing of the instrument. The instrument could be damaged by this. There is also a risk of serious injury if live components are touched. There are no parts inside the housing which can be serviced or replaced by the user.
■■■■■■■■■■■■■■■■■■■■■■ 1 Introduction 1.3.4 Flammable solvents and chemicals Warning All relevant safety measures are to be observed when working with flammable solvents and chemicals. Set up the instrument in a well-ventilated location (e.g. laboratory ■ flue). Keep all sources of flame far from the workplace. ■...

■■■■■■■■■■■■■■■■■■■■■■ 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 con- tains 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 start- up .
■■■■■■■■■■■■■■■■■■■■■■ 4 Installation Deaerating the high pressure pump The instrument must be connected to the PC and switched on to deaerate the high pressure pump. Figure 22 Deaerating the high pressure pump Syringe 10 mL 6.2816.020 Luer connector For aspirating the eluent. On purging needle.

■■■■■■■■■■■■■■■■■■■■■■ 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 .

■■■■■■■■■■■■■■■■■■■■■■ 6 Operation and maintenance 6.1.4 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 elu- ent salts from forming crystals which may cause subsequent damage. rinse all capillaries and the Dosino with methanol/ultra pure water ■...
■■■■■■■■■■■■■■■■■■■■■■ 6.4 High pressure pump 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. metha- nol, acetone, acetonitrile) to aqueous eluents generally accelerates lipophilic ions. 6.3.2 Operation 6.3.2.1...
■■■■■■■■■■■■■■■■■■■■■■ 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).
■■■■■■■■■■■■■■■■■■■■■■ 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.
■■■■■■■■■■■■■■■■■■■■■■ 6 Operation and maintenance Remove the spring retainer, spring and the inner plastic sleeve ■ from the piston cartridge and lay by.

■■■■■■■■■■■■■■■■■■■■■■ 6.4 High pressure pump Replacing the piston seal The 6.2617.010 special tool (see Figure 27, page 44) is necessary in order to remove the piston seal from the pump head. It consists of two parts: a tip for removing the old piston seal and a sleeve for inserting the new piston seal.
