x Protection against static charges

Electronic components are sensitive to static charging and can be

destroyed by discharges. Before you touch any of the components

General precautionary rules

x Handling of solvents

Check all pump tubings and all input and output lines periodically for

possible leaks. Follow the relevant instructions regarding the handling

of flammable and/or toxic solvents and their disposal.

x Regular exchange of pump tubings

Pump tubings are consumable material and must be replaced from

time to time (see Section 4.2.4). Suitable measures must be taken so

that any leak which might occur in the pump tubing or connections

during unattended operation will cause no damage (placing the

instrument at the bottom, collection device for any liquid which may

leak out).
