General Routine Maintenance in an LC System

Perform the maintenance procedures listed in the table at regular intervals to ensure optimum

performance and maximum uptime of the detector. The exact maintenance schedule for the

detector will depend on a number of factors, such as sample type, mobile phase composition,

sample cleanliness, etc.

Frequency What you should do...

Daily

Inspect the flow connections for indications of leakage or

restrictions.

When using buffer solutions, flush the system thoroughly after use.

Use a solvent that does not contain buffers or salts.

Check that the solvent bottle(s) contain sufficient mobile phase for

the expected analysis.

Regularly

Check the drain tubes connected to the drain ports on the bottom

right of the detector (→ page 34). Verify that the tubings are

unclogged and are routed below the drain port. Check the volume of

the liquid in the waste container and empty as needed.

Inspect the tubing for possible damage, such as cracks, nicks, cuts,

or blockage.

Check all electrical connections to ensure that they are properly

seated.

Annually

Have a service representative check the detector and perform

preventive maintenance once a year to prevent contamination and

excessive wear.

The detector is just one component of a chromatographic system. The performance of the

detector will reflect the performance of the overall HPLC system. To maintain optimal

analytical performance, perform routine maintenance on each of the various HPLC system

components (e.g., pump, autosampler, etc.).
