3 Capillaries and Fittings

Hints for Successful use of Capillaries and Fittings

• Never overtighten a fitting.

• Never cut a capillary

• Take care when you bend a capillary (diameter never below 40 mm).

• Avoid the use of alkaline solutions (pH > 8.5) which can attack the fused

silica from the capillaries.

• When connecting, press the capillary smoothly into the fitting to avoid air

gaps.

• If a capillary leaks, never retighten it under flow.

• A blocked capillary can often be cleaned by flushing it back. Acetone is

recommended for this.

• Take care when applying module doors, not to crush capillaries.

• A broken capillary can release silica particles in the system.
