LC Safety Practices
High Pressure Hazard
If a line ruptures, a relief device opens, or a valve opens accidentally under pressure,
potentially hazardous high liquid pressures can be generated by the pump causing a high
velocity stream of volatile and/or toxic liquids.
Wear face protection when you inject samples or perform routine
maintenance.
Never open a solvent line or valve under pressure. Stop the pump first
and let the pressure drop to zero.
Use shatter-proof reservoirs capable of operating at 50/60 psi.
Keep the reservoir enclosure closed when the reservoir is under
pressure.
Read and adhere to all NOTES, CAUTIONS, and WARNINGS in the
manual.
Flash Chromatography
The operator should be familiar with the physico-chemical properties of the components
of the mobile phase.
Keep solvents from direct contact with the polyurethane supply tubing as certain solvents
will cause weakening and leaks with possible bursting.
All components of the system should be connected to a common power supply and
common ground. This ground must be a true ground rather than a floating ground.
Non-polar solvents can develop a static charge when pumped through the system. All
vessels that contain mobile phase (including tubing and collection vessels) must be
grounded to dissipate static electricity.
Employ static measuring and static discharge devices (e.g., air ionizers) to safeguard
against the buildup of static electricity.
