Varian 900-LC Series Liquid Chromatograph
•
Store cylinders in a well ventilated area away from heat, direct
sunshine, freezing temperatures, and ignition sources.
•
Mark cylinders clearly so there is no doubt as to their
contents.
•
Use only approved regulators and connections.
•
Use only connector tubing that is chromatographically clean
(Varian part number 0391832600) and has a pressure rating
significantly greater than the highest outlet pressure from the
regulator.
Storage Cylinder Instructions
Cylinders containing gas under pressure should be firmly secured
to a rigid structure, and the storage area must be adequately
ventilated.
Never locate gas cylinders near a source of ignition, or in a
position that is subject to direct heat. Gas storage cylinders often
incorporate a pressure release device which will discharge the gas
at a predetermined temperature, usually around 52 °C (125 °F).
If gases are to be plumbed from a remote storage area to the
instrument site, ensure that the local outlets are fitted with stop
valves, pressure gauges and suitable regulators which are easily
accessible to the instrument operator. The gas outlets must be
provided within 1.5 metres (5 feet) of the instrument
High Pressure Hazards
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 personal protective equipment 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.
•
Read and adhere to all NOTES, CAUTIONS, and WARNINGS
in the manual.
•
Always keep the doors and covers closed during operation.
