Warnings and Safety Precautions

7) Repair or replace faulty power cords and all communication cables.
8) Many organic solvents and buffers are toxic. Make certain that you know the
toxicological properties of all mobile phases that you are using.
9) The toxicological properties of many samples may not be well known. If you
have any doubt about a sample, treat it as if it contained a potentially
harmful substance.
10) Wear protective eye goggles when handling mobile phases or operating the
instrument. An eye wash facility and a sink should be close to the unit. If any
mobile phase splash on the eyes or skin, wash the affected area and seek
medical attention.
11) Dispose of all waste mobile phase in an environmentally safe manner that is
consistent with all local regulations. Do not allow flammable and/or toxic
solvents to accumulate. Follow a regulated, approved waste disposal
program. Never dispose flammable and/or toxic solvents through the
municipal sewage system
12) PEEK tubing is used in a variety of locations. While this polymer has superb
chemical resistance to most organic solvents, it tends to swell when it is
contact with CHCl
concentrated acids such as Sulfuric Acid and Nitric Acid (swelling or attack
by acid is not a problem with short flushing procedures).
Do not use PEEK tubing that is stressed, bent or has a kink.
13) Wear protective eye goggles when handling fused silica tubing (i.e.
installation, cutting etc.)
14) If a buffer is used as a part of the mobile phase, flush the system with
several volumes of a methanol/water (50/50) before it is shut down. This will
prevent salt buildup inside the unit.
15) Do not use the instrument in ways other than those indicated in the
instructions given in this manual.
