3.6 Before Performing Analysis

This chapter describes the basic items to be careful about before
starting analysis.
Ignition of Flammable Chemicals
• This instrument is not explosion-proof. In unattended
operation, do not use organic solvents having an
ignition point below 70 C.
• Beware of ignition hazard when using flammable
chemicals such as organic solvents.
(a) Do not bring a heat or flame source near the
instrument.
(b)
Well-ventilate the laboratory room where the
instrument is used.
(c)
Always check the following conditions. If an
abnormality is found, stop operation immediately.
 Leakage of solvent or waste solution.
 Leakage of solvent inside the instrument.
• When using flammable chemicals, be careful about
possible ignition due to static electricity. To prevent
the build-up of static electricity, use a conductive
container for waste solution and provide proper
grounding connection to it.
Explosion of Vapor from Flammable Chemicals
If a flammable chemical such as organic solvent leaks
from the flow path of the instrument and its vapor
concentration reaches the explosion limit, it could cause
spontaneous combustion with dangerously explosive
results.
When using a flammable and readily volatile chemical, be
sure to check for leakage from the instrument flow path
and ventilate the laboratory room adequately.
