Characteristics Of Organic Solvents - Hitachi PRIMAIDE 1440 Instruction Manual

3.6.2 Characteristics of organic solvents

Characteristics of organic solvents as mobile phase for liquid
chromatograph are shown in Table 3-2. Use it for reference.
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.
