2.3 Operating Principle and Functional Description
2.3.2 Gas Leak Sensor
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
exceeds the explosion limit, it may cause spontaneous
combustion with dangerously explosive results.
When using a flammable and volatile chemical, be sure to
check for leakage from the instrument flow path and
ventilate the laboratory room adequately.
Touching Hot Part Could Result in Burns
The column oven becomes very hot during operation and
can severely burn you in case of contact with it.
Before column replacement, open the column oven door
and wait until the inside temperature of the column oven
decreases down to room temperature.
