Ensure the exhaust system is working. To do this, hold a thin
single-ply tissue up to the mouth of the extraction hood. The
tissue should be drawn towards the hood.
Check the gas supplies to make sure you have enough gas to
complete your analysis. You must also check that the acetylene
cylinder pressure is above 700 kPa (about 100 psi) to ensure that
acetone is not drawn into the instrument.
Set the delivery pressure of the gases to the following:
Acetylene
Air
Nitrous oxide
Inspect the gas hoses for damage, replacing any damaged hoses.
Turn on the gas supplies to your instrument and test all hoses
and connections for leaks. If a leak is found, repair it
immediately.
Load a worksheet and develop the method(s) as per your
analytical requirements.
Optimize the system.
