Flammable solvents hazard
Never let the nitrogen supply pressure fall below 400 kPa (4 bar, 58 psi)
during analyses that require flammable solvents. Connect to the LC output
with a gas-fail connector to stop the LC solvent if the nitrogen supply fails.
Warning: To prevent the ignition of accumulated solvent vapors inside
the source, maintain a continuous flow of nitrogen through the source
whenever significant amounts of flammable solvents are used during
instrument operation.
