ISORI ion spectroscopy instrument - Wing4 (MS-UV/VIS/IR)¶

How to operate the machine¶

• pressure in the He trap must be kept below 4e^-7 mbar (channel #4 TRAP on the pressure meter)

• Q-Delay of the IR laser for OPO-B should be slowly decreased from 400 μs to 290 μs before operation.

Follow Aleks advice. In future, guideline will be made

• Turn off the laser shutter.

• Disable all pulses.

• Switch ISORI to Q1 MS mode and set m/z to 10.

• Switch from “Active low” mode to “None”.

• Set accumulation to 2000 and turn accumulation on.

• Execute “delayed_heat.bat” file at the desktop.

• Turn off laser shutter and pulsing.

• Set laser Q-delay to 400.

• Turn the laser key to off.

• Switch off TSQ multiplier.

• Clean the ESI source and cap it.

• Switch off the ESI source N2 inlet (big plastic knob in the inlet line above your head).

• Check the pressures to verify that He pulses are off and that the source is capped.

• Clean the tables around ISORI.
