Jet Cleaning Procedure
Use Agilent cleaning kit, part number 9301-0985
1. Run a cleaning wire through the top of the jet. Run it back and forth a few times until
it runs smoothly. Be careful not to scratch the jet. (Do not force too large a wire or
probe into the jet opening or the opening will become distorted. A loss of sensitivity,
poor peak shape, and/or lighting difficulties may result if the opening is deformed.)
2. Fill an ultrasonic cleaning bath with aqueous detergent, and place the jet in the bath.
Sonicate for five minutes.
3. Use a jet reamer to clean the inside of the jet.
4. Sonicate again for five minutes.
Note: from this point on, handle the parts only with forceps!
5. Remove the jet from the bath and rinse it thoroughly, first with hot tap water and then
with a small amount of GC-grade methanol.
6. Blow the jet dry with a burst of compressed air or nitrogen, and then place the jet
on a paper towel and allow to air dry.
