2Maintenance
To clean the capillary
To maintain proper cleanliness, handle the ion transport capillaries with
protective gloves.
4 Rinse the ion transport capillary and graduated cylinder several times with
deionized water.
5 Fill the graduated cylinder with deionized water and sonicate the
graduated cylinder with the ion transport capillary for 10 to 15 minutes.
6 Remove the ion transport capillary from the graduated cylinder and remove
the pipette tip (if one was used).
7 Blow out excess water from the ion transport capillary bore using
AeroDuster or oil-free pressurized gas.
8 Install the ion transport capillary in the LC/MS Desolvation Assembly:
a Lubricate the ion transport capillary surface with isopropanol and insert
carefully into Desolvation Assembly. Support the front and rear of the
capillary and keep it level during installation.
When 2 to 3 cm of the capillary remains extended from the Desolvation
Assembly, the capillary “holds up” on the rear contact spring. Continue
to apply pressure until approximately 1 cm remains extended from the
Desolvation Assembly.
b Lubricate the ion transport capillary tip with isopropanol and install the
Capillary Cap.
c Install the threaded Spray Shield by turning clockwise.
