Standalone Agilent 50/55 AA Instruments
NOTE
Calibration of the SIPS pressure arm is only provided in version 1.12 (and later
versions) of the on-board software for the Agilent 50/55 AA. The version
number is displayed with the Agilent logo as part of the initialization sequence.
If you do not have version 1.12 (or later), contact your local service
organization to obtain this upgrade.
To calibrate the force of the SIPS pressure arm(s):
1
Turn on the Agilent 50/55 AA instrument but not the SIPS unit.
Wait for the initialization sequence to complete.
2
Load a method that has the SIPS unit enabled. Fit an appropriate
hollow cathode lamp.
3
Place the inlet capillary tube in a beaker of de-ionized water.
Place the outlet tube of the capillary in an empty beaker.
4
Light the flame.
5
Access the Service diagnostic page 54 by holding the ‘Alt' key
down while you type 54 on the numeric keypad. This page is
titled _ SIPS (Installation).
6
The SIPS arm pressure field on this page has a default value of
120. Type in the number ‘70’ using the numeric keypad and press
ENTER to save the value.
7
Turn on the SIPS control module.
8
Press the Results key to go to the Results page.
9
Press the Read key and observe if the liquid pulses in the
capillary tubing.
10
If the liquid is not moving, switch off the SIPS control unit.
11
Repeat Steps 5–10, increasing the SIPS arm pressure setting by 5
units each time until liquid starts to flow.
12
Once you have established the setting which allows liquid to flow,
add 5 to the value. Access the SIPS Installation page (Alt+54) and
type in that number. Press Enter to save this value. This value
will now be used every time the instrument is operated.
