Agilent Sample Introduction Pump System SIPS 10/20 User’s Guide
NOTE
Make sure that you do not let too much air into the diluent tubing when you
remove it from the Mariotte vessel. Allow sufficient time for the air to clear
before remeasuring.

Observe the movement of the bubble in the diluent line. If it is
not travelling towards the nebulizer, slowly wind out the
nebulizer thimble until the bubble travels towards the nebulizer.
It should take approximately 25–30 seconds for the bubble to
travel 100 mm in the diluent tubing with the pump running at
100%.
TIP
If the nebulizer blocks, replace the diluent in the Mariotte vessel because
blocking causes the flow of sample to be reversed, towards the Mariotte vessel,
leading to contamination of the diluent and incorrect results.
Automatic Calibration from a Single Standard
Automatic calibration from a single standard can be performed using
either the single pump system of the SIPS 10 or the dual pump
system of the SIPS 20.
SIPS 10
To calibrate a method using the SIPS 10:
1
Develop or modify a method (flame analysis) as per your
analytical requirements (refer to the online help for details).
2
To incorporate SIPS operation into the method, enable the Use
SIPS check box on the
Type/Mode
page (the first page in the
Edit Methods
dialog).
