Cell Test Evaluation
The Agilent ChemStation calculates the intensity ratio automatically. The
intensity ratio (typically between 0.5 and 0.7 for new standard flow cells and
0.1 to 0.3 for new mico- and high pressure cells) is dependent on the degree of
contamination of the flow cell windows, and on the type of flow cell used.

Test Failed (low ratio value)
NOTE
This test can be used for the standard flow cells only. The nano flow cells will give very low
values due to their design.
Probable cause Suggested actions
1 Absorbing solvent or air bubble in flow cell.
Ensure the flow cell is filled with water, and free
from air bubbles.
2 Dirty or contaminated flow cell.
Exchange the flow cell windows.
