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.
