Wavelength Scanning Test Menu
The Wavelength Scanning test technique lets you measure the absorption or percent
transmission spectrum of a sample. You can use scans to determine peak wavelengths or to
evaluate the quality of a material.
This test technique is useful when using colorimetric reagents for which the test kit
manufacturer does not specify a wavelength parameter for the test kit. Always follow the
reagent instructions provided by the test kit manufacturer when creating a custom method.
Note: If the manufacturer does not specify the factor or equation for obtaining the concentration
of the test kit, the
Standard Curve test technique should be used with prepared standards to
determine the factor or equation for the reagent.
Use Scanning Test Technique:
• To scan samples by setting parameters, collecting a baseline scan and scanning a sample
•
To view and manipulate scanning data, including rescaling graphical scan data,
determining peak height using a 3-point net equation, calculating the area under a curve
and labeling peaks and valleys
• To recall existing scanning methods
