ABSORBANCE AND TRANSMITTANCE TESTS
Absorbance and transmittance tests are available in the ALL TESTS menu. These tests can be used in con-
junction with user-developed methods to analyze samples and obtain results in terms of absorbance (ABS) or
percent transmittance (% T), or to prepare user calibration curves. Wavelength choices are 420, 470, 520, 570,
620, and 660 nm. Sample cell viewdepth choices are 15 and 25 mm. A nonpreprogrammed timer is available
as a footer option. In general, the following steps are required to perform absorbance and transmittance tests:
• Select Absorbance or Transmittance from the ALL TESTS menu.
• Select a wavelength.
• Confirm test name and wavelength.
• Prepare a blank and ZERO the Colorimeter.
• Prepare sample and READ the sample.
The following example shows how to perform an absorbance test with results expressed in terms of ABS. The
same procedure is used to perform a transmittance test with results expressed in terms of % T.
