Description
ASTM E1657 – Standard Practice for Testing Variable-Wavelength Photometric Detectors Used in Liquid Chromatography
1.1 This practice covers the testing of the performance of a variable-wavelength photometric detector (VWPD) used as the detection component of a liquid-chromatographic (LC) system operating at one or more wavelengths in the range 190 to 800 nm. Many of the measurements are made at 254 nm for consistency with Practice E685. Measurements at other wavelengths are optional.
