With a 2998 PDA detector, when acquiring data only for a specific wavelength, is the light that hits the sample only for that wavelength? - WKB223416
Article number: 223416
ENVIRONMENT
- 2998 Photodiode Array Detector
- ACQUITY UPLC PDA Detector
- ACQUITY UPLC PDA eλ Detector
- 2996 PDA Detector
ANSWER
- Even when the PDA detector does not acquire 3D data by selecting a single wavelength from the 2D channel tab, the cell is exposed to light of all wavelengths.
- With UV detectors such as the 2489 UV/Vis Detector and the ACQUITY UPLC Tunable UV Detector, only light of the selected wavelength reaches the cell.
