UV vs Diode-Array (PDA) Detectors for (U)HPLC - Shimadzu
网页The photo diode array (PDA), also known as the diode array detector (DAD) can measure the entire wavelength range in real time, which may provide other advantages. Figure 1 provides an example from the analysis of cannabinoids by spectral absorbance profile which can be utilized as a second form of analyte confirmation.
How HPLC Detectors Work | Thermo Fisher Scientific - US
网页For UV-Vis detection, chromatographers can choose between three types of detectors: a variable wavelength detector (VWD), diode array detector (DAD), or multiple wavelength detector (MWD). In variable wavelength detection, a single chosen wavelength from the UV-Vis spectrum illuminates the sample.
