STRENGTH AND STABILITY TESTING FOR COMPOUNDED …
www.usp.orgJan 13, 2014 · The PDA (photodiode array) detector is a device that scans from about 200 nm up to 400 nm in the UV range (and can reach 700 nm in the visible range in some instruments). The full array scans the eluent coming from the HPLC every second or so. The software starts at the beginning of a peak and makes scans (basically by “slicing” it into ...

The object stays fixed to the detector and the illumination spot is moved in respect to them. (D) Laser Scanning Microscopy (LSM). Point source illumination and integrating point source detector like a photomultiplier tube (PMT) or avalanche photodiode (APD).
