The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples. By ...
IN the past few years, several workers have shown 1–5 that infra-red spectra can be presented continuously on a cathode ray tube. The presentation of spectra in this way, in scan times as short as ...
The V-660 is a double-beam spectrophotometer utilizing a double monochromator and a photomultiplier tube detector. The use of a double monochromator provides high resolution with extremely low stray ...
