A Brief Background to Spectrophotometry

(VIS) spectrophotometry has become the method of choice in most laboratories concerned with the identification and quantification of organic and inorganic compounds across a wide range of products and processes. Applied across research, quality, and manufacturing, with continuing focus on life science and pharmaceutical environments,

DETERMINATION OF VITAMIN C CONTENT IN COMMERCIAL …

Apr 14, 2021 · Spectrophotometry is one of the most frequently used simple methods, because vitamin C is able to absorb UV ray [35]. Direct ultraviolet (UV) spectrophotometry can provide a fast, simple and reliable method for the determination of L-ascorbic acid. Absorption of UV light by the sample matrix is a major problem due to

UV/Vis/NIR RANGE Long the industry standard in spec-trophotometry, the LAMBDA 950 uses a gridless PMT with Peltier-controlled PbS detector to achieve high- performance testing across the spectral range up to 3300 nm. The UV/Vis resolution reaches 0.05 nm, while the NIR resolution reaches up to 0.20 nm.
