Irradiated tyrosine underwent a significant increase of the absorbance and finally yielded an exponential absorption spectrum, with close resemblance to the behaviour of a protein-rich and humic-poor sample of subterranean water. In contrast, irradiated humic acids underwent photobleaching in a similar ...
The application of spectral analysis to water quality monitoring is an important developing trend in the field of modern environment monitoring technology.The principle and characteristic of water quality monitoring technology based on UV-Vis spectrum analysis are briefly reviewed.And the research status ...
Nänikon, July 2022 – With its new EasyPlus UV/VIS instrument line METTLER TOLEDO sets a new standard of versatility and ease of use in water analysis. Spectrum scans, watercolor, and substances in water can be measured using only one compact instrument. How to make water analysis easi...
Figure 1. Water vapor spectrum collected on the Cary 6000i InGaAs and the Cary 5000 PbS spectrophotometers A Signal Averaging Time (SAT) of 10 seconds was used on the Cary 5000 compared to 0.1 seconds on the Cary 6000i. Also, a SBW of 0.05 nm was used on the Cary 5000 compared to ...
(SNV) and 1 st Derivatives were compared to determine the optimal pretreatment method for analysis .Spectral variable selection is an important strategy in spectrum modeling analysis ,because it tends to parsimonious data representation and can lead to multivariate models with better performance .In ...
