A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to ...

Melamine is an organic-based chemical usually found as enriched white nitrogen crystals. Since melamine is used for manufacturing food dishes and containers, there are concerns about melamine ...

An observational technique with the Carnegie image tube is described which results in relative spectrophotometry for very faint stars. It is found that a 40-inch (1.02-m) telescope with an image-tube ...

Many lab processes involve regularly monitoring water quality or inspecting liquid compounds. Spectrophotometry is an integral part of this analysis, so choosing spectrophotometer equipment carefully ...
