6. Fields of application
6.1 A few examples
Spectrophotometry is used in many fields: chemistry, pharmaceuticals, environment, food processing, biology, etc., both in the laboratory and on industrial sites. The possibilities offered by multivariate analysis, which enables the analysis of several constituents while limiting spectral or physico-chemical interference phenomena, have opened up new uses, particularly for industrial analysis. Manufacturers publish numerous application notes (see Internet addresses in ).
In the pharmaceutical industry, many drug dissolution tests are carried out using UV-VIS absorption spectrophotometry. The same applies to the food industry. Procedures are codified and described on the websites of organizations such as Pharmacopeia (USP...

Websites
While the Internet is an extraordinary source of information, finding the right information is not always easy, particularly in the scientific and technical fields. The search for information is generally carried out using search engines, or meta-search engines that combine results obtained from several engines.
Two difficulties appear for this research:
