7. Conclusion
Still widely used in laboratories and industry, molecular absorption spectrophotometry has benefited from technological improvements and powerful computing resources, enabling it to extend the scope of its applications, especially if we include the near infrared range, which is often offered as an option in commercial spectrophotometers. The near infrared range is the field of choice for the food and petrochemical industries...
It's a well-documented technique, with numerous publications from manufacturers, universities and organizations available on the Internet. Performance verification is easy, with certified methods and reference materials. Implementation is fairly straightforward – except for sample preparation in certain cases! – and does not require any special utilities. The purchase price of spectrophotometers is reasonable, as are their operating costs....

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:
