The role of spectrophotometer in forensic pharmacology and toxicology
The fact is that spectrophotometers and color analysis play a crucial role in the analysis of forensic pharmacology and toxicology. Although microscopy is an important tool in forensic analysis, spectrophotometers have the power to analyze visible light and require only a small sample size for analysis. In addition, various spectroscopic methods, such as ultraviolet (UV), infrared (IR) and near infrared (NIR), can evaluate different areas of the visible spectrum without affecting the integrity of the sample, thus allowing multiple analyzes of a single piece of evidence .
Pharmacology and Toxicology Sample analysis is important for medical and legal researchers as it provides the ability to make information about cause of death, intoxication and / or possible drug use. Evidence collected at the crime scene may include unknown medications or only traces of substances that need to be analyzed. If a substance has been taken, it may be less concentrated and, in some cases, the chemical may change significantly. Advanced Spectrophotometers use color to analyze the chemical structure of a sample by measuring its absorbance. With the beer rule, forensic analysis separates the properties of unknown substances by color absorption and output data. This process is usually used as a preliminary test to determine the purpose of further testing of unknown compounds.
