Detailed explanation-1: -Gas chromatography, or gas-liquid chromatography, involves using a liquid stationary phase and a gas mobile phase. In forensics, gas chromatography is used to determine if a deceased person has taken any alcohol or drugs prior to death, as well as determining if they had been poisoned.
Detailed explanation-2: -In forensic investigations, gas chromatography is used in toxicology screening to determine if a deceased person has ingested drugs or alcohol prior to death. It can also be used to tell if a victim of crime has been poisoned.
Detailed explanation-3: -Separation of complex mixtures (known as chromatography) is an essential tool in forensic science. It is routinely used to identify and compare samples of drugs, explosives, inks and biological samples such as saliva, urine, blood and other.
Detailed explanation-4: -Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis.
Detailed explanation-5: -Another common use for paper chromatography is ink analysis. For example, forensic scientists can analyze a check at a bank for forgery. This method of chromatography allows lab technicians to separate the pen ink from the document to determine if the ink matches what the suspect had with them.
