Using Forensic Chromatography For DUI

 Chromatography is a method used in laboratories that is used in separation and analysis of concentrations of chemical compounds. Forensic science, on the other hand, deals with identifying, recognizing and interpreting evidence. After that science is used to process the evidence so that it can be understood. Forensic chromatography involves the analysis of trace chemical compounds found in samples of urine, hair, blood, oral fluids or other physical evidence. It aims to define the concentrations of these compounds; that swell as their effects. Forensic Chromatography may involve different types of chromatography. Gas chromatography that is the section of compounds through columns using gas as a mobile phase can be used.. The separation of the compounds through the column results from ins in lation of the desired compound. At this stage, preparative chromatography can be deemed to have taken place, and the subject can be taken for further chromatography tests, or it can be analyzed. Liquid chromatography can also be used.. In this case, a liquid is the mobile phase. The substance being studied is passed through a solid stationery that filters it and brings out the desired components of the substance. Affinity chromatography is another branch of chromatography is used in forensic chromatography. It is highly specific and is used to identify trace amounts of compounds that provide evade difficult to observe. Ion exchange chromatography that is used to separate substances based on their charges can also be used in forensic Chromatography.



Forensic Chromatography is used more often in courts now according to one of the recent graduates of Axion Training Institute, Nathan Dineen who specializes in drunk driving defense and OWI Wisconsin law. An individual who has been charged with DUI can be tested and the actual ethanol concentrations in the blood easily found out. It is also used in solving crimes that look seemingly unsolvable through analysis and separation of trace compounds such as hair strands to produce evidence against arrested persons. The chromatography used narrows down biological and chemical traces found in physical matter. Qualitative analysis of fibers and soil samples left behind in crimes scenes can be very useful in forensics. Forensic chromatography is used to provide accurate, precise and concise details of the subject matter presented for tests. it can be used to match DNA samples, blood and semen samples as well as urine samples making it easier to tie people to crime scenes. It is an important field of science as it used in testing traces of drugs during drug tests as well as in pathology where knowledge in the field is used in finding out if there are chemical substances in an individuals body, that may have lead to their death. An may use this as evidence in the court of law. It aims at demystifying science and exposing minute details for study. Forensic chromatography has also been used to study the blood components of an individual to determine if there is presence of foreign substances. This is useful in natural prescription of medication by doctors.
