DESCRIPTION& OBJECTIVES
Aim and objectives:
The course is aimed at describing the students the value of forensic analysis in chemistry and the knowledge of advanced techniques and methods often used in forensic analysis. At recent times, and especially in Pakistan, the significance of the forensic study has become of great importance. This subject will integrate the concept and techniques developed in chemistry, physiology and biochemistry, and apply them to the pharmacology and detection of drugs and toxins.
Following objectives will be accomplished in the course contents;
Description: The course contents are designed according to the guidelines by HEC. Forensic science is interdisciplinary in nature. Forensic science is the application of scientific principles to matters involving the law. Forensic chemistry is a specialized area of forensic science involving the application of chemical principles and techniques to the field of forensic investigation. The role of forensic chemistry in criminal investigations is vast and ranges from techniques used to collect and preserve evidence, to complex chemical procedures used to identify elements and compounds. Identification procedures are highly reliable and are frequently based on the chemical and physical properties of the substance supported by data obtained from analytical analysis. Most chemical techniques used for isolation, purification, and identification are valid forensic techniques; however, chemical analysis differs from forensic chemical analysis, as mostly the forensic analysis are proceeded in regulatory and judiciary perspectives
Learning Outcome: The contents are aimed to develop understanding of the students about the basic principles of forensic science and the importance of forensic analysis in solving the crime issues and role in judiciary.
