New era of crime has evolved with newer technologies and deeper sense of hiding the crime by the criminals. To overrule the latest emerging crime scenario, it is needful to have strong sense of collection and separation of necessary clues. The relevant information or piece of information of evidence is only significant out of the huge irrelevant other material collected at the crime scene. Whereby a single hair of accused in a rape and murder case becomes highly important evidence when separated from clothe of child deceased gets matched with the DNA of suspected accused. Separation from manual to technical and followed by identification is the basic theory of solving various crimes. In forensic sciences separation of physical, chemical, biological evidence and its identification is a necessary step. In toxicology the separation of poisons from visceral tissues and blood is a primary requirement. Whereas separation and analysis of alcohol with its concentration is very significant in drunken cases, the analysis of overdose drugs in cases of doctors negligence, drugs cases related to suicide/ murder, murder cases by use of cyanide, use of drugs for making fled of gangsters from police custody are all different traditions of crime but solved with a common technique that is separation. The use of various forms of chromatography for separation and detection by mass spectrometry is must to stand in international standards of identification. Uses of specific standard methodologies are acceptable in court of law and the establishment of connection of evidence with various mysteries provides justice to society. Hence a brief view on different problems and their solution is discussed that gives new insight to investigation.
