Chemical Sciences


Facilities for carrying out the chemical analysis of viscera, NDPS(Narcotic drugs and Psychotropic substances), remnants of accelerants in arson cases, etc. with help of sophisticate instruments like LCMS, HPLC, HPTLC, GC, UV & IR Spectro-photometers exist in this division. Examination of trap cases & other miscellaneous cases are also carried out in this division.The details of expertise of the Chemical Sciences Department is given below:
