In this division examination of “trace evidence” materials like soil, paint, glass, metal, fiber, examination of tool marks and restoration of erased numbers/marks, etc. in murder, theft, vehicle accident and other cases is done. For the examination of these exhibits the instruments like Atomic Absorption Spectrophotometer, Simultaneous Thermal Analyzer (STA), and Energy Dispersive X-Ray Spectrophotometer (EDXRF) are used. Video Spectral Comparator (VSC-5000) is used for examination of ink on forged documents like duplicate currency notes, fake stamps, stamp papers, lottery tickets, certificates and bank cheques.
