The work in the chemistry division involves the chemical analysis & characterization of chemical substances present in various types of exhibits, both qualitative as well as quantitative.

• Determination the profile of adulterants in petroleum products like kerosene, diesel, petrol, mobil, lubricating oils and their residues as such in burnt articles
• Analysis of dyes in trap cases
• Determination of acids, alkalis and their residues in different articles including clothing materials
• Analysis of vegetable oils
• Analysis of precious metals like Gold, silver, platinum etc.
• Analysis of ores
• Comparative examination and analysis of cement, mortar and concrete materials
• Analysis of soaps, detergents and related products
• Analysis and comparative examination of different spurious, substandard / duplicate goods like tooth paste, tooth powder, pain balm, cosmetics, paints, spices etc
• Undertake meticulous examination of different crime scenes including fire / arson scene to know origin and cause of fire

• Solid materials (e.g. cloth materials, debris etc.) suspected to contain any inflammable substance will be preserved in air tight non-reactive plastic packet immediately after collection.
• In cases of arson the unburnt portion of the material stored in godowns / warehouses etc. should be sent as control.
• In cases where it is not possible to collect whole affected remnants from an immovable object, part of remnants from a suitable position or a cotton swab from the affected objects should be collected and preserved accordingly.
• In cases of suspected adulteration of petroleum products like petrol, H.S. Diesel oil, kerosene etc. the substance will be kept in a dry and clean plastic / glass bottle fitted with lid. At least one litre of liquid petroleum product is required for examination and characterization.
• Liquid substances suspected to be acidic or alkaline to be preserved in glass container with hard plastic lid.
• Any cloth materials suspected to contain acidic or alkaline substance to be preserved in dry and clean thick plastic / glass container.
• Sample like cement to be preserved either in dry and clean plastic packet or in plastic container. At least 1 kg of sample is required for examination. For comparison between different cements "Control Sample" should be supplied.
• For analysis of concrete materials at least 2 kg of sample along with control sample where applicable should be supplied.
• For examination and comparison of suspected spurious liquid (e.g. cosmetic goods, edible oil etc.) and solid (e.g. zarda, detergent etc.) a suitable control sample of respective brand to be supplied.
• Samples for examination should be sent immediately after collection.
