Chemical Analysis for Criminal & Civil Investigations

We identify, confirm, and quantify chemicals in evidential materials—ranging from petroleum products and industrial chemicals to narcotics and post‑explosion residues—using validated forensic protocols and ultra‑modern instrumentation.

Scope of Examination

Petroleum products, cement, explosives & post‑explosion residues, oils & fats, dyes, dangerous drugs (heroin, brown sugar/guard, cocaine, methaqualone, LSD), narcotics (opium, cannabis: charas, ganja, bhang), industrial chemicals, and residues in cases of murder, arson, explosion, theft, cheating, etc.

Court admissible Chain-of-custody rigor Modern instruments

Toxicological Consumption Analysis

In suspected consumption of narcotic drugs, blood and urine samples of the accused are received and subjected to screening and confirmatory tests.

Screening assays followed by confirmatory instrumental analysis Chain‑of‑custody and court‑ready documentation
