Central Forensic Science Laboratory, Ministry of Home Affairs, Govt. of India, Plot No. 2, Dakshin Marg, Sector-36A, Chandigarh.
In a case of poisoning a small quantity of gastric lavage was made available for analysis and defection of poison. Keeping in view limited amount of sample available and indications from postmortem examination, only targeted analysis was carried out cautiously. Exhibit was containing pesticide beyond the limits of conclusive identification by conventional methods. On faint indication of poison to be carbamate pesticides or phenolic compounds and to avoid contamination of GC-MS, sample was purified by TLC method. The presence of just three ions allowed the poison to be identified again by processing and analyzing the standard by the same method. The poison responsible to kill the lady could be identified in spite of limitatiom of availability of samples and application of conventional method.
