About this mock
UGC-NET Forensic Science Unit II drill on atomic spectroscopy in forensic casework. Medium-band questions cover atomic absorption (flame and graphite furnace), atomic emission and ICP-OES, plus the elemental analysis of gunshot residue, heavy-metal poisoning samples, soils and glass. Items test instrument components, background-correction choice, interference handling, sample digestion, and the comparative role of AAS, ICP-OES, ICP-MS and SEM-EDX in real laboratory workflows, with citations from Skoog, ENFSI, ASTM and Indian CFSL practice.
