The tests which usually help in determine the Gunshot residue in the clothing's except:: (A) Modified Greiss test, (B) Sodium rhodizonate reaction, (C) Energy dispersive X-ray (EDX), (D) Vaccum metal deposition method
Answer is D. Clothing may be tested for presence of GSR Modified Greiss test(specific for nitrites):- - It uses chemicals (alpha-naphthol) to produce visual display of GSR pattern and density of paicles. Sodium rhodizonate reaction - detects lead from primer or bullet wipe. Energy dispersive X-ray (EDX) - detects barium, antimony, lead and copper around the entry wound in clothing - It can be used to determine the range of fire. Vaccum metal deposition method- used for fingerprint development.
