Study Notes
Equipment Used in Forensic Examination
-
HPLC (High Powered Liquid Chromatography)
- Essential for determining both the identity and concentration of compounds.
- Capable of separating volatile and non-volatile components within samples.
-
Ultra-violet Spectrophotometer
- Provides both qualitative and quantitative analysis of organic compounds.
- Utilizes UV light to assess absorbance and concentration levels.
-
EMIT (Enzyme Multiple Immuno Assay Technique)
- Specializes in screening urine samples for drug abuse.
- Employs enzyme reactions to detect specific analytes in biological fluids.
-
SEM (Scanning Electron Microscope)
- Facilitates the physical identification of questioned specimens.
- Offers high-resolution imaging by scanning samples with focused electron beams.
-
FTIR (Fourier Transform Infrared Spectroscopy)
- Used to identify pure organic substances by measuring their infrared absorption.
- Effective in providing molecular fingerprinting of compounds for forensic analysis.
