This section includes the study material and various researches about a particular subject related to forensics that helps in investigations.
The person who studies toxicology along with its medicolegal aspects is known as a Forensic Toxicologist. Forensic toxicologists are treated as experts in the court where they represent their opinion based on the analytical results.
UV-Visible spectroscopy is an analytical technique that identifies a component that shows absorption or reflectance of ultraviolet(UV) and visible electromagnetic radiations under the range from 200-800 nanometers (UV range 200-400nm and Visible range 400-800nm).
Harrison-Gilroy’s test is a method of detecting metallic constituents in the firearm discharge or gunshot residue(GSR). This test is specific for the presence of barium, lead, and antimony in the discharge.
Acne and dark spots may damage the self-esteem and mental health of a person. While time may cure physical wounds, emotional scars may last a lifetime. Acne and black spots on the skin may make someone feel horrible about themselves, which may subsequently lead to worry, depression, and isolation. Knowing Read more…
AES is an analytical technique that uses the emitted radiations for the determination of metallic compounds in a given sample.
Henry’s classification system is the most accepted method for classifying fingerprints. It is widely used in today’s modern fingerprint examination methods.
When x-rays are incident on a crystalline substance, the electrons of atoms of the substance become small oscillators and emit electromagnetic radiations in all directions at the same frequency as that of incident x-rays. This is called x-ray diffraction.
Mass spectrometry is a quantitative analytical technique used to determine the components present in a compound with their structure and chemical properties.
Soil is one of the potential trace evidence, found at almost every crime scene. Since it is present all over the landmass, therefore it is prevalent in every crime scene, either in small amounts or bulk quantities.
The pressure applied on the writing surface, especially the paper while writing, results in indentation marks on the paper and subsequent paper sheets placed beneath the writing paper, and this is called indented writing.
Brain mapping is a process that measures and studies the changes in the electrical field of potentials produced by the sum of the neuronal activities in the brain of an individual person.
NAA- Neutron Activation Analysis, a radioactive analytical technique applied for the qualitative and quantitative analysis of a substance.
Atomic Absorption Spectroscopy(AAS) is a quantitative analytical elemental technique that provides the total metal content of the sample and is almost independent of the molecular form of metal in the liquid sample. It analyzes the concentration of elements in a liquid sample based on energy absorbed from certain wavelengths of Read more…
The invention of the microscope has been a boon in the scientific field which allowed scientists to visualize things or matter or objects which are not visible to the naked eye. The first microscope came into existence with the invention of the early microscope, by a Dutch spectacle maker Zacharias Read more…
Scanning Electron Microscope (SEM) is a type of electron microscope that produces a three-dimensional image of a microscopic object. As the name suggests a microscope forms images by scanning the surface of the object with the help of a focused beam of electrons. SEM was first developed in 1937 with Read more…
