Forensic Tools and Techniques

Forensic science has great importance in law enforcement departments because a combination of different sciences like chemistry, biology, and physics is applied for the collection and interpretation of physical evidence. In the modern era, forensic science is getting more popularity because of its involvement in different real-life cases, television shows, movies, and books. Forensic scientists analyze the crime scene with the help of various tools and techniques for the collection of crucial evidence to solve criminal cases. The role of MJS Designs is unforgettable in the field of forensic science.

This applied science is connected to the examination of the dead body to collect important clues and pieces of evidence. Forensic scientists can identify a stranger’s dead body with the help of the DNA test. Differential scanning calorimeter is an essential tool used by forensic scientists.

Collection and Analysis of Evidence

Forensic science always proves helpful for crime investigation department because forensic doctors analyze all evidence collected by the copes of the crime investigation department to find a useful clue. Differential Scanning Calorimetry plays a vital role because it helps in the performance of different tests.

Evidence can be anything like a fingerprint, shoe mark, plant fiber, hair, the residue of a gunshot, tire tracks, broken nail, etc. Specifically designed tools like brushes, combs, vacuum cleaner, chemicals, taps, powder, gels, sprays, scissors, etc. are used to collect the evidence from the crime scene.

Close Up Photographs

Usually, the evidence is divided into two groups called organic and inorganic. It is challenging to clearly distinct organic versus inorganic material, but materials with carbon contents can be categorized as an organic compound. Synthetic fibers are also known as organic materials. Forensic work starts with the examination of photographs taken on the crime scene.

Tire marks and footprints are examined through photographs. Textile material proves helpful to identify suspected persons. Clear pictures of fabric can help you in the investigation as you can know about cloth manufacturers for further investigation. Use forensic tools with pcb layout. The PCB cad layout can scale forensic tools efficiently.

Microscopes and Thermal Analysis

It is important to check the soil of the crime scene and the soil found in the shoes and clothes of the dead body. The thermomechanical analyzer is good for thermogravimetric analysis to know about the origin of the deceased or suspected person.

Different types of microscopes are also required for the analysis of evidence according to the nature of the sample. To get X-ray images of specimens, SEM “Scanning Electron Microscope” is being used. It is a special microscope used for the analysis of hard but dry material like bones and wood. Stereo microscopes are useful to analyze drugs, while comparison microscopes are useful to examine bullets and cartridges.

DNA Tests

Blood testing kits are an essential part of forensic tools because these kits are suitable to check the blood type. A chemical called “Benzidine” is used in water solution to turn color of blood scrapings pink, and an antigen is also used to check the blood type. Different pharmacology and chemistry tools are helpful to trace chemicals, poisons, or drugs in the stomach, hair, or saliva. A hair sample, saliva, skin pieces, or blood sample is required to perform a DNA test of a specific person.
