Presentation (5).pptx advantage of analytical tools
- 1. Advantage of analytical tools The benefits of analytical tools in forensic science include: • Improved accuracy:Analytical tools provide precise and reliable results, reducing the risk of human error • Enhanced sensitivity: Analytical tools can detect trace evidence and small amounts of DNA, leading to more successful investigations. • Increased efficiency: Analytical tools automate many processes, saving time and resources. • Objective results: Analytical tools provide objective results, reducing the influence of personal bias • Faster analysis: Analytical tools enable rapid analysis, accelerating the investigation process
- 2. ADVANTAGES OF ANALYTICAL TOOLS IN FORENSIC SCIENCE • Better evidence preservation: Analytical tools help preserve evidence integrity, ensuring its admissibility in court. • Enhanced crime scene analysis: Analytical tools aid in reconstructing crime scenes and understanding criminal behavior. • Improved suspect identification: Analytical tools facilitate DNA profiling, leading to faster suspect identification. • Increased conviction rates: Analytical tools provide strong evidence, contributing to higher conviction rates. • Cost-effective: Analytical tools reduce the need for repetitive testing and manual analysis, saving resources. • Advanced DNA analysis: Analytical tools enable advanced DNA analysis, including familial searching and phenotyping. •
- 3. ADVANTAGE OF ANALYTICAL TOOLS IN FORENSIC SCIENCE • Digital evidence analysis: Analytical tools aid in Analyzing digital DNA analysis including familial searching and phenotyping. • Toxicology analysis: Analytical tools detect drugs and poisons, helping investigate drug-related crimes and overdoses. • Ballistics analysis: Analytical tools compare bullet markings, linking crimes and suspects. • Forensic comparison: Analytical tools compare evidence from different sources, identifying connections between crimes.These benefits demonstrate how analytical tools have revolutionized forensic science, enhancing investigations and leading to more successful prosecutions.
- 4. DISADVANTAGES OF ANALYTICAL TOOLS IN FORENSIC SCIENCE Here are the disadvantages of analytical tools in forensic science: • Cost: Analytical tools can be expensive, and maintaining and upgrading them can be costly. • Complexity: Some analytical tools require specialized training and expertise to operate and interpret results. • Limited availability: Some advanced analytical tools may not be widely available or accessible to all forensic laboratories. • Sample contamination: Analytical tools can potentially contaminate samples, leading to false results. • Instrumental bias: Analytical tools can introduce bias and errors if not properly calibrated or maintained. • Interference: Analytical tools can be susceptible to interference from environmental factors or other substances. • Limited sensitivity: Some analytical tools may not be sensitive enough to detect trace evidence or small amounts of DNA
