Why could chromatography be used in investigating the crime?
Chromatography could be used in investigating a crime because it can separate and analyze complex mixtures of substances, such as drugs, poisons, or chemicals found at a crime scene. By identifying and comparing different compounds in samples, chromatography can provide valuable evidence to link suspects, victims, or locations to a crime.
How chromatography is used in CSI?
Chromatography is used in CSI to separate and analyze the components of complex mixtures like blood, drugs, and fibers found at crime scenes. By identifying and comparing the unique chemical fingerprints of substances, chromatography helps forensic scientists link evidence to suspects, determine timelines, and solve crimes. Different types of chromatography, such as gas chromatography and liquid chromatography, can be utilized depending on the nature of the sample being analyzed.
Do Crime Scene Investigators use Chromatography?
Yes, Crime Scene Investigators use chromatography to analyze and identify substances found at crime scenes. Chromatography helps separate and detect chemical compounds in a sample, such as drugs or accelerants, aiding in the investigation and solving of crimes.
Which chromatographic process would be least likely to be utilized in the crime lab?
Size-exclusion chromatography would be least likely to be utilized in the crime lab compared to other types such as gas chromatography or liquid chromatography. Size-exclusion chromatography separates molecules based on their size, making it less commonly used for the complex mixture analysis typically required in forensic investigations.
How do you use chromatography in everyday life eg forensic science and Csi crime scene Inveatigation?
Chromatography is used in forensic science to separate and analyze complex mixtures of compounds found in samples such as blood, drugs, or fibers collected from crime scenes. In CSI investigations, chromatography helps identify unknown substances, compare samples, and provide evidence for solving crimes, through techniques like gas chromatography and high-performance liquid chromatography.

How can chromatagraphy be used in crime scenes?
It is a valuable tool used by chemists to identify chemical components or biological materials that might be clues to a crime. Chromatography is a way of separating chemicals from one another. One of those chemicals might shed light on the crime or provide investigators with leads or answers useful in solving the crime. Chromatography was developed by a Russian botanist in 1906 to study plant pigments. Then chemists realized it was an excellent way to study all kinds of complex mixtures. Forensic science jumped all over that one in order to identify unknown samples from a crime scene! Win-win!
How is blood used to solve a crime?
Blood can be analyzed at a crime scene to determine the blood type of the individual, which can help exclude or include suspects. DNA analysis from blood samples can help establish a match between the blood found at the crime scene and a suspect. Blood spatter patterns can also provide clues about the events that took place during a crime.
Do Crime Scene Investigators use Chromatography?
Yes, Crime Scene Investigators use chromatography to analyze and identify substances found at crime scenes. Chromatography helps separate and detect chemical compounds in a sample, such as drugs or accelerants, aiding in the investigation and solving of crimes.
Why do Forensic scientists sometimes use chromatography to investigate paints left at a crime scene and what could this tell them?
Forensic scientists use chromatography to separate the components of paint samples, which can reveal the chemical composition of the paint. This information can help match paint from a crime scene to a particular source, such as a suspect's car, or to determine if different paint samples originated from the same source.
Which chromatographic process would be least likely to be utilized in the crime lab?
Size-exclusion chromatography would be least likely to be utilized in the crime lab compared to other types such as gas chromatography or liquid chromatography. Size-exclusion chromatography separates molecules based on their size, making it less commonly used for the complex mixture analysis typically required in forensic investigations.
What evidence can be used for DNA fingerprinting at a crime scene?
DNA evidence from blood, hair, saliva, or other bodily fluids found at the crime scene can be used for DNA fingerprinting. This evidence is compared to the DNA profiles of suspects to determine if a match exists, helping to identify or exclude individuals involved in the crime.
What aspects of the crime scene as observed by al Dewey examining photographs foreshadow the eventual capture of the suspects?
Al Dewey observes the bloodstains, footprints, and other evidence at the crime scene, which provide clues for tracking down the suspects. The bloodstains can be analyzed for DNA evidence, footprints can be matched with suspects' shoes, and other trace evidence can link the suspects to the scene, ultimately aiding in their capture.
Who would use chromatography?
Crime labs use chromatography to identify unknown substances by breaking the two substances down into their constitute parts, and comparing them to see if they are a match.
Who interrogates a suspect at a crime scene?
suspects are usually not interrogated at the crime scene. They are taken into a room where they can be video taped for safety and court reasons
