Chromatography is an analytical method to separate a mixture into different components based on their chemical properties. In one form of chromatography, a liquid or gaseous mixture is passed through a tube containing a "stationary phase" (column chromatography). For gasses, this usually means coating the walls of a thin tube with the stationary phase. For liquids, it usually involves something that looks more like sand or powder. If the composition of the stationary phase is chosen correctly, the different components in the mixture will absorb and desorb from the stationary phase at different rates. Some will pass through quickly because they don't absorb very well into the stationary phase and desorb quickly while others pass through slowly as they get absorbed easily and desorb slowly. As a consequence, the different components come out the other end at different times. The amount of each is determined by some kind of detector.
A second kind of chromatography is a bit like the liquid chromatography described above, except drops of the mixture are placed at one end of a sheet of paper or a sheet of glass coated with a stationary phase. A solvent is then applied to one end of the sheet and slowly carries the mixture with it to the other end of the sheet. the mixture gets separated into its different components with some moving only a short distance from the beginning end and others moving further along the sheet. At the end, the sheet winds up with stripes of the different components at different locations.
In forensics, chromatography can be used to determine what is in a mixture. When people go in for drug tests, their urine may be analyzed using chromatography to determine if they have drugs or drug byproducts in their urine. In forensic pathology, a sample may be analyzed to determine what chemicals are present in the dead body and possibly indicate if there is a poisonous substance present that may have killed them, or whether they were on drugs or drunk at the time of their death. It may also be used to analyze samples taken from crime scenes to find out if any unusual substances are present that might indicate where something came from or where someone may have been prior to entering the crime scene. At airports it can be used to detect minute traces of explosives.
Chromatography is used in forensic science to separate and analyze compounds found in substances like drugs, blood, and fibers. By separating the components of a sample, analysts can identify and compare substances based on their chemical properties and determine if they match those found at a crime scene. This technique is crucial for identifying illicit substances, identifying compounds in trace evidence, and determining the origin of materials.
chromatography is used in forensics to match DNA or any other substance or compound.
They take items from the scene of the crime and make a small smaple out of it. They then put it through chromatopgrahy to see if they can find a DNA match and catch the criminal.
Chromatography can be used in a crime scene investigation to narrow down suspect who owned the type of pen or marker that was found at a crime scene.
Chromatography is a technique for chemical analysis. If an unknown chemical is present at a crime scene, it may be useful to identify it.

How can ink chromatography be used in forensic science?
Ink chromatography can be used in forensic science to analyze pen inks and determine if two or more inks are chemically similar, aiding in forgery detection. By separating the ink components, analysts can compare the ink profiles from different sources to provide evidence in cases involving counterfeiting or document fraud.
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 is chromatography used?
Chromatography is a technique used to separate and identify individual components within a mixture. It is commonly used in science, forensics, and biochemistry to analyze substances such as drugs, proteins, and pollutants. By exploiting differences in the way different substances interact with a stationary phase and a mobile phase, chromatography allows for precise separation and analysis of complex mixtures.
How is chromatography used to catch criminals?
Chromatography is used in forensic science to analyze and match substances found at crime scenes, such as drugs, explosives, or biological samples like blood or DNA. By separating and identifying these substances based on their unique chemical characteristics, chromatography can provide valuable evidence linking a suspect to a crime.
Why is chromotragraphy important?
Chromatography is important because it is a versatile technique used for separating and analyzing mixtures of substances. It is widely used in various industries such as pharmaceutical, environmental, food and beverage, and forensic science for quality control, research, and analysis purposes. Chromatography helps in identifying compounds present in a mixture, measuring their concentration, and purifying substances for further use.

How are skeletons used in forensic science?
They're used in forensic science to help you learn about specific parts ofthe body. they may also be used by helping you learn about bones,muscles and joints.
What's the difference between a forensic scientist and a forensic science technician?
A forensic scientist is typically involved in analyzing evidence in a laboratory setting and providing expert testimony, while a forensic science technician is usually responsible for collecting and processing evidence at crime scenes. Forensic scientists often have more specialized training and expertise in a particular scientific field, while forensic science technicians have more general knowledge of crime scene investigation techniques.
