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.

Two industries that use chromatography are pharmaceuticals and environmental testing. In pharmaceuticals, chromatography is used for drug development and quality control. In environmental testing, chromatography helps analyze pollutants in air, water, and soil.
Chemists use liquid chromatography a complex of substances. They can use chromatography to analyze drugs and also test blood and urine samples. People use it to separate and purify different substances and chromatography can detect the presence of drugs in a person's blood.
Historians use chromatography to trace evidence and find out more about events in the past that might have occurred. For example if there was a letter written by a famous monarch or leader of which a historian would want to know more about, they would check the ink of the pen which answers to them of what pen they used, who had written it and how old the pen was when they used it and this answer can simply be found just by the method of chromatography which separates soluble substances from insoluble subtances.
If you like science Paper Chromatography is something to look into. You can take Chemistry classes to find out different ideas on how to use Paper Chromatography.
Chromatography can help separate individual components of a complex mixtures AND quantify them with the use of a calibration curve.
Instead of chromatography paper, you can use materials like coffee filters, filter paper, or even paper towels for paper chromatography tests. These alternative materials can absorb the solvent and help separate the components of a mixture based on their solubility and molecular properties, similar to chromatography paper.
to measure time
I'd probably use chromatography, given the option. A GC/MS instrument would do nicely.
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.
