Chromatography is used in blood to determine whether it is contaminated with alcohol and things like that. It can be also used to find out if cocaine etc. is in your urine and lead in water. This uses a colour chart to see what chemicals have been used and added up make a compound, then you can find out that it is alcohol, lead etc.

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 is the general purpose of candy chromatography?
The general purpose of candy chromatography is to separate and analyze the different components present in a mixture of colored dyes used in candies. By using a chromatography technique, it is possible to identify and quantify the substances that contribute to the color of the candies.
What are the controlled and manipulated variables in a plan and design paper chromatography lab?
In a paper chromatography lab, the manipulated variable is typically the solvent used for the chromatography process, as different solvents can affect the separation of components in the sample. The controlled variables include factors such as the type of paper, the amount of sample applied, the temperature, and the duration of the experiment, as these can influence the results and must remain consistent to ensure valid comparisons.
What are the variables in a plan and design paper chromatography lab?
Key variables in a paper chromatography lab include the type of paper used, the solvent system composition, the distance traveled by each compound, the time of development, and the temperature at which the experiment is conducted. These variables can affect the separation efficiency and resolution of the components being analyzed in the mixture.
How can a crime lab use paper chromatography to determine if lipstick at a crime scene match the suspects?
A crime lab can use paper chromatography to analyze the pigments and chemical components of lipstick found at a crime scene. By applying a small sample of the lipstick onto chromatography paper and using a solvent to separate the components, the lab can create a distinct profile of the lipstick's ingredients. This profile can then be compared to samples from the suspect's lipstick; if the patterns and colors match closely, it can support the case that the suspect's lipstick was present at the crime scene. This method is valuable for its ability to reveal subtle differences in composition that may be unique to specific brands or batches of lipstick.

What is the purpose of slinky lab?
The purpose of the slinky lab is to see how waves reflect, refract, and lose and gain energy.
How do you do chromatography?
I f you want to observe this theory in simple way ,you can observe it through using filter paper has ink on it and leave it in water ,after time when the water get evaporated you will observe that the ink was separated and this is a simple chromatography. And this is core concept for chromatography. Saleh Qahtani Lab Tech

What is the purpose of using silica gel in chromatography?
Silica gel is used in chromatography to separate and analyze different compounds in a mixture based on their interactions with the silica gel. The purpose is to achieve a more accurate and efficient separation of the components in the mixture.
What is the purpose of lab safety?
The purpose of lab safety is to keep you safe because some experiments(labs) have dangerous chemicals that could harm you.
