In a bank robbery investigation, paper chromatography can be used to analyze ink from notes or other documents left behind. By separating the components of the ink, forensic scientists can identify its chemical composition and potentially match it to specific brands or batches of ink used in banknotes. This can help link the robbery to a suspect if they possess similar ink or if it matches ink found at their location. Ultimately, it serves as a crucial tool in tracing evidence and building a case against the perpetrators.

Which dyes adhere best to chromatography paper?
Dyes that are more polar tend to adhere better to chromatography paper because they interact more strongly with the cellulose fibers in the paper. Therefore, water-soluble dyes like food coloring or ink tend to work well for paper chromatography.
How does chromatography work to separate particles of ink?
Chromatography works to separate particles of ink by exploiting differences in solubility between the ink components and the mobile phase (solvent). As the mobile phase moves through the stationary phase (usually a paper or column), it carries the ink components at different rates based on their solubility. This differential movement results in separation of the ink particles into distinct bands or spots on the chromatography paper.
Disadvantages of using paper chromatography?
TLC has following advantages over paper chromatography: greater speed greater sensitivity for many substances than paper Small sample requirement Usually sharper preparation Different kind of reagents can be applied without damaging the plate
What pen works best with chromatography?
A fine-tipped marker or pen works best for chromatography as it can produce clear and precise lines on the paper, allowing for accurate separation of the pigments. It is important to use a water-soluble ink that will dissolve in the solvent used for the chromatography process.
Why would ethanol work but not with water when using felt tip pens in an chromatography experiment?
Ethanol would work because it is alcohol-induced, therefore, it is stronger than water.

What solvent can be used for food colorings when doing paper chromatography?
Water should work well as food colourings are usually water soluble.
Does bank robbery show up in county criminal files?
Yes. Bank robberies do show up. It is a criminal offense. They will make sure you cant work in one. I can assure you that.
What determines the distance a pigment moves up the paper?
The distance a pigment travels up the paper in paper chromatography is determined by its solubility in the solvent being used, its molecular size, and its attraction to the paper. Pigments that are more soluble and smaller in size tend to move further up the paper, while those with stronger interactions with the paper tend to stay closer to the origin.

What do I do if I did not receive a federal tax form 1099 from my bank?
Contact your bank directly. They should be able to provide you with the needed paper work.
Who is the redhead in the LifeLock bank robbery commercial?
The redhead in the LifeLock bank robbery commercial is actress and comedian, Christina Pickles. She is known for her work in television and film, including roles on shows like "St. Elsewhere" and "The Best Man." In the commercial, she humorously portrays a character involved in a heist, highlighting the importance of identity theft protection.
What causes highway robbery?
highway robbery is caused by unemployment in the country and other times laziness to work.

Who investigates bank robberies?
Bank robberies are typically investigated by local law enforcement agencies, such as the police department or the FBI, depending on the severity of the crime. These agencies work together to gather evidence, interview witnesses, and track down suspects in order to solve the robbery and bring the perpetrators to justice.
How do you make money in Doodle God?
You can't make a bank in doodle god. Plus if you could you would need money+human=bank.
