Pens were made due to demands of users for better writing. Pen is of two types in which first is ballpoint pen and second is ink pen. A ballpoint pen is a writing instrument that dispenses ink via a metallic sphere at the pen's tip but its ink cannot refill. Ink pen is refill again and again using ink from ink pot.This ink is manufactured by combining a variety of chemicals, which are then mixed together and heated or cooled in order to facilitate the necessary chemical combinations.
Fingerprint ink is a specialized ink used in fingerprinting to create a clear and accurate impression of an individual's fingerprint. It is typically a non-toxic, fast-drying ink that is applied to the finger and then transferred onto paper or a digital scanner to capture the unique pattern of ridges and valleys in the fingerprint.
To collect a fingerprint, you typically need a clean surface to place the finger on, fingerprint powder or ink to make the fingerprint visible, a brush or roller to apply the powder or ink, and fingerprint lifting tape to transfer the print to a card or paper for preservation and analysis.
A chromatogram is like a chemical fingerprint because a fingerprint is diffrent for every single person in the world and to indicate who is who we use fingerprints, for chromatography its a bit diffrent because you can have more than 2 types of the same thing. For example if someone has been killed & they found a little ink next ti the person, they would collect the ink. Then they would find the few people they think are the suspects. They would take a bit of each suspects' ink and then they would use chromatography to indicate who did it (who has the same ink as the murdurer ). So basically a chromatogram is like a chemical fingerprint because they both indicate who is who or who did what.
