You run a chromatography of inks belonging to three crime suspects and from a ransom note. the inks resolve into the following numbers of spots: suspect a=2, suspect b=4, suspect c=3, note=5. which suspect would you most likely bring in for questioning

No subject.

Explanation:

Hello,

At first, let's remember that chromatography is the available technique for separating mixtures into its components based on the principle of stationary and mobile phases. Such technique is also used to separate inks, thus, the stationary phase is paper and the mobile phase is solvent/sample. The ink on the pen is a mixture of several dyes which can be separated and subsequently shown in several spots.

In this question, it is stated that the ink from the notes shows 5 spots while the ink from the suspect's pen is only 2 spots (suspect A), 4 spots (suspect B) and 3 spots (suspect C).

Thus, by considering the aforementioned fact, one concludes that there is no match, but that approaches the number 5 spots of the ink note is suspect B with 4 spots.

Best regards.
