Which inert gas is used in chromatography?
- A Ar
- B Ne
- C \(\mathrm{Kr}\)
- D He
Answer & Solution
Correct Answer
(A) Ar
Step-by-step Solution
Detailed explanation
Carrier gas is an inert gas used to carry samples. Helium \(\mathrm{(He)}\), nitrogen \(\mathrm{(N_2)}\), hydrogen \(\mathrm{(H_2)}\), and argon \(\mathrm{(Ar)}\) are often used. Helium and nitrogen are most commonly used and the use of helium is desirable when using a capillary column.
