Height equivalent to theoretical plate (HETP) in gas liquid chromatography depends Significantly on which of the following?(A) Temperature of column(B) Velocity of carrier gas(C) Packing of column(D) Column material
(a)A, B and C
(b)C and D
(c)B, C and D
(d)A and C
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
By the van Deemter equation, HETP depends on carrier-gas velocity, column packing (particle size, eddy diffusion) and temperature (diffusion coefficients, mass transfer). A, B and C (a).
