In: Chemistry
Part 1) Solvent trapping is used for
a) analysis of trace components.
b) analysis of high-boiling major components.
c) analysis of low-boiling major components.
Part 2) Open tubular columns of less than 0.53 mm in diameter:
a) cannot be used for on-column injection of analyte with a standard injection needle.
b) do not give resolution as good as that of wider columns.
c) are excellent when used with thermal conductivity detectors.
For Question 1 :
Option b is correct : solvent trapping is used for high boiling major components.
For Question 2 :
Option b is correct : open tubular columns less than 0.53 mm diameter does not give good resolution than wider columns.
