Question
Chapter 22, Problem 22.23P
Interpretation Introduction
Interpretation:
Reason behind the use of splitless injection with purge and trap sample preparation has to be explained.
Concept Introduction:
Splitless injection is very important injection technique for trace analysis in highly diluted sample. Spiltless injection has narrow injection band with solvent refocusing and cold trapping. By this injection method, loss of analyte can be prevented at the time of injection it into column.
