Question
Chapter 27, Problem 27.3QAP
Interpretation Introduction
Interpretation:
The phenomenon of temperature programming in GC and the reason for it’s frequent use is to be stated.
Concept introduction:
In the temperature programming method, the temperature of the column is continuously raised at a predefined rate which varies as function of time. This technique is commonly used for the analysis of mixtures with a wide range of boiling points.
