Understanding Gas Chromatography: Techniques and Recent Advances
In this lecture, we review key concepts in gas chromatography (GC), focusing on both traditional and advanced techniques. Highlights include the recent quiz results, showing an average score of 49 (82%), surpassing past performances. We will cover additional GC topics such as liquid chromatography basics, stationary phases, and the principles of comprehensive two-dimensional GC, also known as GC x GC. Relevant literature from Crimi & Snow will be discussed, alongside recent reviews on GC applications, providing insights into modern chromatographic practices.

1. Chem. 230 10/19 Lecture
2. Announcements Quiz 2 Results
Ave = 49 (82%)
Better than 2 years ago and last quiz
Results better than I expected
3. Announcements What we are covering today?
Additional Topics in GC (Section 7.6)
Liquid Chromatography Overview (Section 8.1)
Stationary Phases (Section 8.2)
4. GC Other Topics Comprehensive 2 Dimensional GC (or GC x GC) See Chapter 15, section 1 Also materials from Crimi and Snow, LCGC North America (2008), 26, 62-70. Another recent review (focused on applications) is Adahchour et al., J. Chromatogr. (2008), 1186, 67-108. a simple TLC example of a 2 dimensional separation: Separation first in 1 dimension (e.g. hexane) Then separation in 2nd dimension (using different solvent say benzene) GC x GC is most common multi-dimensional instrumental method
