Gain practical laboratory experience in gas chromatography. The course provides the fundamentals to understand the techniques and instrumentation involved in this powerful analytical tool.
This course is designed for beginners and intermediate-level practitioners who want practical laboratory experience in gas chromatography (GC).
The lectures—supplemented by problem sets, slides, and video presentations—provide the fundamentals needed to understand the technique and instrumentation involved in this powerful analytical tool. In this class, you will master the fundamentals of GC, participate in five hands-on laboratory sessions, perform reference and literature searches, and learn specialized techniques based on your specific interests.
Beginners and intermediate-level practitioners in gas chromatography who want practical laboratory experience.
No previous experience in gas chromatography is required for the course.
