The Troubleshooting and Maintenance Guide for

This fourth edition of the classic guide for every user of gas chromatographic instrumentation is now updated to include such new topics as fast GC using narrow, short columns, electronic pressure control, and basic aspects of quantitative gas chromatography.The author shares his many years of experience in technical support for gas chromatography users, addressing the most common problems, questions and misconceptions in capillary gas chromatography. He structures and presents the material in a concise and practical manner, suitable even for the most inexperienced user without any detailed knowledge of chemistry or chromatography.For lab technicians in chemistry, analytical, food, medicinal and environmental chemists, pharmaceutists.

Dean Rood is Senior Applications Chemist with the major instrument manufacturer Agilent.
