E21-25: GC/MS Fundamentals for Operators

One-Day Course 
Tuesday, November 16; 8:30am – 5:00pm

Dr. Matthew S Klee, XO Associates LLC, Northborough, MA

This course is oriented to GC/MS operators who have not had any formal training in gas chromatography and/or mass spectrometry. Fundamental concepts are introduced and explained in the context of how the instruments are used and results generated.

This course is oriented toward occasional users as well as newly assigned users of GC/MS systems who have not had recent training in the area. Fundamental physical and mechanical processes will be presented in a way that will help GC/MS users be more comfortable and effective in operating and maintaining their instruments.
