Restek Corporation and the Association of Public Health Laboratories (APHL) have embarked on a joint venture to present educational programs to clinical and public health laboratories. Programs are based on current Restek seminars and will help managers, supervisors and analysts improve the quality and efficiency of their laboratories.

Each of the modules are recorded and available for review or training of new staff. Both beginning and advanced chromatographers will benefit from these dynamic, in-depth sessions.

All of the live webcasts will take place 1:00–2:00 PM ET.
The archived webcasts will be available until June 14, 2012
Module 1: Introduction and Chemistry of Headspace Analyses (September 7, 2011)
A solid review of headspace processes, terminology and operations. Includes a discussion on headspace theory, definitions, operational considerations and quality measures associated with this important technique.

Module 2: Sample Preparation and Handling (October 5, 2011)
Understanding the steps required to prepare a suitable headspace sample prior to analysis is vital for obtaining optimal headspace results. Sample vial geometry, types of vial and seal hardware and sample preparation technique can all affect peak response. Optimization of the vial / sample system and other unique sample preparation techniques will be considered.

Module 3: GC Principles and Modes of Operation (November 2, 2011)
This unit provides a comprehensive examination of sample introduction techniques, autosampler interfaces for GC, and GC instrument set up. Critical factors that affect chromatographic separations including capillary column chemistry as well as GC detector theory and operation will also be considered.

Module 4: Method Development (November 30, 2011)
Knowing how to approach method development efficiently can save time and reduce headaches. Gain critical skills and insight from experienced chemists. Follow along as we walk you through the rocess of identifying analytical and separation goals, select preliminary conditions, optimize parameters and validate your final method.

Module 5: Maintenance and Troubleshooting (December 14, 2011)
Performing routine maintenance on your GC and Headspace instruments is crucial for obtaining the best chromatographic results. Learn the keys to keeping your instruments operating at peak performance. Develop your own approach to solving instrument performance problems as we work through several troubleshooting exercises.

At the conclusion of this program, the participants will be able to:
  • Discuss headspace theory and practice, selecting proper sampling techniques and optimize headspace methods as applied to a wide variety of clinical and environmental samples.
  • Outline the steps necessary for proper headspace method development.
  • Summarize the principles and modes of operation of gas chromatographic systems when performing headspace analysis.
All speakers are from Restek Corporation, Bellefonte, PA:
Module 1: Scott Grossman
Module 2: Scott Grossman
Module 3: Rick Morehead
Module 4: Amanda Rigdon
Module 5: Chris English

Who Should Attend:
This intermediate-level program is appropriate for managers, supervisors, and analysts working in public health, clinical, and environmental laboratories.
