Gas Chromatography: Carrier Gases, Capillary Techniques


Meeting Reports

Session 1650, Room 119B, 3:00 p.m.

This Wednesday afternoon session will be presided over by Susan S. Marine of Miami University Middletown.

The first presentation is titled “Optimizing and Improving Carrier Gas Systems Enables You to Reduce Your Gas Usage” and will be given by Reginald J. Bartram of Bartram Consulting. Bartram will discuss the supply shortage of helium and the option of switching to hydrogen as a carrier gas.

The next presentation in the session is titled “Unintended Consequences with Conversion to Hydrogen Carrier in Gas Chromatography” and will be given by Randall Bramston-Cook of Lotus Consulting. The presentation will focus on the effects on the chromatographic process resulting from a switch to hydrogen carrier gas, including performance changes, calibration of pneumatic components, detector compatibility, and alterations in regulatory protocols.

Kory Kelly of Phenomenex will then present a talk titled “Using Large Volume Injection (LVI) on Conventional Split/Splitless Inlets to Improve Sensitivity or Reduce Sample Preparation.” Kelly will describe the requirements and limitations of large-volume injection using traditional split–splitless inlets. The effects of liner selection, solvent selection, column configuration, and oven temperatures will be discussed.

The session’s final presentation will be given by Ony Rabetsimamanga of GDF SUEZ – CRIGEN and is titled “How to Manage Helium Shortage? Let’s Use Hydrogen to Measure THT in Natural Gas with Micro-Chromatographs.” The talk will discuss the use of hydrogen as a carrier gas with a micro-GC system. Argon and nitrogen were also tested.
