Gas Chromatography
World events such as the Gulf Oil Spill only serve to remind us how important the techniques of GC and GC-MS are. With testing of the food chain largely accomplished with these techniques, GC and GC-MS are once again in the spotlight. Joining us for this discussion on gas chromatography this month are Eric Phillips of Thermo Fisher Scientific and Ngoc Nguyen of Phenomenex.

New XSelect Prep Columns. New Chemistries. Higher loading.
The new Charged Surface Hybrid (CSH) prep columns offer the greatest benefits to purification scientists including fast screening using ACQUITY UPLC CSH columns that can be directly scaled to XSelect Prep Columns. These preparative columns, offered in Optimum Bed Density Technology (OBD), will provide:
• high loadability of bases using simple low or high pH mobile phases
• long, predictable column lifetimes
• widest selectivity range in CSH C18, CSH Fluoro-Phenyl, CSH Phenyl-Hexyl stationary phases

Effect of Temperature on Elution Order in GC
When analyzing via GC, the desired separation can sometimes be achieved by changing the oven program. This technique takes two properties into account: a compound’s boiling point and its ability to interact with the stationary phase.
