Restek is pleased to partner with LCGC International for this educational opportunity.

While there are numerous ways to increase the speed of analysis, the low-pressure gas chromatography technique is a unique way of tackling faster run times while reducing helium usage. LPGC uses short, wide, and medium bore columns—rather than a short, narrow one—with the power of the mass spectrometer to decrease analysis times. Coupling this type of analytical column with a narrow guard column that acts as a restrictor allows normal head pressure at the inlet, while the analytical column is operated under near-vacuum conditions. Because of shorter run times and lower flow rates, LPGC can lead to an 80% reduction in helium usage compared to conventional GC-MS using a 30 m column and make run times up to four times faster.

  • Learn how LPGC works and how to use it for analyses.
  • Understand how the technique can reduce run times and carrier gas usage.
  • See the limitations of the technique and when LPGC might not be appropriate.
