Convert to Hydrogen as a Carrier Gas
The global shortage of helium has caused prices to increase significantly. Many GC users are considering switching to hydrogen as a carrier gas. Hydrogen provides many advantages over helium including, higher resolution, shorter run times, longer column life, and cost savings. Many instrument manufacturers now provide resources to make switching carrier gas easier. This How To Guide will take you through the steps necessary to convert from helium to hydrogen as a carrier gas for Gas Chromatography.  Click here. |

Preparative OBD Columns with Analytical Performance
Scaling an analytical method to preparative column dimensions requires chromatographically equivalent columns. Using the same column chemistries and by matching the analytical and preparative column bed densities, scalability can be assured, eliminating the need for method re-development. In scaling methods, scientists save time and improve efficiency with Waters premium column brands that are fully scalable from analytical to preparative Optimum Bed Density (OBD) columns  Learn more. |
