Koehler - Gas Chromatography System for Free and Total Glycerin

This simple-to-use biodiesel GC system is ideal for the quantitative determination of free and total glycerin in B100 methyl esters by gas chromatography. The calibrated results are displayed directly, eliminating off-line calculations.

Both the carrier gas and the Flame Ionization Detector (FID) combustion gas are controlled by programmable Electronic Pressure Controllers (EPCs). EPCs not only provide rock-solid retention time reproducibility, but allow the carrier gas to be pressure ramped (just as the column oven is temperature ramped) from the built-in PeakSimple data system.

The on-column injector is ideal for 1⁄8" packed and 0.53-mm wide-bore capillary columns, and is suitable for analyses ranging from methane to heavy, high-boiling hydrocarbons (C44+). The column oven accepts column cage diameters up to four inches, is programmable to 752°F (400°C), and recycles quickly with its high-speed cool-down fans.
