Thermo Scientific Trace 1300 – Gas Chromatography
One of the main techniques we use to characterize reaction products is Gas Chromatography (GC). Our Thermo Scientific Trace 1300 holds two columns simultaneously. The first is a standard polar column attached to a standard split/splitless injection port and a flame ionization detector (FID). We use this column to separate and quantify the organic products of our oxidation reactions. Our second column contains molecular sieves, and is attached to a gas sampling valve and thermal conductivity detector (TCD). This column is capable of separating and quantifying fixed gases (H2, O2, N2, etc.) and is attached to a gas flow regulator. By determining the concentration of each gas in our samples and multiplying by the flow rate, we can determine the number of moles of gas we produce per unit time, which is critical when studying the kinetics of reactions with gaseous products.
