Gas Chromatography Helium is generally preferred as carrier gas over nitrogen and hydrogen because all of above it is inert it has a lower viscosity it doubles up as a party gas for balloons and funny voices all of above it is inert it has a lower viscosity it doubles up as a party gas for balloons and funny voices ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Split injection is carried out by splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject sequentially splitting the sample into smaller portions to inject at the same time through parallel ports None of these splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject sequentially splitting the sample into smaller portions to inject at the same time through parallel ports None of these ANSWER DOWNLOAD EXAMIANS APP
