GC can be used to identify the make-up of virtually any material. Once a sample has been prepared, it is injected into the GC along with a carrier gas, its component parts are separated in the column and identified when they reach the detector.
Carrier gas purity is imperative for several reasons: impurities in the carrier gas will react with the GC column reducing its lifespan; impurities will also cause noise in your baseline and reduce peak resolution.
As no special fittings are required, it couldn’t be easier to – simply order BIP® technology gases in place of your ordinary UHP gases.
Through the inclusion of a unique integrated purifier in each BIP® technology cylinder, we can guarantee the lowest levels of critical impurities: oxygen, moisture and total hydrocarbons which are the most damaging in gas chromatography applications.
It isn’t necessary to use inline purifiers with BIP® gases; in fact we recommend that you remove them from the line once you switch over to BIP® technology gases, as there is a high possibility that they will actually introduce impurities to the gas stream.
When considering the cost of ultra-high purity gases users don’t tend to take into consideration the hidden costs, which can quickly add up.
There are many more factors than the price of the cylinder that should be considered:
How much could you save if the life of your column was longer?
With an integrated purifier you can use more gas from a cylinder without contamination concerns
There is both a financial and time cost associated with inline purifiers
