SimDis Inlet®
Gas chromatography, like all instrumental techniques, cannot be used successfully if potential sources
of error are not understood and steps taken to avoid them. In the case of simulated distillation, making
sure the samples are completely and consistently introduced to the GC column is absolutely critical.
If not, the boiling point distribution information produced will not be correct. This is especially true
if the boiling range of the sample is C5 to C40 or higher.
The culprit is boiling point discrimination. That is, sample components with higher boiling points vaporize more slowly than those with lower causing them to enter the GC column in a non-uniform/non-representative manner. Such is the case for inlet systems that are isothermal. (ex. packed, purged packed and split/splitless).
To overcome the problem, we developed and patented a novel temperature programmable SimDis Inlet® that vaporizes the sample and introduces it to the column in a consistent manner producing highly accurate results. Results you can depend on.
