This application note shows the possibilities and limitations in fast analysis of saturated and unsaturated C1 to C3 hydrocarbons using an Agilent 490 Micro GC. The chromatograms and results outline the similarities and differences when using a PoraPLOT U and a PoraPLOT Q column channels.
This document describes the possibilities and limitations in fast analysis of saturated and unsaturated C1 to C3 hydrocarbons using an Agilent 490 Micro GC. It outlines the separation characteristics when using a PoraPLOT U column channel versus a PoraPLOT Q column channel, noting that both are capable of resolving methane from the composite air peak and separating CO from methane and C2 hydrocarbons.
The PoraPLOT U column channel provides baseline separation for ethane, ethylene, and acetylene.
When using the PoraPLOT O column channel, ethylene and acetylene coelute.
The column temperature used in the described setup is 80°C.
