Abstract Information :

Today's demanding GC and GC/MS applications mainly focus on sensitive and reproducible qualitative and quantitative analysis of more challenging analytes. WAX GC columns, based on 100% Polyethylene Glycol (PEG) stationary phase, are commonly used for analysis of a wide variety of compounds with polar functional groups. They are an ideal choice for numerous applications in quality control and method development labs. Applications in these industries often involve complex mixtures of polar compounds containing a variety of polar functional groups.

Traditional WAX GC columns have had some shortcomings. In comparison to polysiloxane stationary phases the maximum operating temperature of a WAX GC column is much lower, mainly up to 250°C/260°C. A new innovative WAX column is developed, with improved thermal stability, giving better column-to-column reproducibility over the life of the column. With its maximum temperature limits of 280°C isothermal and 290°C programmed for standard 30m x 0.25mm x 0.25µm configuration, this provides several advantages.
