    Abstract

    Current demanding GC and GC/MS applications have an increased focus on sensitive and reproducible qualitative and quantitative analysis of more challenging active analytes. An inert GC flow path is required to prevent the adsorption of the active compounds of interest onto active sites anywhere from injection to detection. Building on our experience developing enhanced surface deactivation chemistries [1], Agilent has successfully improved the inertness of the entire GC flow path. The fl ow path is directly in contact with critical, active analytes that are susceptible to break down or otherwise inferior chromatographic detectability. Enhancing the fl ow path deactivation has made signifi cant improvement in the sensitivity and reproducibility of measurements using Ultra Inert (UI) deactivated products. These include Agilent Ultra Inert apolar and midpolar columns [2,3,4], Agilent Ultra Inert liners [3,4], Agilent Ultra Inert Gold Seals, split/splitless top, shell weldments [5], and Agilent Ultimate Plus deactivated fused silica tubing [6]. The knowledge and experience gained developing these products led to the development of an Ultra Inert polar, “WAX column” based on 100% polyethylene glycol (PEG) stationary phase. Agilent J&W WAX type columns have been the industry standard over the last 35 years. These columns are used to analyze a wide variety of compounds with polar functional groups, saturated compounds in fl avors and fragrances, and industrial chemical quality control. In this competitive comparison, we present the Agilent DB-WAX Ultra Inert GC column.
