Modern GC and GC/MS instruments are important analytical tools for accurate and reproducible measurement of many compounds at low ppb level in a wide variety of matrixes . For accurate analyte measurement, compounds need to survive the journey through the flow path. The flow path can contain different metal components, which need to be deactivated when compounds are more (re)active than alkanes, for example pesticides, alcohols, or very polar compounds. In this technical overview, Agilent UltiMetal Plus deactivated stainless steel tubing and stainless steel connectors and fittings were tested and compared to bare stainless steel and products that were deactivated by different methods. Because analysts have to investigate reactive components at ever lower detection limits, UltiMetal deactivation chemistry, developed in the 1980s, is now improved and known as UltiMetal Plus. UltiMetal Plus technology is applied specifically to steel and stainless steel surfaces, and can be used safely when stainless steel products are defined or prescribed in a method. UltiMetal Plus technology provides a significant improvement. Agilent and non-Agilent products are compared in this study.
