PerkinElmer Elite-Guard, Length: 5m Inner Diameter: 0.45mm, Temperature Limits: -60 to 325°C. Using the Elite-Guard or Elite-SiltekTM Guard Column lengthens the life of the capillary column and improves the analyte focusing. The 5M length of deactivated uncoated fused silica is connected to the inlet end of the capillary column and traps nonvolatile residues, preventing them from collecting at the head of the analytical column. This length of fused silica contains no stationary phase adding only a minimal amount of time to the analysis. PerkinElmer offers both the Intermediate-polarity deactivated guard column and the Siltek deactivated guard column as it is important to match the polarity of the solvent and the polarity of the surface deactivation. Elite-Guard intermediate polarity deactivated column has an operating temperature up to 325°C. Siltek deactivation creates a highly inert surface for very active compounds such as chlorinated pesticides with a maximum temperature range up to 380°C.
