Analyze Semivolatiles with Agilent J&W Ultimate Plus Tubing in an Inert Flow Path

Version 1

    Application Note




    A fast and reliable analysis of semivolatile contaminants in environmental samples at trace levels remains a great challenge due to the broad variety of compounds and matrix complexity. Highly sensitive analytes often show poor peak shape, poor reproducibility, and significant loss of sensitivity because of their adsorption or degradation onto active sites anywhere in the instrument flow path. The reproducible and sensitive analysis of these compounds, therefore, requires an inert flow path from injector to detector. Agilent J&W Ultimate Plus deactivated fused silica tubing has great potential in contributing to an inert flow path. This application note provides a detailed evaluation of Ultimate Plus deactivated fused silica tubing versus tubing promoted as having superior performance from another supplier, as GC restrictors for MS in the analysis of a semivolatile checkout mixture. Good peak shapes and significant response improvements for most analytes, especially challenging compounds susceptible to active sites on the surface of deactivated fused silica tubing, provide evidence of better inertness performance from the Agilent tubing
