The Direct Sample Probe system for the Finnigan TRACE DSQTM, Finnigan FOCUS DSQ, and Finnigan PolarisQ is ideal for the quick screening of samples or for any application which doesn't require a GC column separation. A single controller box with interchangeable probe tools makes it easy to select the best method of sample introduction. The system includes either a Direct Exposure Probe (DEP) with a heated filament for liquids or solutions or a Direct Insertion Probe (DIP) with heated capillary tube for solid samples. The DEP is ideal for rapid molecular weight confirmation of solids dissolved in a suitable solvent. The DIP can be utilized for rapid analysis of solids or trace components in solid matrices such as forensic samples, tissue, etc.
