Direct Sample Probe: Flexibility beyond expectation
The Direct Sample Probe system for the DSQ and PolarisQ GC/MS is ideal for qualitative or semi-quantitative analysis of materials that are difficult, or impossible to elute chromatographically. For rapid and reliable analysis, the direct sample probe is an alternative that reduces or eliminates sample preparation. Moreover, this technique requires a minimal sample amount for testing.
Direct Probe Features:
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.
• Direct Exposure Probe (DEP)
Rapid heating filament for liquids or
solutions. The DEP is ideal for rapid
molecular weight confirmation of solids
dissolved in a suitable solvent.
• Direct Insertion Probe (DIP)
Slower volatilization with heated capillary
tube for solid samples. The DIP can be
utilized for rapid analysis of solids or
trace components in solid matrices, like
forensic samples, tissue,ect.
• Analysis of highly polar, thermally labile
solid or liquid compounds
• Compatible with all modes of ionization
and mass analysis
• Switch to probe in under three minutes
with GC interface undisturbed

Liquid CI
Use Water, Methanol, Iso-propanol as reagent gas.
By choosing the right reactant gas selective reactions with certain compound classes can be tuned and optimized.
• Comparable sensitivity
• Less background in PCI
• Good tuning , stable spectra
• Stable over several hundred analyses
• Works both in PCI and NCI
