Direct Sample Probe GC/MS 附件
The Direct Sample Probe system for the DSQTM, FOCUS DSQ, and PolarisQ is ideal for qualitative or semi-quantitative analysis of materials that are difficult, if not impossible to elute chromatographically.
The Direct Sample Probe system 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.
• 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, such as forensic samples, tissue,
- Quick, simple method for sample introduction directly in mass spectrometer source
- Switch to probe in under three minutes with GC interface undisturbed
- Powerful screening technique
- Analysis of highly polar, thermally labile, or solid compounds
- Compatible with all modes of ionization and mass analysis
- Available in two styles: rapid heating filament Direct Exposure Probe （DEP） and slower volatilization Direct Insertion Probe （DIP）
