The Dani Master Purge & Trap (DHS/P&T) system is a versatile and sensitive solution for VOC analysis across multiple industries, providing excellent detection capabilities and integration with GC/GC-MS systems.
Key Features:
- Dynamic Headspace Sampling: Sweeps volatiles from the sample headspace using a precise flow of inert gas.
- Dual-Needle System: Focuses volatiles into an adsorbent-packed trap.
- Thermal Desorption: Rapidly desorbs analytes for introduction into the gas chromatographic column.
- Automated Operation: Fully automated system for high throughput and minimal manual intervention.
- Versatility: Suitable for both liquid and solid samples.
Technical Specifications:
Trap Characteristics
- Trap Material: Typically Tenax, carbon molecular sieve, or other VOC-adsorbing resins.
- Trap Dimensions: 1/8” diameter, approximately 20 cm length, packed with multiple adsorbent layers.
- Trap Temperature:
- Cooling: Down to -30°C (or ambient if no cryogenic cooling is used).
- Heating: Up to 350°C for rapid desorption of VOCs.
- Heating Rate: Up to 1000°C/min.
Purge Parameters
- Purge Gas: Helium or Nitrogen (99.999% purity recommended).
- Purge Gas Flow Rate: Adjustable from 5 mL/min to 500 mL/min.
- Purge Time: Configurable between 1 to 20 minutes depending on the sample and required sensitivity.
- Sample Volume: Up to 500 mL for water, or smaller for solid samples.
Desorption System
- Desorption Time: 1-2 minutes for complete VOC transfer to the GC column.
- Desorption Temperature: Up to 350°C.
- Trap Backflush: Ensures effective cleaning of the trap between analyses and prevents carryover.
Transfer Line
- Heated Transfer Line: Maintained between 100°C to 200°C to avoid condensation of VOCs.
- Length: Approximately 1 meter, designed to connect seamlessly with GC or GC-MS systems.
- Inert Coating: The internal surface is deactivated to prevent adsorption or interaction with analytes.
Physical and Environmental Specifications
- Power Supply: 110V or 220V, 50/60 Hz, 400-600W.
- Operating Temperature: 10°C to 40°C.
- Environmental Conditions: Humidity range 20% to 80%, non-condensing.
- Dimensions: 400 x 500 x 500 mm
- Weight: 25 kg.
Key Advantages:
• Unmatched Sensitivity: High sensitivity with no sample manipulation
• High Productivity: Increased analytical performance.
• Reliability: Consistent and reliable results with minimal maintenance.
• Ease of Use: User-friendly interface and automated operation.
• No Cross-Contamination: Ensures clean and accurate results.
