Dani Master Purge & Trap (Refurbished)

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.
