Main advantages of the LUMIN PTC

  • Electronic Mass Flow Controller allows for use with either Helium or Nitrogen. The ability to vary flow rates in different modes increases sample throughput
  • Ultra-low carryover
  • New Moisture Control System (MCS) reduces moisture by up to 60% over previous models
  • Proprietary trapping material allows for excellent desorption efficiency
  • Automated leak checking
  • Sample logging ensures data integrity
  • Foam detection and prevention options
  • Software control allows for built-in diagnostics and self-testing

In 1974, Tekmar developed an idea that revolutionized the way laboratories performed Volatile Organic Compound (VOC) testing. Since then, Tekmar has continued to build on the foundation of the initial Purge and Trap technique one innovative layer at a time. The Lumin builds on seven previous generations, making us the industry’s cornerstone of technique and support.

The fundamentals of Purge and Trap are time proven. By bubbling a purge gas through your sample matrix, the VOCs are removed and collected on an analytical trap. After the purging is complete, the trap is heated and the VOCs are released and delivered to a gas chromatograph for separation and detection. The Lumin uses components that are absolutely essential to perform a successful Purge and Trap analysis; those being an electronic mass flow controller (MFC), superior trapping technology, and inert sample pathway.

The heart and soul of all of Tekmar Purge and Trap systems is the Teledyne Hastings Mass Flow Controller. The MFC delivers the purge gas with unmatched precision and accuracy. The most advantageous feature of utilizing the MFC is the ability to instantaneously change the gas flows via the Teklink software, at any time during the Purge and Trap process.

The Teledyne Tekmar U-shaped trap offers trapping benefits that have never been seen before by Purge and Trap concentrators. The U-shaped trap is capable of adsorbing the VOCs of interest while minimizing the collection of unwanted compounds, such as water. The ultra-fast trap heater ensures that the U-shaped trap is desorbed rapidly and the VOCs are delivered to the GC system quickly. Just as importantly, the Lumin cools the trap faster than ever, thanks to an improved fan, and dedicated ductwork. These features allow precise control of the trap cooling air, reducing total run time and increasing sample throughput.

The key to minimizing carryover is the Lumin’s inert sample pathway. The tubing and fittings have been treated to provide unprecedented low carryover which permits the enduser to calibrate with more confidence.
