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 our 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 user to calibrate with more confidence.
