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 Stratum PTC builds on eight 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 Stratum PTC uses components that are absolutely essential to perform a successful Purge and Trap analysis; those being a mass flow controller (MFC), superior trapping technology, and inert sample pathway. The heart and soul of our Purge and Trap System 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 and pressures at any time during the Purge and Trap process. The Teledyne Tekmar StratTrap offers trapping benefits that have never been seen before by Purge and Trap concentrators. The StratTrap 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 StratTrap is desorbed rapidly and the VOCs are delivered to the GC system quickly. One important key to minimize carryover is the Stratum PTC’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. Note: The Stratum TekLink™ software runs in a Microsoft® Windows XP or greater environment.
