Stratum
The Stratum PTC builds on eight previous generations, making us the industry’s cornerstone of technique and support. 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.
Including the The StratTrap system, 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.
