* Electronic Mass Flow Controller allows for use with either He or N2. Patent pending ability to vary flow rates in different modes which increase sample throughput
* Ultra-low carryover
* Superior water management
* 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
The Stratum Purge and Trap Concentrator utilizes an electronic Mass Flow Controller that delivers
extraction gas to the sample, thus stripping the VOCs and delivering them to a sorbent trap. The trap is then heated and back-flushed to a GC for separation and subsequent detection. The system then automatically performs a clean-up step, allowing for the next sample analysis.

吹扫捕集原理是经过了时间验证的可靠技术。让吹扫气体以密集和细小的泡状形式通过待分析的样品基体，VOCs被吹扫气带出样品并吸附收集于捕集阱中；吹扫过程完成后，加热捕集阱，VOCs由捕集阱中解析并被传输至气相色谱仪（GC），气相色谱仪将输入的VOCs中的不同成分分离并检测。Stratum PTC的组成部分都是完成成功的吹扫捕集分析所必不可少的，包括：质量流量控制器（MFC），高级的捕集技术及惰性的样品传输管路。
Tekmar吹扫捕集系统精华与灵魂所在是Teledyne Hasting质量流量控制器（MFC）。它以无比的精确性和准确度传输着吹扫气体。而使用它的最大的优势和特点是我们能在吹扫和捕集过程中的任何时间即时地调整气流和气压。
Teledyne Tekmar StratTrap捕集阱提供了前所未见的捕集性能。它能高效地吸附我们所需的VOCs，而且同时能够使其他不必要的化合物的吸收达到最小化，比如水份。此外，超高速的捕集阱加热器保证了我们的StratTrap捕集阱能快速地解析，而VOCs也更快地被传输到GC，大大地提高了分析效率。
保证残余物（carryover）最小化的关键是我们Stratum PTC的惰性样品传输管路。仪器中所有的管路和接头都经过了特殊的钝化处理，空前的改善了残留现象。用户可以更为放心的使用仪器。
Note: The Stratum TekLink™ software runs in a Microsoft® Windows XP or greater environment.
