US EPA Compendium of Air Methods TO-14A And TO-15 regulate the collection, storage, ａnd analysis of volatile organic compounds （VOCs） using treated air sampling canisters. Restek offers a complete line of TO-Can? canisters （SUMMA can equivalent）, electropolished using a proprietary process ａnd extensively cleaned using an ultrasonic method. This ensures a high-quality, passivated surface that maintains the stability of TO-14A/TO-15 compounds during storage. The frame surrounds the electropolished canister, eliminating the need for weld marks on the sphere, thereby preventing active sites on the canister. The Parker Hannifin metal-to-metal diaphragm valve supports the excellent performance of the canister.
The unique holder attaches the handle ａnd base to the canister without welds, ａnd protects the canister, tube stub, ａnd valve. The 2/3-turn diaphragm valve has a metal-to-metal seat ａnd a temperature limit of 250°C. We leak check the system with helium to ensure the TO-Can? canister ａnd valve are leak-tight, then pressurize the canister with contaminant-free nitrogen before we ship it.

US EPA空气监测规定的TO014，TO-15要求使用经过处理的空气采样罐来采集和储存VOC气体。我们的TO-Can罐是使用专有电抛光技术和超声工艺进行处理，满足这个要求。SUMMA采样罐也满足这个要求。这了质量，罐的内表面需要进行钝化处理，使TO-14/TO-15的成份在储存中保持稳定。电抛光罐体球形外框架不用焊接，防止活性点出现。采用了Park Hannifin的金属对金属薄膜阀了采样罐具有优良的性能。上面的把手也不是焊接的，它起到支撑管道和阀的作用。2/3转向阀也是金属密封，很容易判断是对于“开”还是“关”的状态。阀可耐温250摄氏度。出厂时先采用氦检漏仪对罐和阀进行检漏，然后充装高纯氮气保存。

• SUMMA canister equivalent.等同于苏玛罐。
  
• Excellent analyte recovery－－even after 14 days of storage.极好的采样分析装置-可保持14天不变质。

Restek canisters are originally equipped with high-quality Parker Hannifin diaphragm valves. Each valve is helium leak-tested to 4 x 10^-9cc/sec. The all-stainless steel construction eliminates contamination ａnd withstands temperatures from -100°C to 250°C. Other features include a compression outlet fitting ａnd a 1/4" inlet ａnd outlet.
*If attaching any of Restek＇s passive sampling kits to a 3L canister, use a Siltek treated （cat.# 563646） or stainless steel （cat.# 563647） connector between the two components.
