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空氣監(jiān)測規(guī)定的TO014,TO-15要求使用經過處理的空氣采樣罐來采集和儲存VOC氣體。我們的TO-Can罐是使用專有電拋光技術和超聲工藝進行處理,滿足這個要求。SUMMA采樣罐也滿足這個要求。這了保證質量,罐的內表面需要進行鈍化處理,使TO-14/TO-15的成份在儲存中保持穩(wěn)定。電拋光罐體球形外框架不用焊接,防止活性點出現(xiàn)。采用了Park Hannifin的金屬對金屬薄膜閥保證了采樣罐具有優(yōu)良的性能。上面的把手也不是焊接的,它起到支撐管道和閥的作用。2/3轉向閥也是金屬密封,很容易判斷是對于“開”還是“關”的狀態(tài)。閥zui高可耐溫250攝氏度。出廠時先采用氦檢漏儀對罐和閥進行檢漏,然后充裝高純氮氣保存。
- SUMMA canister equivalent.等同于蘇瑪罐。
- Excellent analyte recovery--even after 14 days of storage.的采樣分析裝置-可保持14天不變質。
Instruction Sheets:
*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.
