U.S. EPA Methods TO-14A and TO-15A 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/TO-15A compounds during storage. A frame surrounds the electropolished canister, eliminating the need for weld marks on the sphere, thereby preventing active sites on the canister. The high-performance valve supports the excellent quality of the canister.
A unique holder attaches the handle and base to the canister without welds and protects the canister, tube stub, and valve. The valve is an exceptionally high-quality, metal-to-metal seal, 2/3-turn valve with metal diaphragms to prevent sample adsorption for more accurate results. Each canister is slightly pressurized with contaminant-free nitrogen prior to shipment.
