Summa-type AeroSphere canisters from LabCommerce are used for convenient and reliable collection of ambient, whole air samples. These high purity, passivated, stainless steel canisters are designed to maintain the integrity and stability of the sample while it is being transported to a laboratory and stored for future analysis. Common uses include the sampling of volatile organic compounds (VOCs) in air according to EPA Methods TO-14A and TO-15.
LabCommerce calls its 6-liter air sampling canister (which the market loosely refers to as summa canisters) the Aerosphere™. It is used to collect a whole air sample for analysis by gas chromatography / mass spectrometery (GS)/MS) in compliance with US EPA Compendium methods TO-14 and TO-15. These sampling canisters are essentially electropolished stainless steel vessels. The electropolishing (summa polishing) passivates the stainless steel by creating a chromium oxide-rich surface layer on the interior of the canister.

Contrary to popular opinion, summa canisters or summa polishing is not a registered trade name, and summa polishing was just one company's name for its electropolishing processes.

Summa-type AeroSphere canisters are the highest quality air sampling canisters available. They provide excellent stability of stored compounds over time, enabling consistency in your data. Go beyond summa canister or summa polishing with LabCommerce AeroSphere's proprietary passivation.
