Restek Airgas Standard, Ozone Precursor/PAMS Mix, 57 Components at EPA Concentrations, 20-60 ppbC (Parts Per Billion Expressed as Carbon) in N2, 124

Each of these gas standards comes with a certificate of analysis and unique serial number. All cylinders are disposable and do not require rental or demurrage fees. Recertification of cylinders is available directly with our suppliers. All cylinders are drop-shipped from our suppliers to provide fast delivery and the "freshest" standard possible. We ensure a minimum 12-month stability on all cylinders.
