EPA TO-14A Aromatic Subset Mix [100 ppb in nitrogen, pkg of 110 L (pi-marked cylinder)] may be used as a chemical reference standard for the qualitative calibration of air monitoring and industrial hygiene equipment. These standards are available in both liquid solutions and gaseous blends, to accommodate calibration of today′s variety of air monitoring and analysis devices and applications. Each standard includes a Certificate of Analysis summarizing the testing data. Each standard solution is provided in a flame-sealed amber ampoule. Each gaseous standard is provided in a transportable cylinder for ease of use in either the laboratory or the field.
These high pressure, transportable gas calibration blends for US EPA Method TO-14 ensure that laboratories can perform Method TO-14 and Clean Air Act analyses at a fraction of their former costs. Scott TO-14 gas blends are packaged in SCOTTY HP high pressure, transportable, laboratory-size cylinders. Scott TO-14 gas calibration blends are traceable to NIST reference mixtures (NIST SRM 1804) and are certified by Scott Gases for superior stability and accuracy.
