Linde North America, Inc. Volatile Organic Compounds (VOC) Method TO-14A

Linde’s TO-14A calibration gas standards are manufactured using exacting gravimetric techniques with all gravimetric measurements directly traceable to NIST (National Institute of Standards and Technology). Furthermore Spectra’s 39 component mix is directly traceable analytically to NIST. Linde’s base TO-14A calibration standard consists of 39 components at concentrations of either one ppm or 100 ppb in a balance of VOC free nitrogen gas with other concentrations available as custom mixtures. All TO-14A standards have one year stability. In addition, Linde supplies 41 and 43 component TO-14A gas standards.
