    Calibration Gas Mixtures - Consistency You Can Trust for 5 Years

    Calibration standards of low-level reactive mixtures, typically those below 5 ppm, can prove to be unstable over time. This can result in incorrect measurements, lost productivity and, with emission monitoring, potential legislative fines introduced in 1973.

    Proprietary process to render the aluminium surface of the cylinder chemically inert. Convert this passivation layer into a smooth,tightly adherent surface, with negligible adsorptive properties. As a result guarantee that SPECTRA-SEAL calibration gas mixtures will remain stable, with a consistent analytical response for 5 years from their manufacturing date.

    BOC (UK) can provide spectra-seal treatment on a wide range of calibration gases for the environmental monitoring industry including: 20ppm Carbon Monoxide (CO) balance Nitrogen (N2), 450ppb Nitric Oxide (NO) balance Nitrogen (N2), 450ppb Nitrogen Dioxide (NO2) balance Air, 450ppb Sulphur Dioxide (SO2) balance Air.
