ENVIRONMENTAL & VOC STANDARDS

The HiQ® specialty gases program from Linde supplies high purity gases, gas mixtures, precision engineered equipment and gas distribution systems, and services and support, to a wide range of industries employing specialty gases applications. In addition to the line of SPECTRA high purity gases the HiQ® program includes the REDLINE® and BASELINE® trademarked equipment product ranges and the SPECTRA-SEAL®, ECOCYL® and VERISEQ® specialty gas ranges.

HiQ® products represent Linde’s commitment to the highest available quality and global consistency across gases, equipment and services.

All Standard VOC is available as following specification and sizes:

  • The United States Environmental Protection Agency's ozone precursor monitoring program known as PAMS, Photochemical Assessment Monitoring System, utilizes Linde standards for program quality assurance.

    Linde offers the PAMS standard at the EPA specified concentrations expressed as ppb C (parts per billion expressed as carbon) and also at 100 ppb v/v and 1 ppm v/v. The PAMS calibration standard is supplied in a size 2A cylinder or a size 6A cylinder with guaranteed stability of 12 months.
