Peak scientific has a full range of air solutions including zero air generators, ultra zero air generators, and calibration gas (CO2 free air) generators for use with applications such as GC, TOC and CO2 analysis. They can also provide Precision air compressors for use with our Precision nitrogen and zero air gas generators.Zero Air Generators remove hydrocarbons via a process of oxidative catalysis to ensure it only contains less than 0.1 parts per million (PPM) of total hydrocarbons.
