Specialty gases typically refer to calibration gases, zero gases, carrier gases, span gases, instrumentation gases and bump test gases. They may be either pure gases or gas mixtures containing components at concentrations extending from the per cent range down to part per billion and sometimes even part per trillion.
Specialty gases are used in analytical methods such as gas and liquid chromatography as well as Fourier transform infrared (FTIR) and non-dispersive infrared (NDIR). Other analytical methods are described in the various subpages.
Proper specialty equipment, including dedicated pressure regulators and distribution systems, should always be used with specialty gases to ensure the quality grade of the gas is not compromised through contact with sub-standard components. Generally speaking, the higher the quality grade of the gas, the higher the equipment quality should be.
When precision counts
As an established gas company and trusted supplier of specialty gases operations in many countries, we are proud of our competence and production capabilities here at Linde. We understand that purity and accuracy are essential in the world of specialty gases and always aim to match or even surpass our customers’ expectations in this area.
The knowledge and experience we have gained across an extensive range of applications give us a clear picture of the most widely used pure gases and gas mixtures. Our standard and customised products are ideal for applications such as direct read analysers, gas chromatographs, high-performance liquid chromatography (HPLC), threshold monitors, etc.
