In industries such as oil & gas, environmental monitoring, food processing, healthcare, and electronics manufacturing, ensuring the accuracy of measurement equipment is a critical requirement. To achieve this, Calibration Gases are an indispensable solution.
VI NA Industrial Gases is an authorized distributor of Air Products in Vietnam. We offer a wide range of calibration and specialty gas mixtures tailored to customer specifications—serving applications from instrument calibration to specialized production processes.
Depending on the intended use, our gas products are classified into two main categories:
CALIBRATION GASES
Calibration gases are precisely blended gas mixtures used for calibrating measurement devices, environmental monitoring systems, toxic and flammable gas detectors, and laboratory analysis instruments.
| Application Area | Typical Calibration Gases | Catalog |
| Oil and gas, oil and natural gas refining
|
– C1–C6 Hydrocarbon Mixtures: Methane, Ethane, Propane, Butane, Pentane, etc.- for natural gas composition analysis
– BTX Mixtures: Benzene, Toluene, Xylene – for aromatic compound analysis in gasoline and fuel – LPG Calibration Gas: contains Propane, Butane, Pentane, etc. – for calibrating LPG analyzers – HRVOC Mixtures: for analyzing Highly Reactive Volatile Organic Compounds |

| Calibration of gas detector: | – Toxic & flammable gases: NO, NO₂, SO₂, CO, CO₂, CH₄, H₂S… – for calibrating gas detectors and explosion-proof safety monitoring systems | Download data here |
| Environmental control – emissions:
|
– CEMS Calibration Gases: NOx, SO₂, CO, CO₂, CH₄, H₂S in balance N₂/Air – for calibrating Continuous Emission Monitoring Systems
– EPA-standard gas mixtures: for internationally standardized measurement methods |

The range of gas mixtures we offer is highly diverse — from simple two-component mixtures to complex multi-component blends with low ppm concentrations. These mixtures are suitable for both LEL (Lower Explosive Limit) calibrations — the minimum concentration of a flammable gas in air capable of ignition — and high-precision laboratory standards.
In addition to a wide selection of standard gas mixtures, Air Products also provides custom-blended mixtures tailored to specific customer requirements.
PROCESS GAS MIXTURES
These are gas mixtures specially blended to meet the specific requirements of industrial production processes. They are designed to offer high stability and compatibility with equipment used in continuous operations.
| Application Area | Gas Mixtures | Catalog |
| Welding and cutting metal: | Ar + CO₂, Ar + O₂, He + Ar – used in MIG/TIG welding, arc shielding gases, laser cutting, plasma cutting | Download data here |
| MAP food packaging: | CO₂ + N₂, O₂ + CO₂ (MAP) – for preservation, extended shelf life, and maintaining color and flavor in food | Download data here |
| Diving gas: | He + N₂ + O₂; O₂ + He; N₂ + O₂ – supply oxygen and stabilize pressure based on diving depth | Download data here |
| Semiconductor technology: | H₂ + N₂, NH₃ + H₂, O₂ + Ar – for cleaning, plasma etching, and creating controlled gas environments | Download documents here |
