Ultra-High-Purity Acetylene C₂H₂ UHPSupplier & Manufacturer in India

UHP acetylene with ultra-low PH₃ & H₂S for labs and AAS.

Formula: C₂H₂ (UHP)Impurities: Ultra-low PH₃ & H₂SState: Dissolved in acetone
C₂H₂ UHP

Ultra-high-purity acetylene with ultra-low phosphine and hydrogen-sulphide impurities for precision flame work and atomic-absorption spectroscopy.

Ultra-high-purity (UHP) acetylene is dissolved acetylene refined to ultra-low PH₃ and H₂S levels, demanded where flame stability and freedom from contaminants are critical. It is the standard fuel gas for atomic-absorption spectroscopy (AAS) and is used for precision flame cutting and welding in laboratories, aerospace, automotive and pharmaceutical work.

As a manufacturer of acetylene since 1947, IIGAS produces UHP acetylene with tight quality control and full traceability.

Frequently asked questions

UHP acetylene is refined to ultra-low phosphine (PH₃) and hydrogen-sulphide (H₂S) impurities, giving the clean, stable flame required for spectroscopy and precision work.
It is the standard fuel gas for atomic-absorption spectroscopy (AAS), where contaminant-free, stable flames are essential for accurate measurement.
As dissolved acetylene in acetone-charged porous-mass cylinders, refined to ultra-high purity.
Laboratories, aerospace, automotive and pharmaceutical sectors for precision flame work and analysis.
Both are dissolved acetylene, but UHP grade has tightly controlled, ultra-low impurities for analytical reliability.
As with all DA, withdraw no more than about one-seventh of the cylinder contents per hour to avoid acetone carry-over.
The same as dissolved acetylene — flashback arrestors, upright storage, no use above 1 bar at the torch, and separation from oxidisers.
Yes — UHP acetylene is supplied with purity documentation and traceability.
Yes — as global leaders in acetylene since 1947 we control purification and filling in-house.
