Helium ECD from Linde is an ultra-high purity inert gas with a purity of ≥ 99.999%, specifically designed for analytical applications in gas chromatography with electron capture detection (GC-ECD).
Its extremely low impurity levels make it ideal for trace analysis, where baseline stability and minimal noise are critical. It serves as a carrier and operational gas in GC-ECD systems, commonly used for detecting halogenated compounds, pesticides, and persistent organic pollutants.
In addition to analytical use, helium ECD is also suitable for industrial applications such as purging in metallurgy, reactor cooling, glass fiber production, leak testing, and laser gas mixtures.
