Liquid Chromatography (LC; LC-MS)

For more than 30 years, LNI Swissgas has developed premium laboratory Nitrogen Gas Generators used in laboratories worldwide and designed for a wide range of analytical applications. Our solutions support Liquid Chromatography (LC) and, in particular Liquid Chromatography–Mass Spectrometry (LC-MS), as well as gas chromatography and sample evaporation systems across both laboratory and industrial environments.

LNI offers a complete range of Nitrogen (N₂) and Nitrogen + Air generators, available with or without integrated compressors to meet every laboratory configuration.

Our smart nitrogen systems deliver up to 99.9999% pure N₂ with flow rates ranging from 500 cc/min to 120 L/min, providing a cost-effective, reliable, and environmentally sustainable alternative to traditional gas cylinders.

All generators are engineered to fulfil the precise flow, purity, pressure and air-quality requirements of modern LC and LC-MS instruments.

LNI Swissgas also develops OEM-dedicated configurations tailored for the world’s leading analytical instrument manufacturers, including Agilent, Shimadzu, Sciex, Thermo Fisher Scientific, Waters and many more – ensuring validated compatibility and optimal system performance.
