Peak Scientific has introduced a new addition to its Solaris Nitrogen range, the new Solaris XE. Solaris XE can deliver up to 35 L min–1, at purity levels of up to 99.5% making it suitable for LC-MS applications. The Solaris XE has variable purity in relation to outlet flow and pressure, and so is also capable of supplying compact MS instruments or multiple evaporative light scattering detector instruments simultaneously. The Solaris XE has been specifically designed to provide nitrogen to laboratories that utilise an external source of compressed air and its compact chassis allows it to be placed on a benchtop or on a wall.
