Application Types: LC-MS, Sample Preparation, CAD & ELSD

Part number: 3300573 – XE 5020
3300190 – XE 5021

Integrated compressor: No


Producing between 20-260 L/min of high quality, laboratory grade nitrogen gas, the Infinity XE 502X can comfortably supply gas for multiple laboratory instruments. With variable nitrogen purity available between 95-99.5% (depending on flow rate), Infinity XE generators can be configured to suit the needs of several applications, such as LC-MS, ELSD, Sample Preparation & more.

Peak Scientific’s Infinity XE series generators have been engineered to provide nitrogen gas to laboratories that already have an external source of clean, dry & oil-free air; and meets a minimum grade of ISO8573-1:2010 Class 1.4.1 – NB: Were this is not available, Peak can provide consultative assistance on what specifications of compressed air & pre-filtration are required, as well as supply these items as part of a complete Infinity XE gas generation solution.

Infinity XE series nitrogen generators are effectively silent whilst in operation and have no moving parts, so require minimal annual maintenance.

Models available with or without optional O2 analyzer & purity safeguard system.
