Chrysalis II LC/MS Nitrogen Generator

The Chrysalis® II LC/MS M-4 Nitrogen Generator is specifically designed to deliver the larger capacity flow rates required for LC/MS instrument operation. The Chrysalis® II LC/MS M-4 utilizes an integral membrane based system to transform standard compressed air into a continuous stream of high purity dry nitrogen. The LC/MS M-4 can produce flow rates from 1 Lpm up to 30 Lpm, with purities ranging from 96 to 99.9%. An optional PUR-GasTM UHP purification system is available to increase outlet nitrogen purity to 99.9999%, for flow rates up to 20 Lpm.

 

The Chrysalis® II LC/MS M-4 Nitrogen Generator incorporates an integral oil-free direct drive air compressor system to continuously supply the air to the gas generator inlet. Caster wheels for floor mobility are standard.

 

The design of the Chrysalis II® LC/MS M-4 Nitrogen Generator is based on hollow fiber membrane technology. Pressurized air is directed through a series of hollow fiber membrane tubes where, due to their high diffusion rates, oxygen, water vapor and carbon dioxide molecules diffuse rapidly out of the stream through the membrane walls. Nitrogen, which has a low diffusion rate through the membrane, is predominantly retained inside the membrane flow stream.

 

The first membrane stage eliminates most of the moisture and oxygen from the air stream. The pre-purified nitrogen then passes through a second membrane stage where more moisture, water vapor and carbon dioxide are removed. In the delivery stage, the nitrogen stream passes through a third membrane for final purification.

 

The nitrogen pressure out of the third membrane stage is then elevated from 45 psig to a standard discharge pressure of 115 psig. Operating the membranes at a lower initial pressure and then boosting the pressure downstream results in extending membrane life compared to traditional designs that utilize a single compressor to operate throughout the entire pressure range. This also serves to extend the operating life of the air compressor components and significantly reduces routine maintenance requirements and costs. The LC/MS Nitrogen Generator is also available without an integral air-compressor (the M-0 model) and operates from an external compressed air source. The Chrysalis® II LC/MS M-0 is capable of

producing flow rates up to 60 Lpm. The LC/MS M-0 model is compact, lightweight, economical and is wall mountable.
