Nitrogen Generation for Pharmaceuticals


Most pharmaceutical companies have multiple nitrogen uses and purity demands. Lab GCs and some other low-flow processes require very low flow at very high purity (99.999%-99.9995%), while the LCMS requires only about 99%-99.9%. Labs may also need small volumes of liquid N2 for freezing. The balance of most pharmaceutical nitrogen applications are blanketing, inerting and sparging (99%-99.9%). The latter is by far the largest demand, accounting for most of the nitrogen use in the facility.

Many companies believe that since they have high purity needs in the lab, they also have to have high purity or liquid N2 throughout the facility. Not necessarily so. Our small-lab nitrogen generator systems can provide the needed high-purity nitrogen for the GC and other high-purity users. A large PSA nitrogen generator or membrane nitrogen generation system can then be used to provide lower purity needs to the rest of the facility. We can come in and do a complete assessment for your nitrogen application.
