Parker Hannifin offers gas generators that utilize membrane, PSA and catalyst technologies to generate research grade gases. Parker’s Balston and domnick hunter gas generators offer technical and economic benefits over cylinder gases. Nitrogen generators are designed to continually transform standard compressed air into commercially sterile nitrogen at safe, regulated pressures without operator attention. Hydrogen generators eliminate hazardous hydrogen storage. Zero Air generators are ideal for FID applications and allow instrument users to replace costly helium cylinders.
