NG CASTORE XL iQ Membrane Nitrogen generator with integrated direct drive Scroll compressor with Intelligent Quiet Technology.


NG CASTORE XL iQ : Membrane N2 generator High Flow for LCMS / Evaporation


Available in the Following Configurations:

  • NG CASTORE XL iQ 20 - Nitrogen generator 20L/min
  • NG CASTORE XL iQ 40 - Nitrogen generator 40L/min  
  • NG CASTORE XL iQ 70 - Nitrogen generator 70L/min 

The NitroGen series NG CASTORE XL iQ use Membrane technology.

They are engineered to transform standard compressed air into a safe, regulated supply of Nitrogen up to 70 L/min with a purity up to 99.9%.

This NG series is equipped with a scroll built-in oil less compressor with inverter technology. The new iQ series is equipped with the innovative direct drive motor-compressor system that result in lower noise than the previous version.

The exclusive electronic flow control combined with the compressor control by the inverter allows to generate Nitrogen with a higher purity using a smaller volume at less pressure of air which results in reduced energy costs and increase the life time of the compressor. Continuous control of the operating parameters of Nitrogen allows to maintain the system at its maximum efficiency.

The CASTORE XL iQ has been developed to meet specific requirements in term of gas, flow, purity and pressure in LC-MS applications. It can be used for the evaporation of solvents in samples being analysed.
