Air quality of compressed air FOR NITROGEN generators for LCMS, and zero air :
ISO 8573.1 CLASS 1.2.1
The new international standard for compressed air quality introduces a simple classification system for the 3 main contaminants present in any compressed air system : dirt, water and oil.
If the LCMS nitrogen generator is connected to a non-lubrificated compressor, the fridge dryer is efficient.
If the compressor is lubrified, it is recommended to use an adsorption dryer.
