CETAC U-6000AT+ Nebulizer
and
AridusTM Desolvating Microconcentric Nebulizer

The Aridus sample introduction system is a third generation sampling device that provides the advantages of desolvation and micro-volume sampling. The U-6000AT+ adds a second desolvation stage (membrane desolvator) to the U-5000AT+ nebulizer. The membrane desolvator effectively removes solvent (water and volatile organics) which escapes from the U-5000AT+condensor. The use of these two systems provides up to two order of magnitude enhancement in sensitivity, improves detection limits and reduces many polyatomic ion interferences.
