Nebulizer, DIHEN (Large Bore)

Large Bore Direct Injection High Efficiency Nebulizer (LB-DIHEN)

The DIHEN is a pneumatic micronebulizer designed to introduce micro-volumes of sample solutions directly into a ICP or ICPMS without a spray chamber.

Applications for DIHEN include ultratrace isotope and elemental analysis of sample types that are of limited volume, toxic, expensive, or that exhibit speciation interferences that cause transport efficiency issues in conventional spray chambers. DIHEN can introduce microvolumes into plasmas at 1- 100 µL/min, with relatively small aerosol droplet size and with nearly 100% use of the sample.

The Large Bore DIHEN is less prone to capillary blockage and optimally operates at lower nebulizer gas pressures compared with the conventional DIHEN.
