MEINHARD DIHEN Direct Injection Nebulizers

100% Transport Efficiency/Specialty Applications

MEINHARD's® Direct Injection High Efficiency Nebulizers (DIHEN) use the HEN nozzle design in a nebulizer which operates within the plasma torch at the base of the plasma. As a result, 100% of the sample is transported to the plasma. The DIHEN are designed to operate a lower sample flow (less than 300 uL/min) with a smaller gas cross-section to obtain higher nebulizing gas velocity, smaller droplets, and the most signal from the smallest volume of sample. The carrier backpressure is 90 psi (620 kPa), 120 psi (830 kPa), 150 psi (1030 kPa), or 170 psi (1200 kPa). In order to ensure that maximum gas velocity is obtained, the operator should select the highest gas pressure with which he is comfortable working, or the highest pressure available for his instrumentation. The complement to gas velocity is a reduction in liquid flow to less than 300 uL/min, where < 100 uL/min is most commonly used with the MEINHARD® DIHEN.

Typically, DIHEN are manufactured in borosilicate glass nebulizers for many routine sample types in ICP-MS.
