Quartz, Concentric Nebulizer, K-Type – Ar Low-Flow.
There’s a lot to unpack in that product name. So, just what does it all mean? Let’s start at the beginning.
A concentric nebulizer has a central capillary that contains liquid, and an outer capillary that contains gas. The gas pulls the liquid into the gas stream, breaking it into a fine mist as it moves through. This type of nebulizer uses the Venturi Effect to produce an aerosol.
The Function of the Nebulizer in ICP.
The function of the nebulizer in inductively coupled plasma–mass spectrometry (ICP–MS) is to convert a liquid sample into an aerosol for introduction into the plasma.
The aerosol then passes through the spray chamber and into the plasma, where the sample’s atoms emit light wavelengths that the instrument measures to determine their concentrations.
Regarding the three types of concentric nebulizers, recent studies indicate that the aerosol generation mechanism for the A-type nebulizer is more efficient than for C and K-type. C-type and K-type nebulizers function similarly, but K-type nebulizers use 30% less argon flow than C-type nebulizers.
