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.
How Are A, K, and C-Types Different?
A-Type
The A-type is ideal for small sample consumption and low detection limits. A-type nebulizers are more efficient at nebulization than C-type and K-type nebulizers.
C-Type
The C-type is best for large sample loads and high levels of dissolved solids. C-type nebulizers feature an internal sample capillary slightly recessed to the nebulizer nose. This design results in a more consistent aerosol and a higher tolerance for dissolved solids than the A Type. The C-type nebulizer operates at 1 L/min Argon at a pressure of 30 or 50 psi and sample uptakes of 1 mL/min, 2 mL/min, 3 mL/min, or Microflow (0.1 – 0.4 mL/min).
K-Type
The K-type nebulizer is suitable for low carrier flow and small internal gas cross-sections. It operates similarly to C-type nebulizers but with a 30% lower argon flow (0.7 liter/minute compared to 1 liter/minute used by the C-type).
