Pyrex Concentric Nebulizer K-Type 3mL/min 30psi
A Concentric Nebulizer – K-type nebulizer is a high-solids nebulizer that is designed to operate at a lower carrier flow and has a smaller internal gas cross-section. It is similar to a C-type nebulizer, but it uses 30% less argon flow. K-type nebulizers are available in quartz and borosilicate glass. Glass nebulizers are often used in ICPMS and ICP, while quartz nebulizers are preferred in ICPMS to reduce the potential for sample contamination
Concentric nebulizers are different because they tend to draw liquid samples as they produce the aerosol. Negative pressure at the point of aspiration causes fluid to flow through the sample line without any external pumping action.
Concentric nebulizers can provide excellent sensitivity and stability, particularly with clean solutions. This product is the Pyrex Concentric Nebulizer K-Type 3mL/min 30psi.
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.
When it comes to 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).
