Introduction
Introduction
The CETAC Marin-5 Enhanced Nebulizer System is designed primarily
for ICP-AES and ICP-MS. The Marin-5 consists of a pneumatic
nebulizer, a specialized heated spray chamber, and a dedicated
desolvation apparatus.
Sensitivity is improved with the Marin-5 by increasing analyte
transport efficiency and reducing solvent loading to the plasma.
Functionally, liquid sample is pumped or self-aspirated to a pneumatic
nebulizer at an uptake rate of ≤ 0.5 mL/min and an argon nebulizer gas
flow rate of 0.5 to 1.1 L/min. The nebulizer is inserted into a heated
spray chamber to convert a higher percentage of the liquid into an
aerosol. The spray chamber is connected to a desolvation system to
condense most of the liquid in the aerosol and maintain plasma
stability. A built-in three-channel drain pump removes the condensed
sample solvent to waste. Dried sample particles then continue in the
nebulizer gas flow to the plasma, resulting in emitted analyte radiation
(ICP-AES) or analyte ions (ICP-MS).
The nebulizer, spray chamber, and desolvation system are protected by
a secure lid, with access to the nebulizer via a front door. An external
view of the Marin-5 is shown in Figure 1-1.
