Nebulizers for Thermo Scientific™ PRO ICP-OES
All Glass Expansion concentric glass nebulizers (Figure 1a.) feature our unique VitriCone™ capillary construction delivering you the best possible manufacturing precision. Glass Expansion is the only manufacturer that takes thick walled constant-bore tubing and machines the outside to a uniform aerodynamic shape. This guarantees a uniform sample channel, assuring tolerance to high matrix samples and perfect reproducibility.
Samples with residual hydrofluoric acid (HF) require an inert nebulizer such as the DuraMist nebulizer (Figure 1b.) or VeeSpray ceramic nebulizer (Figure 1c.). DuraMist is a concentric nebulizer made of PEEK. It is ideally suited to ICP-OES for high sensitivity and excellent short-term precision with the highest tolerance to dissolved salts of any concentric nebulizer. The VeeSpray nebulizer is made of high purity Alumina grade ceramic. This parallel path nebulizer is virtually unblockable and provides the best tolerance to large particulates and abrasion-resistance.
All the above nebulizers come with our inert, metal-free DC (Direct Connection) gas fittings as standard.
Spray Chambers for Thermo Scientific™ PRO ICP-OES
The spray chamber is a crucial component of the ICP sample introduction system since it has a profound effect on transport efficiency, precision, and washout. Each Glass Expansion spray chamber incorporates the Helix CT nebulizer interface with ConstantTorque technology, which provides a constant, reproducible, inert, gas-tight seal between the nebulizer and spray chamber each and every time. Glass Expansion offers the following spray chambers to accommodate all kinds of samples and applications.
Single-pass Tracey™ Spray Chamber
- Single-pass Tracey™ version for the highest sensitivity.
- For low volume applications we recommend the single pass Cinnabar™ spray chamber (20mL) option. The Cinnabar's design and low volume are ideal for the reduction of memory and matrix effects and very fast washout.
Double-pass Twister™ Spray Chamber
- Double-pass Twister™ version with central baffle that rejects large droplets from the nebulizer aerosol for best short-term precision and lowest interferences.
- For low volume applications we recommend the double pass Twinnabar™ cyclonic spray chamber (20mL) to reduce solvent load but maintain fast washout.
Inert Tracey TFE Spray Chamber
- Made from totally inert PTFE - impervious to organic solvents and strong acids, even HF.
IsoMist XR Spray Chamber
- The IsoMist XR allows for direct analysis of volatile organic solvents such as naphtha without dilution at a temperature of -25°C, resulting in higher intensities, better precision, and higher accuracy when compared to studies at -10 °C.
HydraMist Spray Chamber
- The HydraMist can simultaneously determine As, Se, Sb, Tl and Hg using hydride generation and non-hydride forming elements using conventional pneumatic nebulization whilst offering more than a 10 fold improvements in detection limits for the cold vapor elements.
Torches for Thermo Scientific™ PRO ICP-OES
We offer a wide range of torches and injectors to suit the ever-growing sample types in today’s market. Whether you’re after the simple to use, standard EMT quartz torch for clean applications or our patented D-Torch for the more aggressive sample matrices, we have a wide range of options fit for every application.
Fixed Standard EMT Quartz Torch
- Suitable for clean applications and laboratories with low sample volume workflows.
D-Torch Demountable Torch
- Optional Ceramic Outer Tube
- Ideal for waste water, brines, fusions, and geological samples where quartz devitrifies rapidly due to the presence of high TDS
- Ideal for tribology (wear metals) and organic application where quartz prematurely fractures due to thermal shock
