Product Information

Improve Analytical Stability

On the IsoMist, the spray chamber temperature is accurately controlled through an improved thermodynamic design using a multi-stage Peltier device. The spray chamber temperature is settable in 1°C increments from -25°C to 80°C guaranteeing optimum conditions for any application. The improved cooling efficiency of the new multi-stage Peltier design means the IsoMist is ready, sooner and the cool-down time is reduced.

Reduce Oxide Formation in ICP-MS

Using the IsoMist spray chamber at sub-ambient temperature on an ICP-MS, the sample is cooled so less water vapor is transferred to the plasma resulting in lower oxide formation and reduced polyatomic interferences - improving accuracy and detection limits.

Perfect for Volatile Organics

When analyzing volatile organic solvents such as naphtha and gasoline a lower sample introduction system temperature reduces nebulization efficiency avoiding quenching of the plasma from solvent over-loading. With a minimum temperature of -25°C analyzing volatile organic solvents is even easier.

Constant Spray Chamber Temperature

Fluctuations in the lab temperature affects sample viscosity and nebulization efficiency. Maintaining the sample introduction at a constant and stable temperature improves analytical reproducibility, enhances throughput, and lowers operating costs by reducing the need to re-run samples when a calibration verification check standard drifts outside the acceptable limits.

Elevated Sample Introduction Temperatures Enhances Sensitivity

The sensitivity for many analyses can be enhanced by operating the spray chamber at elevated temperatures - especially important for limited sample volumes. Heating the spray chamber also helps with the analysis of viscous samples such as lubricants and edible oils.

Elegant, Ergonomic and Compact

The IsoMist is an elegant, compact, stand-alone system manufactured from materials resistant to attack from acids and solvents commonly used in ICP analysis. By using a peltier to maintain the spray chamber temperature, the messy, noisy and high-maintenance refrigerated circulating baths used with jacketed spray chambers has been eliminated. The compact design means all IsoMist Programmable Temperature Controlled Spray Chambers are compatible with virtually any ICP-OES or ICP-MS.

Application Flexibility and Superior Design Innovation

The IsoMist incorporates Glass Expansion's' proven Glass Twister cyclonic spray chamber design. A Quartz Twister and HF resistant, high-purity PFA Tracey design is also available upon request. All of which are easily interchangeable, allowing for application flexibility should sample matrices change. All of Glass Expansion's' cyclonic spray chambers, including the IsoMist feature the Helix CT™ interface. The Helix CT fitting is completely inert and carefully designed to fix the depth of penetration and torque of the nebulizer seal so that the aerosol produced is optimal. The Helix CT interface is also the only true zero-dead volume nebulizer/spray chamber interface providing unmatched washout efficiencies. These design innovations have provided Glass Expansion spray chamber sensitivity gains, reduced washout times and reduced matrix effects not possible with other spray chambers.

Customer comments

In terms of doing multi element analysis on spirit samples the IsoMist has proved itself to be a very useful tool.

Beverage manufacturer - UK

(In reference to the IsoMist) We are getting around 40% increased sensitivity over what we had before. Also, the QC recoveries for the problem elements B, Al and Zn seem to be much improved.

Health laboratory - Australia

We have all instruments using the Niagara Plus and the IsoMist and have increased efficiencies by up to 40% and over-all quality has also shown improvements, so we are very happy with them.

Minerals laboratory - Australia

So far we are very happy with the IsoMist spray chamber. The detection limits are better and the intensities are more stable from run to run.

Precious metals laboratory - Australia

The IsoMist has significantly boosted our productivity. It is so stable that I need only run a CCV and CCB at the beginning of the day and then start running samples. No need to restandardize daily.

Environmental laboratory - USA.

I've been operating the IsoMist on the 6500 at 27 degrees centigrade ... the improvement in stability has been dramatic ... I am thrilled at the linearity with little shift throughout a complex standardization and sample run.

Precious metals laboratory - USA

The equipment works extraordinarily well. Keeping temperature at 5°C the noise drops to half as much as without the IsoMist. There is no problem at all with temperature stability and the signal is twice as much as the one obtained without the IsoMist.

University laboratory - Spain

I would enthusiastically recommend the IsoMist to anyone trying to minimize oxide formation in ICP-MS.

Government laboratory - USA

The IsoMist was a treat because it took the place of the jacketed spray chamber, the heated bath, delivery tubes, and pump. It also eliminated my worries about leaks in my sample chamber. It is a small, neat package.

Oil company - USA

We are very happy with the performance of the IsoMist.
