The IsoMist Programmable Temperature Spray Chamber, provides the benefits of a temperature-controlled ICP sample introduction system in a compact, convenient package.
The temperature is electronically controlled using a powerful inbuilt Peltier device. You can select any temperature between -10C and +60C in 1C increments to provide the optimum conditions for any application. The rapid response of the Peltier device allows a spray chamber temperature of -5C to be reached within 15 minutes.
For maximum convenience, the IsoMist can be controlled from your PC via a Bluetooth® wireless interface or a standard USB network connection. The spray chamber temperature can be monitored through a temperature versus time plot on your PC screen. And, for regulatory compliance, the temperature versus time data file can be saved with your results. If these features are not required, once the temperature has been programmed, the IsoMist can be run in stand-alone mode without a PC connection.
By introducing the sample at low temperature, the IsoMist reduces oxides as shown in Figure 2, resulting in fewer interferences and improved detection limits.
The temperature can be set as low as -10C to reduce the solvent load on the plasma and allow the straightforward ICP-MS or ICP-OES analysis of even the most volatile organic solvents, as shown in Figure 3.
By holding the spray chamber at a constant temperature, the IsoMist significantly improves long-term signal stability, increasing the likelihood of calibration checks passing. Figure 4 shows the emission signals over 3 hours with the temperature held at a constant 21C compared with a standard system at ambient temperature.
The sensitivity for many analyses is enhanced by running the spray chamber at an elevated temperature, a feature that is particulary important for samples with limited volume. The following table shows that the detection limit with a sample uptake of 20uL/min is better at 60C than 21C and is almost as good as that obtained with a standard system running at 21C with a sample uptake of 2mL/min.
The IsoMist incorporates the proven Twister cyclonic spray chamber, combining excellent sensitivity and precision with exceptionally fast washout. The Helix nebulizer interface has zero dead volume and provides for convenient nebulizer insertion and removal. This system is compatible with the full range of Glass Expansion nebulizers.
The compact design includes a rugged, low maintenance, chemically-resistant polypropylene housing. It provides a much more convenient alternative to a jacketed spray chamber with an external chiller because it does not require an external source of coolant. It is compatible with almost all ICP-MS and ICP-OES models.
The IsoMist can be used with PFA or quartz spray chambers in addition to the standard glass Twister spray chamber. Please contact firstname.lastname@example.org for information on suitable PFA or quartz spray chamber for your IsoMist.
The IsoMist can also be ordered with a PFA or quartz spray chamber installed in place of the standard glass spray chamber. Simple add a "P" for PFA or a "Q" for quartz to the part number for the standard kit, eg. KT-1010P for PFA or KT-1010Q for quartz.
The IsoMist can be configured with a low volume (20mL) Twinnabar spray chamber for applications with limited sample volume. Note that a special IsoMist version is required - the Twinnabar cannot be used in the standard IsoMist. Please contact email@example.com for full details.
We have established an IsoMist Kit for common ICP-OES and ICP-MS models. Each kit contains the IsoMist module, encapsulated Twister spray chamber, torch interface and mounting bracket (if required). Please select the kit to match your ICP from the following:

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 iCAP 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 5degC 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.
