CETAC now offers the IsoMist Programmable Temperature Spray Chamber from Glass Expansion. The IsoMist provides the benefits of a temperature-controlled ICP sample introduction system in a compact, convenient package.
Peltier Effect Temperature Control
The temperature is electronically controlled using a powerful in-built Peltier device. The user can select any temperature between -10°C and +60°C in 1°C increments to provide the optimum conditions for any application. The rapid response of the Peltier device allows a spray chamber temperature of -5°C to be reached within 15 minutes.
Versatile Computer Interface
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. For regulatory compliance, the temperature vs. 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.
Reduced Oxide Interferences in ICP-MS
By introducing the sample at low temperature, the IsoMist reduces oxide levels (ex. CeO) in ICP-MS, resulting in fewer interferences and improved detection limits. The CeO/Ce ratio is reduced by up to 50% at less than 5°C versus a spray chamber at room temperature (approx. 20°C).
Perfect for Volatile Organics
The temperature can be set as low as -10°C 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 such as naphtha.
Constant Temperature Improves Stability
By holding the spray chamber at a constant temperature, the IsoMist significantly improves long-term stability, increasing the likelihood of calibration checks passing.
Heating Mode Enhances Sensitivity
The sensitivity for many applications is enhanced by running the spray chamber at an elevated temperature, a feature that is particularly important for samples with limited volume.
Proven Cyclonic Spray Chamber
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.
