IsoMist Kit, Varian 700-ES/Vista Axial

The IsoMist Programmable Temperature Spray Chamber, provides the benefits of a temperature-controlled ICP sample introduction system in a compact, convenient package. The spray chamber 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.

By introducing the sample at low temperature, the IsoMist reduces oxides, 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.

Also, by holding the spray chamber at a constant temperature, the IsoMist significantly improves long-term signal stability, increasing the likelihood of calibration checks passing.
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.

Optional PFA and Quartz Spray Chambers

The IsoMist can be used with PFA or quartz spray chambers in addition to the standard glass Twister spray chamber, or can be ordered with a PFA or quartz spray chamber installed in place of the standard glass spray chamber. Please contact us for part numbers.

Twinnabar Spray Chamber

The IsoMist can be configured with a low volume (20mL) Twinnabar spray chamber for applications with limited sample volume. Note that the Twinnabar cannot be used in the standard IsoMist - a special IsoMist version is required. Please contact us for details.
