is isolated from any temperature fluctuations within the laboratory, whilst temperature extremes (cooling or heating) can be used to optimize specific analyses.
Cooled spray chambers are commonly used for the analysis of volatile solvents. By cooling a solvent the vapor pressure is lowered, thereby reducing the amount of solvent reaching the plasma and enabling greater plasma stability. This also has the advantage of decreasing the background signal produced by matrix-based emissions. Conversely, high temperature spray chambers are used for the analysis of low volume samples, where low uptake rates are typical y used. Low sample uptake rate can reduce sensitivity; by heating the spray chamber, more sample aerosol is transported to the plasma thereby increasing sensitivity.
Figure 4. IsoMist
The IsoMist is a solid state Peltier temperature-controlled spray chamber which integrates seamlessly with the Thermo Scientific iCAP 7000 Series ICP-OES with dedicated models for both radial and duo instruments. The IsoMist control is managed by a standalone, one screen, user-friendly software package. When coupled to the iCAP 7000 Series ICP-OES, the IsoMist fits within the introduction area of the instrument and does not use valuable lab space.
The use of an Ultrasonic Nebulizer (USN) in conjunction with an ICP-OES has long been

detection limits. Conventional pneumatic
nebulizers are general y only 2 to 3% efficient under normal operating conditions. The CETAC U5000AT+ Ultrasonic Nebulizer converts more of the liquid sample into a usable aerosol, with an efficiency of 10 to 15%.
The CETAC USN couples to the iCAP 7000 Series ICP-OES using the nebulizer push fit connectors for the USN gas flow and coupling the sample flow directly to the torch. This al ows for changeover from the standard sample introduction kit to the USN, in seconds.
The use of the CETAC U5000AT+ USN is a simple and efficient way to gain an average 12 fold improvement in sensitivity over a full range of elements.

analytical performance required for these elements is often difficult to achieve using
a standard sample introduction setup. The analytical performance of these elements can be enhanced by the use of a hydride generation sample introduction system.
The iCAP 7600 ICP-OES spectrometer has a dedicated continuous flow hydride generation accessory which is a combined reaction chamber and GLS. The continuous flow of samples and reagents has a self-cleaning effect upon the system, improving sample throughput. The efficient design of the GLS provides greatly improved sensitivity for the hydride-forming elements.
The accessory utilizes the four channel peristaltic pump with separate channels

and the fourth to remove waste from the system. The samples and reagents are mixed and a carrier gas (in this case argon) is introduced into the GLS. The solution then passes in to a chamber packed with glass beads to provide a large surface area for the separation to take place. The excess liquid is pumped to waste and the gaseous hydride is transported to the plasma via a transfer line.
With the simple addition of the hydride generation accessory, the lower working range of the iCAP 7000 series can be extended to sub-ppb levels for the hydride-forming elements.
