Varian 715-ES ICP-OES

The ICP-OES in our institute is an optical emission spectrometer of the type Varian 715-ES from VARIAN with an radial inductively coupled plasma and a patented VistaChip CCD simultaneous detector combined with an echelle raster. We use the ICP-OES for measuring major and trace elements in solution (mainly in 3% HNO3) or couple it to a femtosecond laser. Figure 2 shows elements that can be detected with the OES. The detection limits are different for each element, they are in the range of around 0.05 to 500µg/L. For precise determination of low trace element concentrations, the ELEMENT XR is available at the institute.

A reliable CETAC ASX 510 autosampler is available for high sample numbers. The ICP-OES is working with a 2 ml conical quartz glass nebulizer, a cyclone spray chamber, and torches made of quartz glass.
