Abstract

The paper concerns the development of an optical emission spectrometer with a helium microwave rotating plasma as the excitation source which is an alternative to ICP spectrometers. In the new solution helium is used as the plasma and carrier gases, which helps to determine elements such as halogens and some non-metals. The new system should demonstrate decreased operating costs i.e. the flow of 1L He/min compared to about 15L Ar/min for ICP. Its spectral range is within 165 nm - 840 nm, sensitivity at the level of ppb and spectral resolution is equal to 0.01 nm. The system uses a set of two photomultipliers for VIS and UV regions. The entire spectrum is collected during a single rotation of the diffraction gratings. The paper describes the collection of algorithms developed to decrease noise and smooth spectral data.
