Plasma Torch Cleaning Method of Inductively Coupled Plasma Emission Spectrometer

摘要

The present invention relates to a method for cleaning a plasma torch of an inductively coupled plasma light emitting spectrometer for elemental analysis, by maximizing the cleaning power of the torch by using a cleaning solution having excellent solubility in a composite oxide containing carbon attached to the torch. The purpose of the present invention is to provide an excellent cleaning method that can maximize the work efficiency by not only smoothing the generation of smear but also preventing the high frequency work coil damage and work safety caused by the extension of the torch and electrical short circuit.;The present invention provides a method for cleaning a plasma torch of an inductively coupled plasma light spectrometer, including acetone: 100-200 ml / l, hydrochloric acid: 200-300 ml / l, sulfuric acid: 500-700 ml / l, and potassium dichromate: Preparing a cleaning liquid that is formulated at 30-40 g / l; Immersing the plasma torch to be cleaned in the cleaning solution prepared as described above, heating the cleaning solution to 50-80 ° C., and maintaining the temperature at the temperature for 1-2 hours to perform the first cleaning; Second cleaning by dipping the first cleaned plasma torch in acetone as described above; Rinsing the ultra pure distilled water with the secondary cleaned plasma torch as described above; And a plasma torch cleaning method of an inductively coupled plasma light spectrometer comprising the step of drying the rinsed plasma torch for 30-60 minutes at 90-100 ° C.
