Optical emission spectrometer PDA-7000

for metal analysistungstenPMT

Emission spectrometry provides rapid and accurate simultaneous determination of many elements in metals. This technique has been adopted as standard method for metal analysis. The Shimadzu PDA-7000 is high performance optical emission spectrometers, utilizing the PDA method as standard, which enhances the accuracy and reliability of analysis. The PDA method, combined with excellent hardware quality, make the PDA-7000 suitable for any application in metal analysis. They enhance analysis productivity in quality control and process control in the ferrous and non-ferrous metal industries. Features Vacuum Monochromator The monochromator must be held in a vacuum or in a gas-replacement atmosphere to avoid effects due to the absorption of spectral lines such as C, P, S, B, and N by atmospheric oxygen. Shimadzu adopts a vacuum monochromator that is resistant to the effects of temperature fluctuations. It is installed in a temperature-controlled monochromator chamber to achieve extremely stable measurements. New Spark Stand Enhances Stability The structure and materials of the conventional spark stand have been upgraded to considerably enhance analysis accuracy for high-concentration elements (stainless steel and aluminum alloy). It accepts large sample plates, offers greater ease of handling, and enhances durability. Further, selecting the optional stand water-cooling kit (see page 12) restricts the spark stand temperature rise due to electrical discharge during continuous analysis, thereby enhancing the stability of the measured values.
