Optical Emission Spectrometer
More Precise Analysis Achieved with a High Resolution Spectrometer
Use of a diffraction grating with a wavelength range suitable for ferrous or non-ferrous applications in Paschen-Runge mounting of 1000 mm focal length offers high-resolution measurements over a wide wavelength range. More precise analysis becomes possible by reducing the effect of spectral interference.
Stable and Proven Vacuum Monochromator
Phosphorus and Sulfur, important elements for the analysis of materials, have spectral lines in the vacuum-ultraviolet wavelength range lower than 190 nm.
In this wavelength range, oxygen in the air absorbs light, so the removal of oxygen is required. The PDA-8000 uses a proven vacuum monochromator to provide stable spectroscopic analysis.
Light Receptor Condensing System
Light passed through the exit slit is focused by a toroidal mirror on the photosensitive surface of a photomultiplier tube. This optical design enables stable measurement.
High Responsiveness to Changes in the Environment
The spectrometer is made from materials that change little with temperature. In addition, by being located in a thermostatic chamber with enhanced thermal insulation performance, changes in the ambient temperature do not affect the instrument, permitting more precise analysis. (Ambient temperature 15 to 30 °C, ±5°C/hour max.)
Constant Monitoring of the Discharge Status
A Real-time Energy Monitoring* function monitors the discharge energy consumed between the counter electrode and the sample. The discharge energy is accurately set and controlled, and discharge defects due to the surface condition of the sample can be instantly detected from the discharge energy. The accuracy is improved by eliminating samples with defects from the measurement.
Supporting Diverse Metal Materials
Many metal materials can be analyzed over a wide range of optimal discharge conditions, such as high-energy discharge for metals like steel with a high melting point, or low-energy discharge for metals like lead and zinc alloys with a low melting point, through the use of a newly-developed discharge energy stabilizing excitation unit.
Ultra Trace Analysis of High Purity Materials
Current Regulative Spark* (CRS), capable of stabilizing the current for every pulse, improves analysis sensitivity of trace amounts.
Energy Efficient Design
This energy-efficient spectrometer has a power consumption of 510 W (43 % reduction from our previous Optical Emission Spectrometer).*1 The argon gas consumption has also been reduced by about 45 % as compared to our previous model.*2
*1 For analyzing 15 samples/hour
*2 The consumption for analyzing 150 samples/8 hours in 1 day
Fusion of Hardware and Software
Integrating software with the hardware enables reliable instrument management, from control and diagnosis to maintenance.
The Pursuit of Greater Ease-of-Use, Based on Reliability
A sophisticated, yet operator-friendly design utilizing vast emission spectrometry experience has been produced.
Plots can be set for each sample, which enables more intuitive and easy-to-understand operation.
