The compact stationary floor-standing single-matrix optical emission spectrometer GS1000-II on PMT (Hamamatsu photomultiplier tubes) is designed for fast and accurate express analysis.
With its rugged design and simple operation, it is ideal for use in a factory for both incoming inspection and material inspection.
In order to ensure independence from the external conditions surrounding the spectrometer, the detectors (photomultipliers) and the integrating system are placed in a thermally stabilized vacuum chamber.
Analytical capabilities cover the accurate analysis of short wavelength elements such as carbon, phosphorus, sulfur and nitrogen in steels and cast irons and phosphorus in aluminium.
Like all OBLF instruments, electrical sparks are generated by a digital gate pulse generator, with the ability to easily set the best possible excitation parameters in combination with a short analysis time.
Minimal maintenance required due to open design and self-cleaning spark stand. It features a patented argon supply system optimized to keep argon consumption to a minimum, resulting in very low operating costs.
