Technical advantages
Comprehensive analysis for the elements in most metals with the full spectrum detection
Based on the CCD detector with the full spectrum detection technology, the instrument can comprehensively detect the spectral lines of the most of the elements in the metal samples, and carry out analysis for  multi-matrix and multi-elements easily. Therefore, it is convenient and inexpensive to install and add the matrix, channels and analytical program in Skyray or customers’ laboratory
Professional test solution
With long experience in analysis technology service, Skyray Instrument provides users with the sound solutions for the analysis of ferrous and non-ferrous metal.
The analysis programs in our solution are designed according to the classification of metal grade, meeting the various test demands of users perfectly.
The analysis programs are factory-calibrated with international or national standard samples, and have been fitted and corrected by professional software.
Just using a few pieces of the standardization samples supplied by Skyray, the user can carry out the routine calibration easily.  So it is unnecessary to purchase a large number of standard samples for the analysis program.
Top international suppliers provide the core components
Dispersive device—The grating manufactured by CARI ZEISS in Germany ensure the excellent resolution.
Detector—CCD manufactured by TOSHIBA in Japan ensure the detection of spectrum sensitive and low noise.
Optical lens is manufactured by CARI ZEISS in Germany;
Optical fiber is manufactured by Agilent Technologies in America.
Excellent thermostat system for the polychromator
The thermostatic chamber is configured with a feedback heating device and the highly efficient thermal insulating layer, ensuring the temperature of the polychromator.
The thermostatic chamber suppress the drift of optical path due to the slight changes in the dimensions of the mechanical components in different temperatures. Meanwhile, the constant temperature is beneficial to the  performance of photoelectric devices.
Test examples
There are two kinds of sampling for spectrochemical analysis: the melt sampling and the product sampling. In the melt sampling, the metal liquid is injected into the mold and solidify into a solid sample. In the product sampling, the size and shape of the sample should be considered to judge whether cutting it or not.
Reference standards
ISO 14284 Steel and iron—Sampling and preparation of samples for the determination of chemical composition
ASTM E 1806 Standard Practice for Sampling Steel and Iron for Determination of Chemical Composition
ASTM E 716 Standard Practices for Sampling and Sample Preparation of Aluminum and Aluminum Alloys for Determination of Chemical Composition by Spectrochemical Analysis
For the high hardness metal samples(such as steel, Nickel, Cobalt alloy), grind the surface with the grinding machine; for the low hardness metal samples( such as Aluminum, Copper, Zinc, Magnesium alloys),  turn the surface with  the lathe. The treated surface should be flat and smooth with scratches in the same direction.
Place the sample on the spark stand and start the analysis process by operating the software. After completing the test, all the results of the customized elements are displayed simultaneously. The time of a single procedure is less than 40 seconds, and analyzing the same sample for the three times is  genegrally recommended .
