Introduction of Analysis Machines

Optical Emission Spectrometer

Optical Emission Spectrometer is an indispensable machine for a lot of steel industries and manufacturers to manage product quality since the machine can analyze elements in metals quickly and accurately. General citizens can use it after several days training. Uses argon gas.

*Example of elements that can be analyzed: B, C, Al, Si, P, S, Ca, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Nb, Mo, Sn, Sb, Ce, W, Pb (22 elements)

X-ray Fluorescence Spectrometers

X-ray Fluorescence Spectrometers can analyze all elements from sodium (N) to uranium (U) qualitatively and quantitatively in a solid, powder, and liquid quickly and accurately without destroying them. Uses liquid oxygen.

*Example of elements that can be analyzed: Mg, Si, P, S, K, Pb, Mn, Cu, Zn, As, Br, Cd, Ag, Pt, Au, Hg

Portable X-ray Fluorescence Analyzer

Portable X-ray Fluorescence Analyzer can be used whenever you want since it is portable, although you cannot get lower tolerances with this. You need permission from the labor standard inspection office when you use it. Most suitable for classification of steels and non-ferrous.

*Example of elements that can be analyzed: Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ag, Sn, Sb, Hf, W, Ta, Re, Pb, Bi

Introduction of Radiation Detector

We secure safety by monitoring with the Radiation Detector to make sure that there are no radiation sources (elements that artificially made for industry) or radiation materials mixed up in scraps.
