Analysis Business

From base metals to minor metals.
We analyze valuable resources on behalf of our customers.

We analyze and evaluate resources contained in objects of any type, including molded items, products, scraps, waste liquid, sludge, and catalysts. We can evaluate minute and fine samples and handle toxic substances with a wide range of analyzers. In addition, we respond to short delivery times with our abundant experience and technology cultivated over the years. We contribute to labor savings and cost reduction for customers in a wide range of fields. Furthermore, we can reduce the amount of industrial waste, leading to environmental conservation.

Quick and precise because we are Asaka Riken.

Service features

Analyzed items and types

Purity analysis of gold

Recovered and recycled gold bullion is needed to guarantee its quality based on established standards. Asaka Riken makes full use of know-how and equipment analysis accumulated over years, and we measure the concentration of impurities.

Evaluation of minor and precious metals in boards and scrap

Scrap generated by customers from various industries contain valuable metals. Understanding their composition and content is an important factor in these recycling processes.

Evaluation of valuable metals in sludge

Some sludge treated as industrial waste often contains useful metals, depending on the source. Sludge composition evaluation allows not only useful metals to be recycled, but also an important evaluation that also leads to the reduction of industrial waste.

List of owned analyzers

Inductively coupled plasma optical
emission spectrometer (ICP-OES)

ICP-OES qualitatively and quantitatively analyzes trace elements contained in solutions.
Wavelength dispersive X-ray fluorescence spectrometry (WDX)

WDX qualitatively analyzes the characteristic X-rays emitted from a substance irradiated with X-ray.
Ion chromatograph (IC)

IC qualitatively and quantitatively analyzes anions in solutions.
Scanning electron microscope energy dispersive X-ray spectrometry (SEM-EDX)

SEM-EDX identifies information on what kind of element the sample surface is composed of and its proportion.
Ultraviolet visible spectrophotometer (UV-Vis)

UV-Vis estimates the chemical structure of substances between the absorbance and wavelength of irradiated light.
Fourier transform Infrared spectroscopy (IR)

IR identifies organic compounds (liquid or solid samples.)
Inductively coupled plasma mass spectrometry (ICP-MS)

ICP-MS conducts Qualitative and quantitative analysis by measuring the unique mass number of elements.
