Unidentified Contaminant/Material Test
 

If you find foreign objects in the process and are interested in identifying such unidentified contaminant/material, iST is at your service to conduct a qualitative analysis. Such service covers tests of both inorganic and organic materials, which are described below.

Analysis of Inorganic Element
This analysis deals with inorganic such as metal elements, acid ions, and halogen ions through conducting both qualitative and quantitative analysis by ICP-OES. The ICP spectroscopy is a spectral analysis with ICP as the source of light emission. ICP-OES stands for Inductively Coupled Plasma Optical Emission Spectrometry. Given its good detection limit and analysis precision, low base interference, and wide dynamic linear range superior to Atomic absorption spectrometry (AA), and easy sample preparation, ICP-OES is broadly utilized in areas of geology, metallurgy, machine manufacturing, environmental protection, and biological medicine.

Analysis of Organic Compounds
The analysis focuses on the compounds with bonding of carbon (C), hydrogen (H), and oxygen (O) such as PP, PS, and PV. Details are described below:
Infrared Spectrometry (IR), also called Infrared Absorption Spectrometry is an analysis that identifies compounds with qualitative analysis through study of the absorption of infrared by constituent molecules in tested materials.

Fourier Transform Infrared Spectrometry (FTIR), on the other hand, generates the infrared spectroscopy of the tested sample by taking Fourier transform of the photocurrent generated in the sample by infrared. The spectroscopy is used to identify the photoelectric and biological properties of the sample in response to infrared. FTIR has the features of: (1) high resolution, with wave number as precise as down to 0.125cm-1;(2) broad spectral range: 4000-400cm- 1
