Qualitative and Quantitative Analysis of Inorganic Substances

Analysis Qualitative and Quantitative Analysis of Inorganic Substances

We perform qualitative and quantitative analysis of inorganic substances, with a focus on metals and environmental standard parameters.
We have particular expertise in component analysis of solid samples using wet digestion techniques and can analyze the specific elements you need to identify.

Overview

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

ICP-MS can simultaneously measure almost all elements in the periodic table. It uses inductively coupled plasma (ICP) as the ion source, where generated ions pass through an interface into a high-vacuum chamber. The ions are separated according to their mass-to-charge ratio and detected by the mass spectrometer (MS). This technique supports qualitative, semi-quantitative, and quantitative analysis, and also enables isotope ratio measurements.

Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)

ICP-OES uses argon plasma at temperatures of 6,000 to 10,000 K as the excitation source. A nebulized liquid sample is introduced into the plasma, where it emits element-specific spectral lines. These spectra are used to identify the elements present, while the emission intensity is used to determine their concentrations.

Atomic Absorption Spectroscopy (AAS)

Atomic absorption spectroscopy utilizes the fact that atoms absorb light at wavelengths specific to each element. When a sample solution is aspirated into a flame, the target elements are atomized by the high temperature. As element-specific light passes through the flame, it is absorbed by the atoms, and the concentration of the element is determined from the amount of absorbed light.

Ion Chromatography (IC)

Ion chromatography separates individual ions using a combination of an ion-exchange resin column and an eluent. The sample solution is carried into the column with the eluent, where ions are retained and subsequently eluted at different rates depending on their characteristics. As a result, the ions are separated while passing through the column, and the separated ions are identified and quantified using conductivity detection or other suitable methods.
