Water and environmental analyses
This department focuses on the quantification of elements, anions, cations, nutrients, and other non-organic parameters in water, soil, and air samples.
Elemental Analyses using ICP
Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma–Mass Spectrometry (ICP-MS) are core analytical techniques used for multi-element determination in water, and environmental samples.
Both techniques rely on a high-temperature argon plasma to atomize and excite elements in a sample solution, enabling accurate and simultaneous measurement of a wide range of elements across different concentration levels.
ICP-OES measures the characteristic optical emission of excited atoms and ions and is well suited for the determination of major, minor, and trace elements at mg/L to low µg/L concentrations.

Major anions and cations using UV -spectrophotometry
UV–Vis spectrophotometric methods are commonly applied for the analysis of major anions such as nitrate, nitrite, sulfate, phosphate, fluoride, chloride, COD and TSS, as well as major cations including ammonium and iron.
In many cases, the analytes are converted into stable-colored complexes using selective reagents, while in other cases direct absorbance measurements are used. These methods are particularly suited for routine monitoring due to their simplicity, cost-effectiveness, and rapid analysis time.

Oxides’ analysis using WDXRF
Wavelength Dispersive X-Ray Fluorescence (WDXRF) is a robust and widely accepted analytical technique for the quantitative determination of major and minor oxides in geological, mineral, cement, ceramic, and environmental solid samples. The use of wavelength dispersion provides high spectral resolution, excellent accuracy, and low detection limits for oxide-forming elements.
WDXRF is particularly suited for the determination of major oxides, including SiO₂, Al₂O₃, Fe₂O₃ (total iron), CaO, MgO, Na₂O, K₂O, TiO₂, MnO, P₂O₅, and SO₃, as well as selected minor and trace oxides depending on sample preparation and calibration.
