ICP-MS (INDUCTIVELY COUPLED PLASMA - MASS SPECTROMETRY)
Brand / Model: Analytik Jena / PlasmaQuant MS Elite
Description: ICP-MS is an advanced analytical instrument used for fast, sensitive, and reliable determination of trace and ultra-trace elements. It enables simultaneous quantitative analysis of multiple elements at ppm, ppb, and ppt levels. The system is widely used in environmental, food, geological, metallurgical, and petrochemical applications.
Operating Principle: The ICP-MS system consists of two main units: Inductively Coupled Plasma (ICP) and a Mass Spectrometer (MS). Elements in the sample are vaporized and ionized in an argon plasma at approximately 10,000 K. Liquid samples are introduced as an aerosol via a nebulizer and spray chamber. Fine droplets are transported into the plasma, while larger droplets are directed to waste. The ionized sample is transferred into a high-vacuum environment through the sampler cone and skimmer cone. Ions focused by the quadrupole are separated according to their mass-to-charge (m/z) ratios and directed to the detector for measurement. This process enables highly accurate qualitative and quantitative elemental analysis.

Application Areas
ATOMIC ABSORBTION SPECTROMETER (AAS)
Brand / Model: Analytik Jena / novAA 800
Description: Atomic Absorption Spectroscopy (AAS) is an analytical technique used for the quantitative determination of trace elements at ppm and ppb levels. This single-element method provides accurate and reliable measurement of elemental concentrations in various sample matrices.
Working Principle: In AAS, the concentration of an element in a sample is determined by comparing the absorbance of the sample with that of calibration standards of known concentrations. The element-specific wavelength is generated by exciting the corresponding element in a hollow cathode lamp, ensuring high selectivity and accuracy.
Depending on the type and concentration of the element to be analyzed, measurements are performed using the appropriate Flame, Graphite Furnace, or Hydride Generation technique.

Microwave Sample Preparation (Digestion) System
Brand/Model: Berghof/Speedwave Xpert
The microwave sample preparation system is a laboratory device used to dissolve solid samples under high temperature and pressure with the addition of acids, enabling preparation of samples for trace and ultra-trace analysis. The microwave technique allows rapid heating to the target temperature; microwave energy causes molecular agitation, which generates heat through collisions between neighboring molecules and accelerates the digestion process. This method is a physical process and does not induce chemical reactions, providing controlled and reproducible sample preparation.
Application Areas:
Food and feed (beverages, animal feed, dairy products, fruits, vegetables, coffee, beer, cereals, etc.) · Environment and geology (soil, sediment, sludge, wastewater, filters/emissions, minerals, concrete, ash, etc.) · Pharmaceuticals and cosmetics (blood, hair, bone, cosmetics, tablets, ointments, etc.) · Technology and materials (polymers, metals, alloys, ceramics, cement, PET, polyester, etc.)
Technical Features:
- Maximum temperature: 260 °C · Maximum pressure: 100 bar · Operation with 230 original Berghof methods ·

UV- GÖRÜNÜR BÖLGE (UV-Vis) SPEKTROFOTOMETRESİ
.
Brand / Model: Jasco / V-730
Description: The UV-Vis (Ultraviolet–Visible) absorption spectrophotometer is an analytical instrument used for quantitative analysis based on the absorption characteristics of molecules or inorganic ions/complexes in solution at specific wavelengths. Concentration determination is achieved by measuring the amount of absorbed light expressed as absorbance.
Working Principle: UV-Vis absorption spectroscopy is based on the decrease in light intensity after a light beam passes through a sample or is reflected from the sample surface. This decrease indicates an increase in the amount of absorbed substance. Many molecules absorb radiation in the UV or visible wavelength regions. The instrument determines the sample concentration by measuring absorbance at a selected wavelength.

FT-IR (FOURIER TRANSFORM-INRED) SPECTROMETTER
Brand / Model: Jasco / FT-IR 6700
Description: FT-IR (Fourier Transform Infrared) spectroscopy is a powerful analytical technique used for structural characterization of organic and inorganic compounds. It enables qualitative and quantitative analysis of solid, liquid, and solution samples, including identification of functional groups and bond structures.
Working Principle: Infrared (IR) spectroscopy is based on the absorption of infrared radiation by a sample. When molecules are exposed to IR radiation, vibrational and rotational motions such as stretching, bending, and twisting of chemical bonds produce characteristic absorption bands. These bands form an IR spectrum that provides structural information about the molecule. Only molecules with a changing dipole moment can absorb IR radiation. Therefore, homonuclear diatomic molecules such as N₂ and O₂ are IR inactive, whereas molecules like HCl are IR active and produce FT-IR spectra.
