This is typically achieved by burning a known quantity of the material in a controlled environment and measuring the heat produced. It is widely utilized in industries such as energy production, fuel testing, and material analysis to assess the efficiency and suitability of fuels, determine their heating capabilities, and optimize processes for maximum energy output.

Our chemical laboratory is equipped with:

  • Combustion calorimeter (C200, IKA)

Processing Technology and Sample preparation

We prepare the raw materials in the appropriate manner for the process to be tested. Our preparation methods include:

Milling

Milling is a mechanical process used to reduce the size of solid materials into finer particles through the application of mechanical force. Typically, it involves the use of specialized equipment such as ball mills or hammer mills to crush, grind, or pulverize materials into smaller sizes. In chemical and physical analytical methods, milling plays a crucial role in sample preparation by homogenizing materials, facilitating uniformity in composition and particle size distribution, which is essential for accurate analysis of properties like chemical composition, surface area, and reactivity.

Sieving

Sieving is a mechanical process employed to separate particles based on their size. It involves passing a mixture of particles through a sieve, a mesh-like device with uniform openings, where smaller particles pass through while larger particles are retained. In chemical and physical analytical methods, sieving is utilized to achieve particle size fractionation, enabling the isolation of specific size ranges for analysis. This technique is crucial for characterizing particle size distribution, assessing sample purity, and ensuring uniformity in materials, facilitating accurate analysis of properties such as particle size distribution, surface area, and porosity, which are vital for optimizing processes and product performance in various industries.

Stirring

Stirring is a mechanical process used to mix substances uniformly by agitating them with a stirring device. Typically achieved using magnetic stirrers, overhead stirrers, or manual stirring rods, stirring ensures thorough blending of components in liquids or powders. In chemical analysis, stirring is crucial for homogenizing samples, facilitating even distribution of solutes, catalysts, or reagents, thereby promoting consistent reactions and enabling accurate analysis of properties such as concentration, viscosity, and reaction kinetics.

Drying

Drying is the process of removing moisture or other volatile substances from a material to achieve a specified level of dryness. It is commonly accomplished through methods such as air drying, oven drying, or freeze drying, depending on the nature of the material and desired results. Drying is an important step in the sample preparation – by eliminating moisture, solvents, or other interfering substances, it ensures the accuracy and reliability of subsequent analyses. Drying is utilized to determine the moisture content, assess the stability of materials, and facilitate precise measurements of mass and composition, thereby facilitating accurate characterization and analysis of different materials.

Our laboratories are equipped with drying cabinets covering the temperature range from ambient to 300°C.

Centrifugation

Centrifugation is a technique used to separate components of a mixture based on their density differences by subjecting the mixture to centrifugal force. It involves spinning a mixture at high speeds in a centrifuge, causing heavier particles to settle at the bottom of the centrifuge tube while lighter particles remain suspended or rise to the top. Centrifugation is employed for various purposes such as separating solids from liquids, isolating specific components of a sample, and purifying substances from impurities.

Our laboratories are equipped with centrifuge ROTINA 420 R (Hettich)

Thermal treatment

Thermal treatment involves subjecting materials to controlled heating or cooling processes to induce desired physical or chemical changes. This can include annealing, calcination, sintering, or quenching, depending on the intended outcome. In chemical and physical analytical methods, thermal treatment is utilized to modify material properties, such as crystallinity, phase composition, microstructure, and mechanical properties, for enhanced characterization and optimization. It enables the investigation of thermal stability, reaction kinetics, and phase transitions, providing valuable insights into the behaviour and performance of materials across a wide range of applications in research, development, and manufacturing processes.

To create optimal process conditions in the range 100 – 1150 °C we use different size and types of muffle and tube furnaces.

Chemical Treatment and Analysis

Digestion

Digestion in analytical chemistry refers to the process through which a sample is converted from a solid to a liquid. This is done by applying reagents, which may include strong acids and bases. Heat is often used to speed up the digestion process, where both the sample and the agent are heated.

Spectrophotometry

Measures the amount of light, primarily focusing on visible light, absorbed by a substance at specific wavelengths. This information is then used to quantify the concentration of the analyte in a solution or liquid – the colour intensity is proportional to the concentration of the compound of interest.

Proper colorimetric/photometric analysis involves three elements: sample preparation and delivery; colorimetry (combining the sample and reagent to produce colour); and photometry (measurement of the resulting colour intensity).

For the photometric analysis, our laboratory is equipped with a spectrophotometer “Nanocolor 500D”(Macherey-Nagel).

Molecular spectroscopy

Molecular characterisation of solids, liquids and powders by FTIR and Raman spectroscopy provides information on the structure and composition of the material. Both methods provide a spectrum that characterises the specific vibration of a molecule – a „molecular fingerprint“.

  • FTIR-spectroscopy using attenuated total reflection technique (ATR-IR):

By measuring the attenuation of infrared light that penetrates into the sample through the internal reflection element, ATR-IR spectroscopy provides valuable information about the molecular structure and composition of thin films, liquids, and solids. It is a rapid, non-destructive technique. This makes it a powerful analytical tool in various scientific and industrial applications.
Our laboratory is equipped with an ATR- FTIR spectrometer “HazMatID Chemical identifier”.

  • Raman spectroscopy:

The inelastic scattering of monochromatic light by interaction with a sample is the basis of Raman spectroscopy. The scattered light undergoes energy shifts corresponding to vibrational modes, which provide detailed information about molecular structure and composition in the form of a Raman spectrum. The method is used to identify inorganic and organic substances, contaminants, and impurities, and to analyse liquids, fibres and very small particles.

 Bruker SENTERRA Raman spectrometer with integrated optical (confocal) microscope is used for Raman spectroscopy analysis in our laboratory.

 

Potentiometry

A technique to measures the voltage of a solution to determine its concentration or activity. It typically involves the use of a potentiometric sensor, such as a pH electrode or ion-selective electrode.

Our chemical laboratory is equipped with:

  • pH Meter (Five Easy FE20 (Mettler Toledo) and IS 2100 L (VWR))

This can include annealing, calcination, sintering, or quenching, depending on the intended outcome. In chemical and physical analytical methods, thermal treatment is utilized to modify material properties, such as crystallinity, phase composition, microstructure, and mechanical properties, for enhanced characterization and optimization. It enables the investigation of thermal stability, reaction kinetics, and phase transitions, providing valuable insights into the behaviour and performance of materials across a wide range of applications in research, development, and manufacturing processes.

To create optimal process conditions in the range 100 – 1150 °C we use different size and types of muffle and tube furnaces.

Fuel Analysis

Ash analysis

A method used to determine the inorganic residue left behind after combustion of organic materials. This process is typically conducted by heating a sample to complete combustion, followed by quantifying the remaining ash content through gravimetric method. Ash analysis is used to assess the mineral composition, purity, and quality of materials. It provides valuable information about the mineral content, presence of impurities, and overall stability of substances for quality control, product certification, and regulatory compliance, aiding in quality control, regulatory compliance, and product optimization processes.

Calorific value measurement

A method used to quantify the amount of energy released during the combustion of a substance. This is typically achieved by burning a known quantity of the material in a controlled environment and measuring the heat produced. It is widely utilized in industries such as energy production, fuel testing, and material analysis to assess the efficiency and suitability of fuels, determine their heating capabilities, and optimize processes for maximum energy output.

Our chemical laboratory is equipped with:

  • Combustion calorimeter (C200, IKA)

Chemical Treatment and Analysis

Digestion

Digestion in analytical chemistry refers to the process through which a sample is converted from a solid to a liquid. This is done by applying reagents, which may include strong acids and bases. Heat is often used to speed up the digestion process, where both the sample and the agent are heated.

Spectrophotometry

Measures the amount of light, primarily focusing on visible light, absorbed by a substance at specific wavelengths. This information is then used to quantify the concentration of the analyte in a solution or liquid – the colour intensity is proportional to the concentration of the compound of interest.

Proper colorimetric/photometric analysis involves three elements: sample preparation and delivery; colorimetry (combining the sample and reagent to produce colour); and photometry (measurement of the resulting colour intensity).

For the photometric analysis, our laboratory is equipped with a spectrophotometer “Nanocolor 500D”(Macherey-Nagel).

Molecular spectroscopy

Molecular characterisation of solids, liquids and powders by FTIR and Raman spectroscopy provides information on the structure and composition of the material. Both methods provide a spectrum that characterises the specific vibration of a molecule – a „molecular fingerprint“.

  • FTIR-spectroscopy using attenuated total reflection technique (ATR-IR):

By measuring the attenuation of infrared light that penetrates into the sample through the internal reflection element, ATR-IR spectroscopy provides valuable information about the molecular structure and composition of thin films, liquids, and solids. It is a rapid, non-destructive technique. This makes it a powerful analytical tool in various scientific and industrial applications.
Our laboratory is equipped with an ATR- FTIR spectrometer “HazMatID Chemical identifier”.

  • Raman spectroscopy:

The inelastic scattering of monochromatic light by interaction with a sample is the basis of Raman spectroscopy. The scattered light undergoes energy shifts corresponding to vibrational modes, which provide detailed information about molecular structure and composition in the form of a Raman spectrum. The method is used to identify inorganic and organic substances, contaminants, and impurities, and to analyse liquids, fibres and very small particles.

 Bruker SENTERRA Raman spectrometer with integrated optical (confocal) microscope is used for Raman spectroscopy analysis in our laboratory.

 

Potentiometry

A technique to measures the voltage of a solution to determine its concentration or activity. It typically involves the use of a potentiometric sensor, such as a pH electrode or ion-selective electrode.

Our chemical laboratory is equipped with:

  • pH Meter (Five Easy FE20 (Mettler Toledo) and IS 2100 L (VWR))
  • Titrator DL77 (Mettler Toledo)

 

Our laboratories are equipped with drying cabinets covering the temperature range from ambient to 300°C.
