The Chemical and Physical Chemistry Laboratories of the Industrial Research Institute are very versatile and capable of offering analysis services in many fields ranging from food and beverages, water, raw materials, environmental analysis to engineering and construction materials.
The test methods used comply with the requirements set by international scientific bodies such as AOAC, ASTM, ISO, AFNOR, DIN etc.. depending on the specific material to be tested.
Methods used in chemical analysis range from the more tedious time consuming gravimetric analysis to titrimetric, colorimetric and more instrumental testing. The trend to turn into instrumental chemistry is increasing everywhere and our laboratories are following up with this trend.
The equipment available at the wet and physical chemistry laboratories is:
- High Performance Liquid
Chromatography (HPLC) with UV/VIS and Fluorescence detectors
- Optical Emission Spectrometer (OES) multi channel,
- Gas Chromatographs (GC) with four different detectors FID, ECD, TCD and NPD
- Gas Chromatograph linked to a tandem Mass Spectrometer (GC/MS5)
- Fourier Transform Infra Red Spectrometer (FTIR) with wide range of accessories for analysis of solids, powders, liquids, oils and gases
- Atomic Absorption Spectrometer (AAS)equipped with flame and flameless atomizers as well as hydride generation and cold vapor chamber (for Mercury analysis) analysis
- UV/VIS Spectrometer
- Flue gas analyzer for on-site stack emission and process measurements
- Polarimeters
- Enzyme-linked Immuno Assay (ELISA) reader
- Bomb Calorimeter
- Refractometers
- And other routine analytical and sample preparation instruments

The aims of the analysis conducted at the
IRI’s wet and physical chemistry laboratories are mainly:
- Monitoring of pesticide residues in food, soil and water
- Detection and determination of other persistent organic pollutants (POPs) in food, soil and water, such as Polynuclear Aromatic Hydrocarbons (PAH), Polychlorinated biphenyls (PCB’s), solvents, etc.
- Trace metal analysis in food, water and soil
- Full elemental analysis of steels, aluminum, lead, copper and nickel alloys
- Determination of causes of defects in defected products
- Quality Control of raw materials, intermediate and final products
- Nutrition labels of food products and beverages
- Compliance of goods with specifications and product certification
- Estimation of causes of damage to exported goods, e.g. sea water contamination, heat exposure etc.
- Study of quality of concrete such as cement content, potential reactivity, etc.
- Monitoring and analysis of liquid, gas and solid effluents from industrial and municipal facilities
- Determination of contamination by radiation
- Analysis of packing and packaging materials
- Environmental analysis
- Others
