Services of material and product testing
According to LVS ISO 8301-2001-A1-2011 Thermal insulation. Thermal resistance and determination of related properties in steady conditions. Device of thermal flow measurement.
Testing of materials in climate chamber, simulating different types of impact of environment on them.
Services of biosystem laboratory
Measurements are made in small volumes (100 ml), average volumes and bioreactores (5L and 135L) with continious monitoring of environmental conditions and gas composition. BMP test takes 20-30 days, in the future results are planned to get faster, using mathematical models.
Anaerobic fermentation is possible to do in bioreactors (5L and 135L), in real conditions researching optimal relation of raw materials, regimes of injection, changes of gas composition, pH stability, withstanding time of optimal substrate and other parameters.
Concentrations of gas, volatile fatty acids, long chain fatty acids are analyzed during measurements, to determine processes in bioreactor.
It’s possible to determine both heavy metals in substrate and digestate (also other briought in samples from client ) and its method efficiency of concentration reduction.
Gas Chromatography Analysis
Lab provides analytical testing using Gas-Liquid Chromatography (GC-LC) technique, including selective and highly sensitive detection of trace and molecular species-specific volatile compounds, like Fatty acids methyl esters, Alcohols and Eters, etc.
Gas chromatography detectors:
- Flame Ionization Detection, (GC-LC/FID)
Liquid Chromatography Analysis
Lab provides High Performance Liquid Chromatography (HPLC) and separations laboratory capabilities for advanced and routine analysis. Liquid chromatography allows for selective and highly sensitive detection of trace and molecular-species (Polyphenols, Anthocyanins; Glycosides; Flavonoids; Carotenoids, Amino acids, Organic acid and Glycols, etc.).
HPLC detectors:
- Fluorescence detector RF-20A xs;
- Diod array detector (DAD) SPD-M40.
