ANALYSER OF SPECYFIC SURFACE AREA Sorptomat QUADRASORB SI,Producer: Quantachrome Instruments (2009)

 •Measurement conducted in an environment of liquid nitrogen and consist on the adsorption of nitrogen (gas) on the surface of the solid material.
•Possible use of adsorbates: nitrogen, argon, CO2.
•We can measure surface of: soil, mineral, plants materials, food materials, chemicals, building materials.
•Possible measurements:
•Specific surface >0,05 m2/g.
•Porosity: volume of pore < 0,05 m3/g, value of pore (5-200nm).

LIOPHiLYzER Alpha 1-4 LSC, Producer: Martin Christ Gefriertrocknungsanlagen GmbH (2009)
Freeze-drying is used for thermolabile products.Applications:

 •Compaction and drying substances
•Production of freeze-dried food
•Production of enzymatic proteins
•Determination of ash content
•Incineration of samples (e.g. soil, plant) in order to further wet mineralization in solutions of mineral acids. Mineralization of this type is essential in the analysis of metal content by atomic absorption spectrometry
