Example of sample type:
High performance liquid chromatography (HPLC) is an increasingly important analysis tool to be used for traditional process liquids within the forest industry as well as the biorefinery field. MoRe Research is at the forefront and is able to analyse a number of different compounds with the aid of HPLC.
HPLC is used for analysis of a number of compounds:
Organic acids: levulinic acid, ethanol, glycerol and lactic acid, formic acid, acetic acid, furan derivatives hydroxymethylfurfural (HMF) and furfural. We can also measure organic acids in black liquor.
Optical brighteners are expensive and should preferably stick to the paper surface and not end up in the effluents - not in the least for environmental reasons. HPLC analyses can determine the amount of optical brighteners in paper and in different process flows around the paper machine. When studying competing brands it is often possible to determine if the optical brightener is of di, tetra or hexa type.
One of the detectors is a Dioade Array Detector (DAD), which displays a complete UV-VIS spectrum of each compound. High molecular weight material can be analysed in the same system, providing the molecular weight distribution for e.g. lignin and other polymers. We can also do molecule weight distsribution on hemicellulose. Overall MoRe's HPLC system is an excellent tool for biorefinery studies as well as process studies within the forest industry.
