Gas chromatography (GC) is a flexible technique that allows separation and quantification of chemical substances found within a complex mixture. For example, it can be used for quantification of bioethanol produced during fermentation of biomass-derived sugars or determination of the fatty acid profile in oilseeds.
Specifically, gas-liquid chromatography (GLC) – involves a sample, containing the chemical(s) of interest, being vaporised and injected onto a chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself contains a liquid stationary phase which coats the walls of the chromatography column. The chemicals being analysed interact with the stationary phase, with each chemical travelling through the column in a different time – this is known as the retention time. The analytical value of GC is based on the comparison of retention times of different compounds.
Technical specification: the gas chromatograph we have is a HP5890 series II capillary GC, equipped with a 100-sample autosampler and flame ionisation detector (FID). The FID allows detection of most organic chemicals or compounds. Electronic data capture and analysis is performed using DataApex Clarity software.

We have an extensive range of pre-processing equipment, see below.
The macerator is capable of reducing solids to small pieces; producing slurries and processing biomass materials with high water content.
Our microbiology laboratory offers a range of equipment allowing users to safely handle, store and work with a variety of aerobic and anaerobic microbes, at ACDP hazard category II level.
Pelletising is the process of compressing light material into the form of a pellet. This has many advantages, mainly by reducing dust in transport and increasing the density of the material being transported.
We have a range of pre-processing equipment to enable us to work with the interesting oils found in seed crops.
Size reduction & grading
Size reduction equipment, such as a cutting mill, a hammer mill or a granulator, with capacities ranging from 4 kg/h to 100 kg/h.
