• Equipment Used At Celignis
    For Analysis and Processing


NIR Spectrophotometer

A FOSS XDS NIR device. It has a solid content module that can allow for samples of a heterogenous particle to be analysed.

Ion Chromatography

A Dionex ICS-3000 system that is equipmed with electrochemical, conductivity, and ultraviolet-visible detectors.

UV-Vis Spectrophotometer

A HP 8452A Ultraviolet-Visible spectroscopy device that is used for the determination of the acid soluble lignin concentration of the acid hydrolysate of samples.

Elemental Analyser

A Vario MACRO cube elemental analyser is used for the quantification of the Carbon, Hydrogen, Nitrogen, and Sulphur content of samples.

Bomb Calorimeter

We use a Parr 6200 bomb calorimeter to determine the gross and net calorific value (higher and lower heating value) of samples.

Volatile Matter Furnace

We use a Carbolite Volatile Matter Furnace to determine the volatile matter and fixed carbon contents of samples.

Gas Chromatograph with Mass Spectrometer (GC-MS)

Our lab has an Agilent 6890 gas chromatograph (GC) coupled to an Agilent 5973 mass selective detector (Mass Spectrometer).

Biochemical Methane Potential (BMP) Unit

We use an automated device, developed by Anaero Technologies, to determine the biochemical methane potential of biomass.

Ash Melting Furnace

Our Carbolite CAF G5 BIO ash melting furnace can determine the characteristic ash deformation temperatures for biomass.

Inductively Coupled Plasma (ICP-OES)

Our lab is equipped with an Agilent 5110 ICP-OES which we use for the analysis of the major and minor elements in biomass and ash.


Solvent Extractor

Dionex ASE-200 devices are used to determine the extractives (water-soluble, ethanol-soluble) contents of biomass samples.

Microwave Digestion System

For several analysis packages we use a CEM MARS 6 microwave digestor to prepare extracts/digests for analysis.

Sample Mills

A Retsch SM2000 heavy duty mill is used for processing larger samples and a FOSS Cyclotec 1093 mill for further particle size reduction.

Muffle Furnace

A Nabertherm furnace is used for the determination of the ash content of samples and also in the analytical protocol for determining Klason lignin content.

Sieve Shaker

A Retsch AS 400 sieve shaker is used for particle size analysis and to ensure samples are of a suitable particle size for wet chemical and NIR analysis.


An autoclave is used in the protocols for the determination of the lignin and structural sugars (cellulosic and hemicellulosic) contents of samples.

Moisture Oven

We use a Memmert UF260 oven to determine moisture content according to standard EN methods of analysis.

Incubated Shaker

This is used in analysis packages involving enzymes, for example in the enzymatic hydrolysis of lignocellulosic biomass.

Deionised Water Unit

An Elga Purelab-Option-Q unit is used for obtaining high-purity water for our analysis methods and ion chromatography system.
