A Retsch AS 400 sieve shaker is the latest addition to our extensive range of equipment in the Celignis lab.
It can accommodate sieves of up to 40cm diameter, corresponding to a surface area of 1256 square centimetres.
We will use the device for sample preparation and also for Analysis Package P51 (Particle Size Analysis). This allows us to determine the particle size distribution of a range of samples, including wood chips, by following European Standard methods EN 15149-1:2010 and EN 15149-2:2010.

We have now installed a new Carbolite Volatile Matter Furnace in the Celignis laboratory. This allows us to offer the following new analysis packages:
Volatile matter is determined as the loss in mass, less that due to moisture, when a sample is heated at 900 degrees Celsius for a period of 7 minutes. This procedure is undertaken out of contact with air under standardised conditions.
We determine volatile matter according to the procedures outlined in European Standard EN15148-2009 ("Solid biofuels - Determination of the content of volatile matter") and the Carbolite Furnace and special volatile matter crucibles have been specifically designed to satisfy the requirements of this method.

We have now installed and commissioned two new pieces of equipment in our laboratory that allow us to offer the following new analysis packages:
P33 - Ultimate (Elemental) Analysis
P34 - Calorific Value and Elements
We use a Vario MACRO cube elemental analyser for the quantification of the Carbon, Hydrogen, Nitrogen, and Sulphur content of samples. It can process relatively large amounts of sample (over 100mg), allowing us to analyse hetereogeneous samples with improved levels of accuracy and precision.
For the determination of the calorific (heating) value of samples we use a Parr 6200 bomb calorimeter.
The gross calorific value (often referred to as the higher heating value (HHV), gross energy or upper heating value) is determined by bringing all the products of the combustion of a sample back to the original pre-combustion temperature, condensing any vapour produced. The gross calorific value takes into account the latent heat of vaporization of water in the combustion products, and is useful in calculating heating values for fuels where condensation of the reaction products is practical. The determination of the gross calorific value requires a correction based on the sulphur content of the sample.
The net calorific value (often referred to as the lower heating value (LHV) or lower calorific value) assumes that the water component of a combustion process is in the vapour state at the end of combustion.
The net calorific value is more relevant than the gross calorific value when comparing fuels where condensation of the combustion products is impractical, or heat at a temperature below 150 degrees Celsius cannot be put to use. The net calorific value is calculated from the gross calorific value by using corrections based on the oxygen, nitrogen, and hydrogen contents of the sample.
We determine the net and gross calorific values according to the procedures outlined in European Standard EN 14918:2009 ("Solid biofuels. Determination of calorific value"). The Parr 6200 bomb calorimeter has been specifically designed to satisfy the requirements of this method.
We report values on a dry-mass basis as well as on an as-received basis and a dry ash-free basis (providing that the ash content and as-received moisture content of the sample have also been determined). We use the calculations outlined in European Standard EN 15296:2011 ("Solid biofuels - Conversion of analytical results from one basis to another") to carry out these conversions.

A new article, authored by Celignis Managing Director Daniel Hayes has been published in Fuel. The article is entitled "Analysis of the lignocellulosic components of peat samples with development of near infrared spectroscopy models for rapid quantitative predictions" and details the work undertaken to develop near infrared spectroscopy as a rapid analysis method for peat samples.
The article can be accessed on the ScienceDirect website or in Volume 150 of the Fuel Journal.
Abstract: Analytical data and quantitative near infrared (NIR) spectroscopy models for various lignocellulosic components (including Klason lignin and the constituent sugars glucose, xylose, mannose, arabinose, galactose, and rhamnose), moisture, and ash were obtained for 53 peat samples. These included samples with high, medium, and low degrees of humification. Klason lignin was the main constituent and was greatest in the samples classified as being highly humified, with structural sugars the lowest in this class. The total sugars contents of all samples were considered to be insufficient to allow for their use in biorefining hydrolysis processes for the production of chemicals and biofuels. NIR models were developed for spectral datasets obtained from the samples in their unprocessed (wet), dry and unground, and dry and ground states. Typically the most accurate models were based on the spectra of dry and ground samples. However the NIR models for the wet samples still offered reasonable predictive capabilities. All models were suitable at least for sample screening, with the models for total sugars, glucose, xylose, galactose, and moisture suitable for quantitative analyses.

A new article, featuring content written by Celignis director Daniel Hayes, has been published in the "Waste and Biomass Valorization" journal. The article, entitled "Determination of the Higher Heating Value of Pig Manure" describes the use of near infrared models, developed by Daniel Hayes, to predict the Higher Heating Value and other properties of pig manure. The abstract of the article is copied below:
Abstract: The ability of using novel method of near-infrared (NIR) spectra to predict the composition and higher heating value (HHV) of dry pig manure was examined. Number of pig manure solid fractions variously pre-treated samples were collected in Denmark, from different pig slurry treatment plants (using mechanical or chemical-mechanical separation) and then analysed for their energy values. These values were determined by conventional method using bomb calorimetry and also calculated based on ultimate analysis. NIR spectra method was successfully applied and reasonable R2 values were obtained for the independent prediction set for nitrogen, ash, and the HHV. NIR also showed ability for predicting which type of treatment plants the samples came from. In addition, new empirical equations, based on ultimate analyses of pig manure solids used for prediction of the HHV was established.

We are pleased to announce the launch of the Celignis website and the start of our provision of biomass analytical services.
We offer a range of analyses that can provide vital biomass compositional data to help you determine whether your biomass sample is suitable for the production of biofuels, chemicals, or energy.
We maintain the highest standards of accuracy and precision in our work and are suitably sized to provide results in a rapid turnaround.
We are the only company to offer near infrared analysis for the rapid characterisation of biomass samples for their important lignocellulosic properties (e.g. lignin, cellulose, etc.). This rapid analysis allows us to typically provide analytical data within one day of receiving the sample.
We have also developed a user-friendly online system for the placing of orders and viewing of data. It facilitates comparison between your samples and also provides graphical representations of much of the data.
