Determination of carbon, hydrogen, nitrogen, sulfur, and oxygen content of an organic sample. CHNS analysis (”LECO analysis”) is performed using a flash combustion method, where the sample is combusted under 25 kPa of O2 at an elevated temperature …

This metal screening analysis includes the semi-quantitative determination of 70 elements. The method can be used, for example, to determine the background concentrations of metals in environmental samples or to study the elemental distribution of unknown …

N2 adsorption analysis to determine specific surface area and pore size of solid materials.

Determination of the acid-insoluble and acid-soluble lignin content of biomass samples. A solid biomass sample is hydrolyzed, and the acid-insoluble residue is filtered out …

Determining the content of S, Na, K, Ca, Fe, Cu, Mg, Mn, Si, and P in a wood or pulp powder sample. The sample is microwave-digested using a solution of HF, HNO₃, and HCl before the analysis. The elements are then detected using …

Lignin sample molar mass distribution analysis using size exclusion chromatography (SEC) coupled with a UV detector at wavelength 256 nm. The lignin is dissolved in a suitable solvent before analysis. The SEC system is calibrated with a …

This analysis is used to determine the carbohydrate content of seaweed-based samples. A solid sample is hydrolyzed, the acid-insoluble residue is filtered out, and monosaccharide components are analyzed using ion chromatography. Ash content is determined …

The test determines the ash content of paper, board, and pulp upon being ignited at 525 °C. The results express the mass of the inorganics in your sample.

The test is used to determine the ash content of a solid recovered fuel sample according to EN 15403 or ISO 21656 methods. The ashing temperature is typically 550 °C but …

Determination of the degree of substitution of chemically modified carbohydrate samples with the ³¹P NMR method. Suitable for mono-, di-, oligo- and polysaccharides. Price includes sample preparation through …

Determination of the amount of water-soluble chloride in solid matrices. Chloride is extracted from the dried sample with water in a single-stage shaking test at room temperature (20 ± 5°C) …

Lignin sample ash content measurement at 525°C. The result is expressed as a mass percentage of the ash from the initial sample on a dry matter basis.

Analysis of the sugar content of seaweed-based solution samples. First, free monomeric sugar components are determined from the solution using ion chromatography. Then, the sample is acid hydrolyzed and the monosaccharide components are analyzed …

The chemical oxygen demand (COD) of pulp process liquid is measured according to the ISO 6060 standard to evaluate the environmental burden of the water sample. The sample must be kept at a temperature …

The Kappa number describes the lignin content or bleachability of pulp. With this test, the kappa number is determined as per the ISO 302 standard, which applies to all kinds of chemical and …

During this lignin carbohydrate analysis, the lignin sample is first hydrolyzed, after which the acid-insoluble fraction is filtered and monomeric sugars are analyzed with ion chromatography. Monomeric sugars included in the analysis are glucose, …

Metal analysis package for a lignin sample including the following elements: Al, Cd, Co, Pb, Hg, P, Na, Zn, Sb, Ca, Cu, Mg, Mo, K, Ti, As, Cr, Fe, Mn, Ni, Si and V. The analysis is performed with ICP.

Determination of selected metals (Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Zn, V) in oil or solvent samples using high-resolution ICP-MS (ICP-SFMS) technique. …

Determination of free lignocellulosic monomeric sugars (glucose, mannose, galactose, xylose, arabinose) from the solution using ion chromatography. The results are reported as mg/ml of each monomeric sugar in the sample.

Iodine content measurement from solid seaweed samples.

With this test, the pH of water extraction (hot or cold) from a paper, board, or pulp sample is measured. The extraction is performed …
