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 …

Determination of the total organic fluorine (TOF) content in combustible materials by combustion ion chromatography (CIC). TOF analysis gives …

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 …

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

The molar mass distribution of biomass samples soluble in pure water or organic solvents (DMF, DMSO, and THF) is measured with gel permeation chromatography with a refractive index detector (GPC-RID). The system is calibrated with polystyrene …

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 …

This biomass composition analysis includes the following determinations: Carbohydrate content, Lignin content , Degradation products. During the analysis, …

Classic stable isotope analysis of carbon (13C) with isotope-ratio mass spectrometry (IRMS). The results are reported in the unit VPDB, ‰. The analysis is suitable for various sample materials. Please contact the Measurlabs expert for more detailed …

Gravimetric determination of extractives content in solid biomass. Non-volatile extractives soluble in organic solvents (acetone, n-heptane, ethanol) can be quantified. Other solvents can also be used upon …

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.

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 …

During this biomass carbohydrate analysis, the sample is first hydrolyzed, after which the acid-insoluble fraction is filtered and monomeric sugars are analyzed with ion chromatography or high-performance liquid …

Pyrolysis gas chromatography-mass spectrometry (py-GC-MS) analysis to determine the identity of an unknown polymer sample. During the measurement, the sample is instantaneously heated in an inert atmosphere or vacuum. This causes the …

Particle size distribution (PSD) is determined from transmission electron microscopy (TEM) images. The method is most suitable for small particles of 50 nm or smaller. Depending on particle shapes, the method includes calculating the diameters or …
