Analyze metals with low detection levels

RISE specializes in analyzes of forest industry samples. Solid samples such as wood chips, pulp or liquid form such as black liquor.


Manganese causes decomposition of peroxide and therefore impairs the bleaching result, which results in higher peroxide dosage and thus costs. Therefore, it is important to know what manganese content you have in the pulp after the various bleaching steps. On the evaporation side, you often want to know free and total calcium because calcium, together with other things, can cause encrustation and precipitation.

Analyzes of all streams in the recycling show the levels of different metals and where they are in the parts of the recycling cycle. Sometimes mills bring in new firewood or firewood from other purchasing areas and then you want to know if the metal levels are critical.

Sometimes our assignments are purely problem-solving jobs. By combining, for example, analyzes with ICP, FTIR, SEM and light microscopes and our combined experience of existing problems, we can solve even seemingly difficult-to-solve problems.

In the case of analyzes with ICP, the pre-treatment of samples is crucial for a correct analysis result. Since the samples we receive for metal analysis can be both solid, such as chips and pulp, or in liquid form but with a complicated composition such as black liquor, it is important to know how to make a correct digestion of the samples before analysis. An advantage of the ICP is that it is both fast and can detect low levels.



The ICP instrument is an iCAP 7400 ICP-OES and has been supplied by Thermo Scientific.

Analysis of anthraquinone in anthraquinone products and dispersions

Anthraquinone consists of yellow acicular crystals and is a form of dispersion used in the cooking of sulphate pulp to improve yield. To get a consistent quality of the process, it is important to know the exact amount of anthraqu…

Pulp technology

The pulp production plays a central role in the bioeconomy, the transition to a fossil-free society and circular processes. The main part of fiber line is the cooking, where wood is treated with chemicals in order to liberate the …

Identification of various organic and inorganic compounds

FTIR Fourier Transform Infrared Spectroscopy, is mainly used for positive identification of various organic and inorganic compounds in complex samples. Even very small samples, such as dots and stains in pulp and paper, can be stu…

Separation of chemical compounds

Separating and purifying various chemical liquids such as cooking liquids, yeast tanks and black liquor is important in traditional forest industry process liquids and materials, as well as in the biorefinery area.

Analyzes of carbohydrates and anions in cellulose processes

Process control in the cellulose industry is necessary to reduce driveability problems and to analyze carbohydrates and anions, for example oxalate, chloride, sulphite, sulphate and thiosulphate ions, can provide an increased know…

The temperature can affect the viscosity

It is possible to measure viscosity with a temperature-controlled bath to determine the relationship between different temperatures and corresponding viscosity values. For some applications, the effect of temperature on the viscos…

Detect rosin in products

Rosin, a collective name for resin acids, is found naturally in extractives from pine, spruce and larch trees and therefore ends up to a very large extent in the tall oil after cooking. Allergies to rosin are present and we can id…
