Troubleshooting can show what almost all materials contain

Organic and inorganic compounds, surfaces, elements and much more can be identified using the troubleshooting technology used. FT-IR, light microscopy and SEM / EDX are most common but also GC-MS, separation techniques are also used to solve the problems that processes and products encounter.

Almost all types of samples can be studied and examples of some are: Identification of compounds in solid or liquid form without sample preparation. The analyzes are both qualitative / quantitative. It is useful in connection with problem solving, complaints, support to end customers and quality control of various raw materials.

Types of samples: Pulp, paper, cardboard, scrapes, dots, rubber cloth, printed end product, solutions, oils, smears, incubators, piglets.

Various organic compounds: Polymers, biomolecules (lignins, carbohydrates, oligosaccharides, polysaccharides, cellulose, vitamins), aromatic compounds, aliphatic compounds, hydrocarbons.

Different molecular groups: Alkanes, alkenes, arenes, alkynes, arenes, esters, carboxylic acids, alcohols.

Inorganic compounds: Carbonates, carbides, organometallic, complexes, minerals, halides, sulphates.

Examples of materials: scrapes, dots, rubber cloth, printed end product, solutions, incrustations, metals.

Things to keep in mind when sending your samples:

Scrape in a jar when sampling

Do not mark too close to the defect / problem

Exposure is carried out at RISE in Örnsköldsvik

Send references
Process and functional chemicals / materials
- Good reference test to compare with problem / bad test

Light microscopy quickly shows small details

With light microscopy, you can quickly get an overview of the problem and all images are displayed in color. It is often used in connection with product development, problem solving and support to end customers. To gain an underst…

Scanning electron microscopy sees surface structure and elements

Processes are often warm and humid that create good environments for bacteria, precipitates and other undesirable phenomena that contribute to disruption and degradation of end products. Scanning electron microscopy (SEM/XDS) has …

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…

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.

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.

Troubleshooting gives you solutions to problems

Processes and products are often contaminated for various reasons and lead to driveability problems that create financial and environmental penalties and possible complaints from customers. RISE's solid expertise and equipmen…

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…

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…
