Do you need to characterise the chemical composition of your material? FTIR (Fourier Transform Infrared) spectroscopy is a key technique for material analysis. At RISE, we offer not only standard FTIR set-ups but also advanced methods such as micro-FTIR imaging spectroscopy and micro-FTIR imaging spectroscopy for analysis of microplastics.

Spectroscopic material analysis

FTIR spectral fingerprints of many organic compounds are unique, which is why FTIR spectroscopy is widely used for qualitative compound identification.

At RISE, we analyse a broad range of natural and synthetic polymeric and composite materials, including fibres, pulps, papers, barriers, coatings, and packaging. Bulk, surface, and layered structures can be examined separately. Our extensive reference database of material spectra serves as a valuable tool for accurate identification.

Using our µ-FTIR imaging spectroscopy system, we can analyse structures as small as 5 µm (transmission) and 1.25 µm (ATR).

We offer analysis of:

• Chemical composition
• Relative content
• Product defects
• Identification of impurities
• Homogeneity and distribution of components

Microplasic analysis

By definition, microplastics are insoluble plastic particles measuring between 1 µm and 1 mm, including subdivisions into narrower fractions, while “large microplastics” refer to particles sized between 1 mm and 5 mm.

Microplastic pollution poses risks to health and the environment. At RISE, we provide comprehensive analysis using µ-FTIR imaging spectroscopy, delivering statistical reports on particle count, identity, and size distribution. All procedures follow ISO 24187 (September 2023).

We analyse microplastics in samples such as:

• Water* (e.g., drinking water, sea water, river water, lake water, ice, snow, rain, pulp and paper process water)
• Recycled pulps, recycled papers, coated papers, printed paper, paper packaging
• Textiles   (i.e., microplastics from textile sources)

*non-toxic water, non-bio-hazardous water, non-radioactive water

It is important to build according to the regulations that exist today, but sometimes there can be problems anyway. We have a long experience of assessing both that the sound environment is satisfactory in new buildings, for example through our work with P-marking, and investigate why the sound environment is perceived as unsatisfactory in existing buildings. In homes, in different workplaces from office landscapes to hospitals, in schools and in other areas, we have investigated what problems the sound environment poses for the business and what the causes are. Sometimes we have been involved in the process and come up with measures and improvements. Sometimes we have had the role of third-party auditor, where we acted on the basis of RISE status as an independent institute, depending on the needs of the customer. To help us, we have all the resources required to run qualified acoustic assignments in the field.

Measurements in buildings

Report

The sound environment in offices, schools and in our homes affects both how we feel and how we perform. Furniture and interior design products optimized for good acoustics yield better indoor environments and thus better working conditions. We can measure and assess acoustic properties of entire indoor environments as well as of individual products

In our fully equipped acoustic laboratory, we provide independent testing and accredited measurements of products. We also make field measurements of acoustic parameters in real environments and perform listening tests to evaluate how different sounds are perceived. When we test products such as suspended ceilings, screens, baffles and furniture, we often measure sound absorption, but we are also accredited to measure, for example, screen damping, footfall noise et cetera.

Standards we are accredited for include sound absorption according to SS-EN ISO 354, SS-EN ISO 10534, SS-EN ISO 16487 and ISO 11654, screen attenuation according to SS-EN ISO 10053 , standards for sound properties of furniture SS-ISO 20189, etc.  We use the editions that are valid or specifically required for a certain certification.

We are also active in the development of new standards, such as the international standard ISO 22955 Acoustic quality of open office spaces, and where a representative from RISE participated as the appointed expert from Sweden in the work. Our mission in this context is to promote Swedish industry interests, and we welcome a dialogue if you have ideas for improvements of the standards. We can certify your products for different acoustic standards and markets. It can be anything from a complete CE marking to provide the needed information for marking products with TMF's Möbelfakta label

We measure according to accepted standards, which include ISO 354, ISO 10534, ISO 11654, ISO 10053, ISO 20189, SS 25269, ASTM E-1111 etc.

Test reports, and, where applicable, certifications.

We provide accredited calibration of laboratory sieves according to ISO 3310-1 (metal wire cloth sieves) and ISO 3310-2 (perforated metal plate sieves). The calibration is carried out in our accredited laboratory in Borås, Sweden.

The calibration illustrates whether your sieves reach the set requirements according to  ISO 3310-1 and ISO 3310-2 or not.

The calibration is carried out according to ISO 3310-1 and ISO 3310-2.

Calibration certificate according to method is obtained.

To order, please contact RISE in advance through the contact form. When ordering, please fill in the ordering form and enclose this to your order/shipment.

See general and special terms and conditions applying to projects and accredited assignments Terms and conditions | RISE.

Delivery time is ca 3 weeks from the arrival of the sieves to RISE sieve calibration laboratory, Borås. Delivery time can only be guaranteed after agreed order/date of calibration. If the calibration service is ordered well in advance, the delivery time might be significantly shortened.

If possible, the sieves are cleaned before they are sent in for calibration (cleaning costs will be added if necessary). Make sure the sieves are well packed and protected before shipping. Please fill in the ordering form for easier/more correct management of the calibration commission.

Paper surface roughness plays a crucial role for printability and visual appearance. Several types of instruments are available topography measurements of paper surfaces in different degrees of detail. The FRT MicroProf instrument has the advantage of combining high resolution with a large scanning area. Many other materials can be analyzed as well

Surface defects can be quantified in a very detailed way

Surface classification of different samples can be made.

The instrument uses a fast non-contacting high-resolution sensor, based on confocal microscopy with chromatic aberration. When white light passes through a lens with chromatic aberration, different colors focus at different distances. The color composition of the reflected light is analyzed and translated into a height position.

A surface is analyzed by moving the sample holder (X-Y vacuum table), while the sensor is in a fixed position. The utilization of a fixed sensor head means an advantage in speed, when compared to instruments using for example a z-scanning confocal focus sensor.

The x/y resolution is from 2x2 µm and the z-resolution 3 nm.

The height data is evaluated to generate height maps, profiles and pictures as well as common surface parameters, e.g. Ra, Rs etc., depending on the customer's needs.

A useful way of evaluating roughness is to band-pass filter the height map using the image analysis technique Fast Fourier transform (FFT) to divide the height variation in spatial size classes to get roughness components in different wavelength bands.
