Dialkyl diketene dimers (AKD) are used in the paper industry to add hydrophobicity to paper. Unbound AKD can get hydrolyzed to dialkylketones, which can potentially migrate to fatty foods from food packaging.

Dialkylketones have limitations according to BfR XXXVI.

We offer analysis of dialkylketones from AKD in solvent extract according to SS-EN 15519.

We also offer analysis of dialkylketones from AKD in coffee and in coffee with milk. For analysis in other type of foods, send request.

The results will be compiled in an analysis report.

Measuring drugs or doping substances in wastewater makes it possible to estimate the amount of abuse substances over a certain period of time. It provides an overview of the abuse and trends in an area or workplace.

Measurements of substances are carried out either upstream, for example in the sewage of workplaces and schools, or downstream in treatment plants, which can then provide an overview of usage in a municipality. Compared to, for example, interview questions and random samples at workplaces, these measurements offer a more objective assessment of entire populations and serve as a good replacement or complement to other interventions at a workplace or in an area.

Wastewater analysis of drugs and doping is a cost-effective method for assessing drug use on a large scale. It can also be used to identify differences between different areas in a city or even measure differences between departments and buildings within the same workplace.

We measure the presence of drugs and/or doping agents in water samples using mass spectrometry (LC-MS/MS). In the drug panel, we analyze approximately 10 commonly occurring substances, and in the doping panel, about 16 different agents.

Our analysis methods have been validated through an intercalibration study within the SCORE research network, which is responsible for organizing annual surveys of drug use in Europe through analyses of municipal wastewater.

If you are unable to carry out the sampling yourselves, we are happy to assist with that service.

We compile the results of the analyses in a report where we usually indicate levels per 1,000 inhabitants & 24 hours.

In addition to the analysis of controlled substances we can offer assistance with interpretation (consultation), presentation, calculations based on prescription of substances, and help you compile results into larger reports.

Delivery of the report approximately 4 weeks from the time we received the samples.

The samples are taken in plastic bottles and frozen as soon as possible after sampling. The samples are shipped frozen to RISE.

At RISE we are developing and implementing state of the art measurement and diagnostic techniques with tunable diode lasers to monitor and enhance the performance of thermochemical conversion processes. The techniques enable real-time, accurate measurements of difficult-to-quantify entities in hot and enclosed environments.

Advanced optical measurement techniques, specifically Tunable Diode Laser Absorption Spectroscopy (TDLAS) have developed and matured in recent years and can offer new and exciting alternatives for monitoring industrial processes.  The technology relies on the fact that chemical species of interest will absorb infrared light at certain known frequencies, while not absorbing any light at "off" frequencies, a simple concept that allows for robust measurements in difficult environments.  Residence time of TDLAS measurements is determined by the scanning rate of wavelength around the chemical species spectroscopic feature ( on and off the peak). Typically we work with 1-10 ms scanning intervals.  Equipment for TDLAS is inexpensive compared to competing technologies such as FTIR.

RISE at the forefront

RISE is focused on both developing the TDLAS technology for new uses as well as implementing TDLAS technologies within industry.  Current research focuses on using TDLAS to adjust fuel feedstock flows in real time to achieve better combustion efficiency.  Implementations at industry are focused on measurements of temperature, soot,   NO, CO₂, H₂O, CO, C₂H₂, CH₄ as well as biomass flow and moisture content.

• Following fuel conversion during biomass gasification using Tunable Diode Laser Absorption Spectroscopy diagnostics
• Simultaneous diagnostics of fuel moisture content and equivalence ratio during combustion of liquid and solid fuels
• Laser-based detection of methane and soot during entrained-flow biomass gasification
• Measuring NO and temperature in plasma   preheated air using UV absorption spectroscopy

Our expert researchers and engineers are enthusiastic about this technology and are available to aid in a successful implementation or research initiative.  

TDLAS implementations offer an extremely robust method for capturing data in difficult environments, using non-invasive light beams for the measurements.  Difficult environments such as sooty or gasified gas streams are no problem for TDLAS techniques, because the baseline measurement factors out the additional absorption.  Additionally, the use of lasers emitting exact frequencies means that calibration is never required and results are repeatable.

Normally, two optical ports (sight glasses) are needed on opposite sides of the furnace or reactor vessel, in order to emit and detect the laser beam.  

RISE can supply laser measurement equipment as well as software for signal interpretation.  We offer the expertise needed for implementation, support, and development. 

Certain chemical compounds are mutagenic; they can alter DNA and lead to severe diseases like cancer. When working with novel substances, it is essential to assess their mutagenic potential. At RISE, we offer a simplified bacterial reverse mutation test (Ames test), which is a cost-effective initial screening assay to detect mutagenic compounds.

The purpose of the Ames test is to identify whether a substance has mutagenic potential, i.e. the ability to cause genetic changes. The test is used as a first step in the risk assessment of chemical compounds. By using specific bacterial strains, it is possible to quickly and cost-effectively detect the ability of substances to induce mutations.

The bacterial reverse mutation test uses strains of Salmonella typhimurium and/or Escherichia coli to determine whether a compound is mutagenic. The strains carry specific point mutations that prevent them from synthetising an essential amino acid. As a result, they can only grow if that amino acid is present in the growth medium. The test detects reverse mutations that restore the bacteria’s ability to synthetise the amino acid. The revertant bacteria are detected by their ability to grow in medium lacking that amino acid.

At RISE, we offer a simplified version of the method described in the OECD Test Guideline No. 471 (Bacterial Reverse Mutation Test) of the OECD Guidelines for the Testing of Chemicals. This version uses two S. typhimurium strains: TA98, which carries a frameshift mutation, and TA100, which carries a base-pair substitution. Both mutations are in the histidine operon, making the strains unable to produce histidine.

The test involves exposing the strains to six concentrations of the test compound, both with and without a metabolic activator. The bacteria are then incubated in a histidine-free medium. A dose-dependent increase in the number of revertant colonies indicates that the compound is mutagenic under the test conditions.

The laboratory at RISE is certified by ISTA and is one of the most well equipped and advanced laboratories in all of Scandinavia for testing packaging. We carry out tests according to international standards, to ensure the performance of the packaging.

The test is performed to evaluate how pressure, due to high altitude, affects products or packaging during, for example, transportation. This can be done both during design development or to verify a finished design.

Vacuum testing can also be used to detect leaks in packaging, such as vials, which can be an effect of high altitude.

The test is performed in a vacuum chamber of dimension 1250 x 900 x 1300 mm and with a working range between atmospheric pressure, 1000 mbar, and down to 70 mbar.

595 mbar is commonly used when the test method is included in transport tests, which corresponds to the pressure at an altitude of 4267 meters.

Report received after completion of testing.

The delivery time is approximately 2 - 4 weeks depending on the selected test method and number of packages to be tested.

Flexible sealants and joint sealants play a crucial role in building and construction projects. They ensure that joints are tight, protect against moisture ingress and maintain the durability of the building over time. The consequences of using a joint sealant with the wrong properties can be enormously costly.

The importance of testing flexible sealants and joint compounds

By carrying out standardized tests, the performance of the sealant can be assessed and it can be ensured that it can withstand stresses such as temperature variations, mechanical loads and environmental influences. 

Without tests, there is a risk of cracking, weakened adhesion and, in the worst case, leakage that can cause damage to the building. Common test methods include creep and elasticity tests as well as determination of adhesion and durability over time. 

By following international standards, such as ISO 11600, it can be ensured that the sealant meets both functional and aesthetic requirements.

With a wide range of equipment and several years of expertise, we can perform a variety of testing methods, all depending on the customer's needs, both standardized and specially developed methods for damage investigations.

When assessing the chemical properties materials, information from a single location is rarely enough to understand a process. In Kista, RISE has a state-of-the-art equipment for performing spatially resolved vibrational spectroscopy on the macro-, micro-, and nanoscale along with cells for tracking time-resolved surface reactions.

Materials and their surfaces exhibit behaviors and characteristics at multiple scales, with variations dependent on both time and location along the material. Corrosion products on a metal surface can form homogeneously across an entire surface or spread from initiation points. Degradation reactions in protective coatings can initiate at the surface and slowly progress into the coating, or failure can occur underneath the coating without any discernible changes at the surface. These are examples of complex behaviors that can easily be misunderstood or completely missed unless the correct type of analysis is performed. RISEs platform for multiscale surface and interface analysis aims to enable customers and partners to gain a deeper understanding of complex processes, and suggestions of how to use this knowledge in their day to day business.

Chemical analysis can be performed at different spatial scales:

• Without spatial resolution. These methods include Attenuated total reflection (ATR), transmission (both solid and liquid samples), photoacoustic spectroscopy (PAS), and reflection including infrared reflection absorption spectroscopy (IRRAS). In addition to high signal-to-noise ratio these methods can also be combined with time resolved analysis and follow reactions and in situ.
• At the microscale. The FTIR microscope in Kista can perform hyperspectral imaging collecting up to 4096 spectra in parallel at a spatial resolution of up to a few µm.
• At the nanoscale. With the possibility of performing IR spectroscopy or chemical mapping with a spatial resolution of just 10 nm.

In addition to infrared spectroscopy, complementary Scanning Kelvin probe (SKPFM) and topographical analysis is also available.

The instruments that are part of the platform are listed below:

• Vertex 70 spectrometer with a wide array of accessories, and cells.
• Hyperion 3000 with both MCT and spatially resolved FPA detectors
• NanoIR3, including AFM-IR and topographical measurements with humidity control, and SKPFM

Deliverables are customized to the need of the customer and can include reports, oral presentations, or raw data.
