TAB APCP ver 3.0 states that testing on corrosion to metals shall follow the UN Test C.1 AND it must be guaranteed that the content of the active substance throughout the test is kept stable, thus the composition should be checked/analysed throughout the test or at least at the end of the test.
If you are affected, contact us to discuss an individual strategy for testing your biocidal product.

The deadline for applying for product authorization for the active substance DDAC in biocidal products of PT 1 and 2 is 01 February 2024. Good to know that LAUS has already experience with the analytical determination of quaternary ammonium compounds like DDAC. Contact us for more information.
Due to the geopolitical situation there are numerous bottlenecks in the supply chains of many companies. If you have identified a new, alternative supplier for your chemical, who has not imported into the EU yet, you need to make sure that you act in compliance with the EU chemicals regulation, REACH. You will need a Sameness analysis to proof the substance identity of the chemical to include your supplier in the respective REACH dossier. LAUS has extensive experience with Sameness analyses and could deliver reports within a few weeks’ time.
The rate and extent to which metals and sparingly soluble metal compounds can produce soluble available ionic and other metal-bearing species in aqueous media is determined in the Transformation/Dissolution study under a set of standard laboratory conditions. LAUS has many years of experience with the performance of this study according to OECD GD 29 under GLP. Contact us for more information!
Clients who need analyses or experimental endpoints of a gaseous substance often have a problem with sample shipment. LAUS now has a „Travel Gas Cylinder”. This container can be shipped to pick-up your sample and has two major advantages:
It has a good size for a reasonable amount of sample.
It is equipped with the exact valve we can use in our system.
Talk to us if you are planning to test a gas, and we could discuss the requirements!
The Fourier Transform Infrared Spectroscopy (FTIR) spectrum of a polymer is like a fingerprint and allows its identification.
The ATR (Attenuated total reflection) method enables us to analyse all kinds of polymers (solid, powder, films, granules, soluble, etc.) directly or after grinding. The FTIR spectrum collected in the wavenumber range 500cm-1-4000cm-1 will be compared with our polymer data base containing more than 10.000 spectra. The best matches are being reported.
Why can the determination of the Particle Size Distribution (PSD) be challenging?
The PSD is required for a number of regulatory purposes:
granulometry for the REACH dossier of solid substances (OECD 110)
REACH substance identity profile (sameness) for Nanomaterials
the definition of nanoforms
analytical determination of nano materials in genotoxicity or ecotoxicological studies
The smaller the particles are, the more elaborate the techniques have to be. LAUS has equipped a new lab with state-of-the-art technology and trained a highly qualified study director. We have developed a deeper understanding on how to approach the different substance types (e. g. nanomaterials) and how to receive comprehensive results. Sometimes complementary techniques like SEM/TEM, XRD with Rietveld or BET are required to describe a substance in its entity.
For Plastic Food Contact Materials EFSA requires genotoxicity testing including a minimum of two in vitro studies:
i) A bacterial reverse mutation test
ii) An in vitro mammalian cell micronucleus test
In a first step the specific migration limits (SML) expressed in mg of substance per kg of food (mg/kg) needs to be determined for the packaging material. If the exposure through migration is low, this limited data set might be sufficient. If the exposure is higher, a strategy with more toxicological information will be required.
A NRES is a new registrant of a substance that was previously registered under EU REACH before 1 January 2021 by any legal entity.
First step in the process is to submit an Article 26 inquiry according to UK REACH. When the NRES status has been confirmed, 2, 4 or 6 years plus 300 days from the end of the transition period (i.e. from 31 December 2020) remain for the submission of the full information requirements.
If you are a non-GB based manufacturer or formulator your OR must submit analytical data generated from a sample manufactured by you or your non-GB based manufacturer for an Article 26 inquiry under UK REACH:
An inquiry dossier should contain information:
- about the potential registrant
- about the identity of the inquired substance
- where the potential registrant would need to carry out new studies, including those involving vertebrate animals.
LAUS can support you with both, the OR service and the generation of the analytical data for the substance identity.
