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!

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.

Results could be used for

• Safety Data Sheets
• REACH Substance Identification

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.

If you want to get access to data sharing under chemical legislation around the world, you need a Substance Identity (also known as “Sameness”) of your substance.

- EU REACH

- China REACH

- Korea: AREC („Act on the Registration and Evaluation of Chemical Substances“), K-REACH

- Türkiye: KKDIK, Türkiye REACH

- United Kingdom: UK REACH

Our experts will gladly choose the required analyses for your substance. Ask us for a quotation.

With Laser Diffraction and Dynamic Light Scattering techniques LAUS is now able to perform measurements

• from 0.3 nm to 3,500 µm particle size
• in wet dispersion (0.3 nm - 850 µm)
• in dry dispersion (100 nm - 3500 µm)
• for solids, suspensions and aerosols

We work according to current guidance

• OECD 110
• ISO 22412 Particle size analysis — Dynamic light scattering (DLS)
• ISO 13320:2020 Particle size analysis - Laser diffraction methods
• Many ASTM and U.S. Pharmacopeia methods

Testing is offered with and without GLP and could be used for R&D as well as for regulatory purposes.

First step of any new registration under UK REACH is to submit an Article 26 inquiry. There are two more szenarios where you should submit an Article 26 inquiry to HSE:

- You have completed the DUIN and would like to start with the data sharing process.

- DUIN is not possible since you do not fulfill prerequisites.

After the inquiry you will receive your inquiry number and become part of a substance group - a group of potential co-registrants of the same substance (formerly known as SIEF under EU REACH). This will enable you to engage in the data sharing process for a successful registration within the applicable timeframe. Questions? Click here or contact us!
