Analytical Chemistry and Instrumentation

The chemical analysis is a key element in the successful registration or approval of chemicals, biocides, pesticides, and pharmaceutical products. Our experts apply methods specifically tailored to your substance or product, designed to meet the relevant regulatory requirements. Our service portfolio includes:

Analytical Methods

• Development and Transfer of methods specifically for individual test items and matrices
• Validation according to SANCO 3030/99 or SANTE/2020/12830
• Revalidation or ILV Studies (Independent Laboratory Validation) for the identification and quantification of active substances in Plant Protection Products according to SANCO/3030/99 rev. 4

Applications

• Verification of test item concentration (dose) within ecotoxicological, toxicological and physico-chemical studies
• Determination of content of active ingredients in formulations, also in connection with storage stability
• 5-batch analysis
• Impurities
• Residue studies of pesticide products in various matrices
• Sameness studies according REACH

The regulatory requirements for analytical methods are constantly increasing, while technological capabilities continue to advance. Our extensive range of instruments is state-of-the-art and enables measurements down to the technically achievable limits of detection.

Analytical instrumentation

• High Performance Liquid Chromatography (HPLC/UPLC/LC)
  Detection: UV, DAD, FLD, RI, ELSD, MS, MS/MS (Triple Quad, Waters, Sciex)
• Gas Chromatography
  Detection: FID, MS, MS/MS, HS Headspace
• Induced Coupled Plasma - Optical Emission Spectroscopy (ICP-OES) or - Mass Spectrometry (MS)
• Ion Chromatography (IC) for anions
• Photometry UV-VIS
• Titrations: Automatic titrator, manual burettes, Karl Fischer
• TOC: Total Organic Carbon
• SEC: Size Exclusion Chromatography

Other Analyses

• FTIR with ATR
• SEC with RI
• DLS Dynamic Light Scattering
• Laser Diffraction: solid and gas
• Tyndall Effect Measurement (Concentration of silica particles in water)

This combination of expertise and advanced technology enables us to analytically determine all types of substances, including those that are particularly challenging to test.

Test items

• Organic / inorganic
• mono-constituents / multi-constituents / reaction mass / UVCBs (unknown or variable composition, complex reaction products or biological materials) / mixtures / pigments and dyes
• difficult to test: poor solubility, unstable, adsorptive, volatile, toxic

For example, for the digestion of poorly soluble substances, we use a state-of-the-art microwave system.

At LAUS, our highly qualified and experienced study directors combine cutting-edge technology with scientific expertise to deliver top-quality analytical services for your products—ensuring precision and reliability you can trust.
