Chemical and Physical Testing

A team of around thirty experts and laboratory personnel conducts extensive analytical services for customers from the pharmaceutical, medicinal products and cosmetics industry—always in compliance with the relevant regulations. Whether limit testing, purity tests, identification tests or the determination of content, melting point and osmolality—Labor LS offers its customers pharmacopoeial test methods, whose range is extensive in terms of both quality and quantity. This applies to tests according to the European Pharmacopoeia as well as the U.S. and Japanese pharmacopoeias (USP/NF and JP, respectively). Thanks to our many years of experience, we offer you the optimal efficiency in the handling of a large number of raw materials. We will be pleased to realise customer-specific requirements. The combination of a wide range of testing equipment and methods as well as our personnel's expertise guarantees the highest quality in both method validation and product testing.

Titrations

Titration is still an indispensable method of determining contents in chemical and physical analyses.

Titration is still an indispensable method of determining contents in chemical and physical (s.o.) analyses. The scope offered by Labor LS comprises classical hand titration, potentiometric titration and titrations with ion-selective electrodes as a part of content and purity analyses. In addition, we routinely carry out semi-micro determinations of water according to Karl Fischer.

Chromatography/Electrophoresis

High-performance liquid chromatography (HPLC) is used for the routine evaluation of raw materials, active pharmaceutical ingredients (APIs) and finished products.

High-performance liquid chromatography (HPLC) is used for the routine evaluation of raw materials, active pharmaceutical ingredients (APIs) and finished products. Next to the determination of content and purity according to pharmacopoeial methods, the focus of this methodology is on validations, method developments and method transfers specifically tailored to customers' products. The detection methods available to our customers are diode array (DAD), UV/Vis, refractive index (RI), pulsed amperometric and fluorescence detectors.

In the field of gas chromatography (GC), our service portfolio comprises tests for residual solvents, content and purity testing on raw materials, APIs and finished products. In addition, we offer comprehensive method developments and validations as well as the transfer of your methods to Labor LS. In the field of gas chromatography (GC), we use gas chromatographs with headspace and liquid injection.

The electrophoretic methods we offer in the context of development, validation and transfer include gel-based tests (agarose gel electrophoresis, SDS PAGE, isoelectric focusing) according to pharmacopoeial methods or to your own requirements.

Special Tests

In addition to the proven standard methods and procedures, we carry out a number of specific special tests.

In addition to the proven standard methods and procedures, we carry out a number of specific special tests, such as, for example, the quantitative determination of hyaluronic acid in liquid preparations, the activity determination of pancreas powder according to Ph Eur or the self-sealing test of containers according to Ph Eur 3.2.9 or USP <1207>, also known as container closure integrity test (CCIT), in defined low pressure / overpressure conditions with visual and UV-spectroscopic detection. In addition, we offer you comprehensive help with your cleaning validations.

Stability Storage

To test the stability of their products, we offer our customers a comprehensive package of services.

To test the stability of their products, we offer our customers a comprehensive package of services. We take care of the entire logistics, from collection (to be agreed separately) and storage (including or excluding analytics) up to the return and disposal of our customers' samples.
We create precise stability reports, test plans as well as test matrices and implement necessary storages even at short notice. As part of our comprehensive storage concepts, we guarantee the compliance with the highest security levels. Our climate cabinets and chambers, for example, are equipped with emergency generators and are continuously controlled by two monitoring systems.
We can offer the following climatic conditions for your stability tests:

  • -20 °C
  • -80 °C
  • 5 +/- 3 °C
  • 25 °C, 60 % relative humidity
  • 30 °C, 65 % relative humidity
  • 40 °C, 75 % relative humidity
  • 30 °C, 75 % relative humidity
  • 25 °C, 40 % relative humidity
  • 40 °C, 25 % relative humidity (starting end of 2015)
  • Special conditions are possible on request
