Chemical changes
Assessing the chemical integrity of a biopharmaceutical compound
All biopharmaceutical compounds – being it peptides, proteins, vaccines, or virus-like particles – are sensitive towards chemical degradation. Examples are deamidation, hydrolysis, oxidation, photo-degradation, disulfide-scrambling, and others. Chemical degradation can lead to aggregation, charge variants and/or structural changes of the drug substance and eventually impair the effectivity or safety of the therapy.
Developing a stable drug product and finding suitable storage conditions
Our analytical scientists develop and apply phase-appropriate and orthogonal analytical methods to identify the criticality of different degradation pathways under accelerated stress conditions or during long-term storage. The so obtained knowledge enables the data-driven development of a robust and stable drug product formulation and the definition of suitable storage conditions.

Quality & biosafety level of this service
We provide all our services with the highest quality standards. Each project is carried out by experienced scientists and every report or data presentation is comprehensively checked by a scientific reviewer. We offer this service with the following quality and biosafety level:
From generic to custom analytical methods and beyond
We offer a large selection of generic analytical methods for many common applications or develop custom methods specific for your needs. Our expert scientists also perform a method feasibility to assess, which technique is most suitable for your request. We offer the following options:
Methods ready to use
Our expert scientists have established generic analytical methods for many common applications. This guarantees a quick turnaround for sample testing and reduces the need for method adjustments to a minimum.
We suggest generic methods for your sample based on our many years of experience with similar products and analytical questions. If you reach a development stage, where fully developed and documented methods are required, we can build upon our expertise in customizing and optimizing any analytical method.
This is available for a selection of analytical techniques.
Method development
During method development, we tailor sample preparation, method settings, and data analysis to the needs of your project and sample.
For this purpose, we include a representative sample and, where available, suitable reference standards and stressed/degraded materials. This way, our analytical scientists can design a method that is highly suitable for your needs, stability indicating, as well as robust and repeatable. Upon request, we compile a detailed method description for your records.
This can be applied to all our techniques (R&D and GMP). Read more.
Method qualification
A method qualification is the initial assessment of the performance of an analytical procedure to show that it is suitable for the intended purpose.
During method qualification, our analytical scientists perform documented testing to establish and assess acceptance criteria in several performance characteristics. These may include repeatability, linearity, intermediate precision, robustness and more. We compile a qualification plan and a qualification report including all relevant data.
This can be applied to all our techniques (R&D and GMP). Read more.
Method validation
A method validation is the confirmation under highly controlled conditions that the performance of an analytical procedure is suitable for the intended purpose.
During method validation, our analytical scientists perform a documented testing, which demonstrates that the analytical procedure consistently produces a result that meets pre-determined acceptance criteria. We compile a validation plan and a validation report including all relevant data.
This can only be applied to our techniques under GMP. Read more.
