Analytical Testing and Quality Control services in detail
Method development, validation, and transfers
Our team of experts can develop and validate appropriate analytical methods, to assess content, purity, identity, and compliance with pharmacopeial requirements and methods. This includes physico-chemical testing and microbiological testing.
Our team can also implement and transfer analytical methods from any 3rd party.
Our analytical services panel includes a vast range of methods and equipment, allowing us to perform pharmaceutical testing on various therapeutic modalities, from small molecules to biologics and others, ensuring adherence to rigorous quality and biosafety level standards.

QC (Quality Control), Release & Stability Testing
We perform release and stability services, either in combination with Development or Drug Product Manufacturing, or as a stand-alone service. We can perform QC release testing according to cGMP for clinical and commercial Drug Products, including physico-chemical and microbiological testing, including identity, content, purity, and pharmacopeial and microbiological endpoints.
Stability testing is required to determine an appropriate shelf life and evaluate product stability. Our qualified walk-in stability chambers include refrigerated (2-8°C), 25°C/60% r.h, 30°C/65% r.h., 40°C/75% r.h. and we can also evaluate stability in a frozen state (-20°C, -40°C, <70°C). Additionally, we can perform Photostability testing (according to ICH).
For development purposes we would also typically recommend evaluating interfacial stresses.

Characterization and Comparability
We at ten23 health can also support you in characterizing pharmaceutical products of therapeutic modalities, for example comparing any changes and product versions, may it be due to different processing, before/after site transfers, or any formulation, packaging, or device changes, etc. Such comparability assessments can also help compare molecules to their physiological counterparts or any other relevant reference products.

Special Analytics
We also provide special analytical services as follows:
- Particle Characterization: we can measure (quantify/quality) particles from submicron, to subvisible (micrometer) to visible sizes, using a range of technologies including light obscuration (employing different systems), microscopy (following PhEur 2.9.19), and flow imaging. For visible particle testing, we follow pharmacopeial requirements (PhEur 2.9.20). Particle identification uses for example microscopy and spectroscopy. Additional technologies are available in collaboration such as AUC.
- Container Closure Integrity (CCI) Testing: we can assess container closure integrity and typically recommend deterministic CCI testing using Helium leakage. We can perform these evaluations with various container options including polymer containers. We can also support other CCI assessments.
- Device functionality testing: our assessments can include functionality testing for syringes, cartridges, or other functional containers. This would include break-loose and glide-force testing (BlGF).
