Analytical Services

A critical component of any regulatory submission of a NDA or ANDA is the analytical quality package. At Coldstream, our skilled analytical team will develop and validate analytical methods to support the formulation process release of finished product, and ICH stability testing.

The Coldstream analytical laboratories contain state-of-the-art instrumentation, such as HPLC and GC, along with cGMP stability chambers covering -20°C, 2-8°C, 25°C/60%RH, and 40°C/75%RH. Our laboratories are also equipped with a special cytotoxic and potent handling area.

Our highly experienced staff have expertise within all aspects of pharmaceutical analytical sciences. The analytical team collaborates closely with the other Coldstream divisions ensuring success of the project with a goal of exceeding customer expectations.

Method Development, Qualification, and Validation

At Coldstream, we support clients in developing and validating analytical methods in all stages of drug development, from pre-clinical studies through commercial manufacturing. Our analytical team develops robust methods that are designed according to the phase of drug development. Additionally, our team will transfer and validate existing methods to confirm that analytical procedures are suitable for their intended use.

Stability Studies

In order to ensure the safety and efficacy of your drug product, Coldstream currently offers stability programs with chambers covering -20°C, 2-8°C, 25°C/60%RH, and 40°C/75%RH, as well as an R&D photostability chamber. Our wide variety of testing services, according to the International Conference on Harmonization (ICH) guidelines, will equip you with the data that you need for your filing.
