Release testing

Release testing / Batch release

We perform GMP-compliant release testing for raw materials, intermediates, and finished pharmaceutical products and support batch release. This includes testing for assay (content), purity, drug release (dissolution), identity, and physicochemical parameters using modern analytical techniques such as HPLC, UHPLC, gas chromatography (headspace), and IR and UV/Vis spectroscopy.
Climate storage

Climate storage

For stability studies, we offer qualified climatic storage under controlled conditions in accordance with ICH guidelines. This forms the basis for reliable stability testing and the assessment of pharmaceutical product safety.
Method development/validation

Method development/validation

We develop individual and tailored analytical methods for robust routine operation. This includes method development as well as method validation in accordance with ICH guidelines, for example for assay (content), purity, or drug release (dissolution), using modern techniques such as HPLC, UHPLC, GC (headspace), and IR and UV/Vis spectroscopy.
Consulting

Consulting

As an experienced GMP partner, we support you with scientific and regulatory questions related to pharmaceutical analytics, stability testing, validation, and quality management.
Stability testing

Stability testing

From planning to final documentation: we are specialists in conducting stability studies of active pharmaceutical ingredients, finished drugs, medical devices, and cosmetics—including photostability, stress testing, in‑use stability, on‑going stability, and transport stability.

In doing so, we develop suitable analytical methods for the determination of assay (content) and purity, taking into account the formation of degradation products.

Highly active substances

Highly active substances

The analysis of highly potent substances such as cytotoxic drugs requires special safety measures and expertise. HHAC provides specially equipped laboratory areas as well as many years of experience in handling CMR substances.
Dissolution testing

Dissolution testing

We have extensive experience in the development, validation, and execution of dissolution tests to determine the release of active ingredients from various solid dosage forms such as tablets and capsules, as well as, for example, drug-containing transdermal patches.
Narcotics

Narcotics

In the field of narcotics, we offer specialized analytical testing and stability studies in full compliance with all regulatory requirements. Our services include the analysis of controlled substances as well as their storage in our climate chambers.

The special quality of our work

  • is based on our decades of work in pharmaceutical analysis and the experience we have gained in analyzing more than 400 active pharmaceutical ingredients in different dosage forms.

  • is demonstrated by our repertoire of analytical methods, which we have further developed and optimized over this period with the support of state-of-the-art laboratory technology.

  • is verified by comprehensive quality management, thus permanently guaranteeing the validity and precision of our results.
