Accurate, reliable, cost-effective compliant analytical testing and method development services to support pharmaceutical products along every step from early-stage development to commercial manufacturing.

Proven Expertise and Modern Technology

Analytical support of pharmaceutical products demands knowledgeable experts coupled with modern analytical instrumentation. CAL is privileged to have exceptionally well trained and experienced pharmaceutical professional chemists and microbiologists. This in-house expertise allows for rapid method development in a logical and rationally planned approach that yields robust accurate and precise methods.

Each year the analytical instruments improve in terms of design and limits of detection and quantification. CAL’s robust investment program into modern technologies and analytical instrumentation assures not only a broad service profile but a refinement of existing technologies to assure accuracy and precision of the assays we execute.

Our expert teams coupled with our investments in analytical instrumentation are predicated on the execution of our laboratory services in a fully GMP compliant manner. CAL views the relationship with our clients as a true partnership.

Analytical Methods: Development, Transfer and Validation

The subject matter experts at CAL thrive when challenged to solve difficult analytical challenges. For over 35 years, we have played an integral role in pharmaceutical product analysis by creating new reliable, robust, fit-for-purpose analytical methods or improving existing methods that can reduce overall product analysis time and bring cost efficiency. Our responsive, and flexible approach applies to method development, transfer, and validation whether it is related to raw materials, in-process products, or finished products. The responsive and collaborative approach is especially beneficial when working with rare, highly expensive impurities when several parties outside of the sponsoring client are involved.

Method parameters (based on ICH guidelines):

  • Specificity
  • Limits of detection and quantification
  • Linearity
  • Accuracy
  • Precision
  • Standard and Solution stability
  • Degradation studies (acid/base/pH/heat and light)

We also validate methods developed by other laboratories and can perform gap analysis of previously validated methods to ensure they meet current guidelines. Our rapid method development expertise can help to expedite the most appropriate method for your product.

Thermogravimetric Analysis (TGA)

TOC analysis machine

Thermogravimetric Analysis (TGA) is available for quantification of impurities in raw materials and active pharmaceutical ingredients to characterize and verify materials for QA/QC material specification requirements.

Impurity testing is typically a costly but necessary activity as regulations on pharmaceuticals have been lowering limits for impurities over the past several years. In so doing, this has necessitated detection methods to become more sensitive and selective resulting higher testing costs for pharmaceutical companies.

TGA provides a significantly more cost-effective approach as much smaller sample sizes are required to produce highly accurate and reproducible results.

We have developed in-house methods, as well follow compendial or client-provided methods.  We also have deep expertise in developing new methods when no current method exists.
