Analytical Methods

Method DevelopmentThe SafeBridge laboratory has developed or modified industrial hygiene sampling and analytical methods to help our clients meet their workplace air monitoring requirements. Our methods achieve high sensitivity and high recovery rate through the proper choice of filter media and extracting procedures as well as the optimization of air and surface sampling parameters.

The methods are validated with respect to analytical detection limits, precision and accuracy. Data on the stability of compounds relative to airflow volume and storage conditions and recovery off of surfaces are contained in these methods.

Our Capabilities

  • Method Development and Sample Analysis - Routinely develops methods and analyzes industrial hygiene samples for biologically active pharmaceuticals such as steroids hormones, peptide hormones, antibody drug conjugates (ADCs) and cytotoxic compounds.
  • Analysis of Potent Compound Surrogate Materials - Analyzes samples for verification of containment systems. We typically use naproxen sodium, mannitol and lactose as surrogates with a limit of detection as low as 50 pg of material on a filter. Insulin, with a limit of detection of 200 pg per filter, may also be used as a surrogate when ultra sensitivity is required, or as a surrogate for high molecular weight component.
  • Cleaning Method Development - Conducts assessments of cleaning methodologies that are employed for both occupational settings and for QC/QA cleaning validation purposes.
  • Permeability Studies - Conducts permeability studies of potent pharmaceutical compounds through gloves and other protective equipment materials.


AIHA-LAP Accreditation

SafeBridge Laboratory is accredited by the American Industrial Hygiene Association Laboratory Accreditation Programs (AIHA-LAP, LLC) for the analysis of active pharmaceutical ingredients. AIHA-accreditation means the following:
