Modern biopharmaceutical drugs, such as monoclonal antibodies (mAbs) and antibody drug conjugates (ADCs), are tremendously complex molecules manufactured inside living cells. Characterizing and monitoring these compounds in chemistry, manufacturing and controls (CMC), and quality control environments can present a significant challenge, but the use of high resolution accurate mass (HRAM) mass spectrometry offers a powerful way of overcoming these challenges.
The additional dimension of separation combined with the sensitivity and specificity of Orbitrap MS yields deeper product knowledge than a combined battery of conventional characterization tests, eliminating a large number of traditional lot release testing.
By directly measuring critical quality attributes at the individual residue level, understanding how changes in process or production affect a drug product becomes part of a "quality by design" approach. Together, the results provided by HRAM MS enable safer and more potent drugs to be manufactured, delivering a truly powerful research-to-routine workflow.
The adoption of mass spectrometry (MS) in quality control workflows is discussed in this Chemical & Engineering News article. MS experts talk about using mass spectrometry in pilot plants to replace some of the more traditional quality control assays. MS allows the detection of slight changes in biotherapeutics due to its increased sensitivity and specificity: “…the only instrument able to consistently detect these new peaks is the Orbitrap…”

To adequately cover the numerous different critical quality attributes required during QC analysis, several different analytical strategies are typically performed. Many of these analyses are time intensive and only serve to provide one piece of information.
Multi-attribute method (MAM) analysis (via peptide mapping) serves to provide significant amounts of information for biotherapeutic drugs, both reducing the number of analyses and different experiments required to be performed whilst increasing the product quality profile.
