What is Process Analytical Technology?

Process Analytical Technology (PAT) is a regulatory framework initiated by the United States Food and Drug Administration (FDA) that encourages pharmaceutical manufacturers to improve the process of pharmaceutical development, manufacturing, and quality control.

PAT aims to improve process efficiency and process control by defining Critical Process Parameters (CPP) and monitoring these CPPs to stay within a defined limit, either in-line or on-line to maintain a product’s Critical Quality Attributes (CQA). Monitoring CPPs with process mass spectrometry gas analysis reduces over-processing, pinpoints contaminants and increase product consistency.

Fermentation
Fermentation process control in real time with fast, precise gas analysis

Analysis of respiratory gases is an ideal way of fermentation monitoring. It’s non-invasive and provides invaluable information on the physiological state of the culture, including growth kinetics and substrate consumption. It also helps determine the optimum point to halt the process for maximum yield. Many fermentations are characterized by small changes in oxygen and carbon dioxide concentrations. The speed of MS makes it ideal for fermentation process control, but speed must not be at the expense of precision. It is equally important that precise data is acquired; otherwise, small changes in concentration will be lost.

Over 30 years of industrial experience have shown that magnetic sector analyzers offer the best performance for fermentation off-gas analysis. Key advantages include improved precision, accuracy, long intervals between calibration, and resistance to contamination. Typically, analytical precision is between 2 and 10 times better than a quadrupole mass spectrometer.

Product Drying
Use magnetic sector mass spectrometry to control the solvent drying process with fast, precise, quantitative data

A key stage in many pharmaceutical processes is the complete or partial removal of a solvent or solvents from a product or intermediate. This solvent recovery process can occur in a variety of process vessels, including vacuum dryers, tray dryers and rotary dryers.

In the past, the success of the solvent drying process was simply measured at the end by taking a sample for laboratory analysis and the amount of residual solvent was defined by the Loss on Drying (LOD). If the sample failed the LOD test for one or more of the solvents, then the drying process had to be restarted. If the drying took place under vacuum, this provided additional complications in terms of both sampling the active pharmaceutical ingredient (API) and re-starting the dryer.

Mass spectrometers have been used to monitor solvent levels in the headspace above the API during drying processes but they have typically only produced qualitative or semi-quantitative data. If the MS is to be used as part of a PAT solvent drying process control project, it must produce accurate, reliable quantitative data, even for multi-dryer, multi-solvent systems. 

Featured product
Prima PRO Process Mass Spectrometer

Thermo Scientific Prima PRO VP can monitor up to 10 dryers, with a unique inlet that can switch between dryers at widely differing pressures and concentrations, and still provide reliable, stable solvent concentration data. Features include:

  • Magnetic sector MS, providing stable fragmentation patterns and resistance to contamination.
  • 10-port Variable Pressure sampling inlet, able to handle process pressures between 1000 mBar and 0.3 mBar.
  • Samples from headspace above the product, measuring the bulk API in the dryer and avoiding problems with grab samples caused by lack of homogeneity.
  • Easy, simple calibration with either gases or liquids ensures accurate quantitative data.
  • 21 CFR Part 11 compliant GasWorks software.
Thermo Scientific Gas Analysis Mass Spectrometers

Off-Gas Analysis:

In mammalian cell fermentations, the feed gas composition is a frequently changing mixture of several compounds. The feed gas concentration also ranges vary dramatically. The implementation of real-time, off-gas analysis using Process Mass Spectrometry in mammalian cell culture can help identify process deviations during bioreactor runs and evaluate batch to batch variation, within predefined specifications, for robust manufacturing.

Metabolite Monitoring:

In biopharmaceutical production, cells require a feeding cycle of glucose to enable cell reproduction. The Thermo Scientific Ramina Process Analyzer leverages compact and simplified hardware along with data science tools to model the glucose content of a bioprocess and tell you exactly when to add more glucose to ensure cell production at a precise rate.
