Summary of the webinar presented by Jan-Sebastiaan Uyttersprot


Even if you perform all the correct steps to validate a PAT method, it does not guarantee that the method will fulfill all the required criteria for success.


Analysis and troubleshooting of the underlying causes require an even more extensive PAT toolbox, as well as knowledge of data science. During the presentation, we will discuss the lessons learned and how to avoid similar difficulties in future projects.



Summary of the webinar presented by Davinia Brouckaert


Process Analytical Technology (PAT) can really change things if it is applied correctly. However, to take full advantage of PAT’s inherent benefits, you need to avoid certain difficulties during development of the method. In this webinar, Jan-Sebastiaan Uyttersprot of UCB Pharmaceuticals will explain how he approaches solving problems linked to the development of a PAT (Process Analytical Technology) method. In his quest for a PAT tool based on spectroscopy for real-time inspection of solid dosage forms, he looked into various technologies, from the laboratory through to production, seeking significant, information-rich data. During the presentation, he will discuss his own experience with Raman imaging, Raman transmission, NIR hyperspectral imaging and in-line spatially-resolved spectroscopy. He will also share the results of an industrial case study and compare the strengths and weaknesses of the technologies assessed.

Webinar on determination of protein aggregation by inline UV/Vis spectroscopy

At this webinar, find out about inline measurement of protein aggregation during biopharmaceutical production.

Protein aggregation

Protein aggregation is one of the most frequent causes of protein instability. Considered a critical quality attribute, this is an essential indicator in drug manufacture, whether upstream or downstream.

The development and production of pharmaceutical products such as monoclonal antibodies may be affected by protein aggregation. This phenomenon occurs in various production, storage and sample handling conditions. As well, this occurs in a large range of protein concentrations and formulations. The presence of aggregated forms of proteins is potentially problematic for these therapeutic products. It brings with it a risk of immunogenic and pharmacokinetic problems.

Consequently, it is essential to fully characterize, quantify and check the level of aggregates, their nature and their distribution. In the context of an effective analytical inspection strategy for biological and biopharmaceutical products, these checks need to be performed regularly.

Characterization and inspection

Although most aggregates form during the upstream operations, they may also occur during the downstream processing, for example when unsuitable conditions have been selected.

Successful bioproduction therefore requires thorough knowledge of the processes and a rigorous definition of their parameters.

This is why, during this webinar, we will be explaining how our Asuryan UV-Vis spectrometer can be used to acquire knowledge concerning the processes, whether during the R&D phases to reduce the time-to-market, or directly inline for early detection of protein aggregation to avoid reduced product yields.

Proteins, which are highly reactive molecules, are present in small quantities. They require a spectroscopy method suitable for such low concentrations. Thanks to its high sensitivity, UV spectroscopy is ideal for this type of measurement.

Furthermore, the adaptability of the Asuryan’s UV spectroscopic measuring system enables various different probes to be used. These cover the wide ranges of protein concentrations encountered in the different industries and during the various steps for their production.

An acknowledged player in spectroscopy and the owner of a large number of patents, INDATECH has designed Asuryan, an inline measuring and inspection solution ideal for therapeutic production:

  • Measurement sensitivity and accuracy at low concentrations,
  • Repeatability over time thanks to an internal reference measurement,
  • Simultaneous measurements at several points with different protein concentrations.

Webinar on the interest of online sugar color measurement (ICUMSA) in the food industry

In this webinar on sugar color measurement, you will learn how to measure it online to determine its quality and value.

Most food industries use sugar. Its purity depends on the final quality of the product, especially for beverages. The measurement of the color of sugar (in syrup or solid state) is the main criterion currently recognized. The international laboratory ICUMSA sets the standard for determining the amount of impurities.

Sugar industry is trying to increase the quality of their product to facilitate export and value. Especially true for some countries like Thailand or Brazil.

That is the reason why in-line sugar color measurement is becoming particularly critical to reduce reprocessing costs and gain efficiency. In order to meet this demand, INDATECH has developed an innovative solution capable of working on large ranges. Moreover, its solution meets the needs of both the sugar and the beverage industry.

This webinar is dedicated to sugar color measurement. It will present a collaboration made between NOVASEP and INDATECH. The sensor is directly integrated on filtration units that measure several wavelengths by LED technology.

Our specialist will present how to calibrate a sensor from the laboratory. After the calibration, he will explain the placement directly on the production line. An essential step for realizing a real time measurement in the process allowing an interaction and a piloting.

To know the composition of your liquids with accuracy, the SPOT4Line solution uses the LED light beam that penetrates the liquid to bring out its “optical fingerprint” and validate in real time several parameters.

INDATECH is a recognized player in spectroscopy and holder of numerous patents. It has designed SPOT4Line, the first multi-angle LED spectrometer dedicated to the analysis of all industrial liquids. Based on spectral scattering of light, SPOT4Line is completed by the patented SAM-SPEC Spatially Resolved Spectroscopy (SRS) technology to assign an optical signature to the liquid measured.

Webinar on physico-chemical characterization of compaction/granulation products

With this Webinar on physico-chemical characterization, you can find out how to use hyperspectral imaging for quick identification of your samples.

This webinar will focus on physico-chemical characterization using NIR spectroscopy in industrial pharmaceutical, chemical or agri-food environments in order to characterize the granulation process. Also, NIR spectroscopy ensures easier continuous handling and better homogeneity of the blend under consideration. The disparity of the physico-chemical properties of the samples and their diversity require the measurement of several samples in a single operation. Which is why NIR hyperspectral imaging is used with Hypereal.

Then, it will be necessary to discover and characterize all the key steps in the compaction and granulation process during the process development phases. That is why this webinar will show how a hyperspectral imaging system can be used for physico-chemical characterization of these intermediate compacted products by indicating the compaction force applied to a powder blend, the proportion of API in the blend or the granule size.

The results are provided as an image, allowing the operator to gain a fuller understanding for optimization of the process and the machine.

HypeReal can be used to indirectly assess the chemical composition of the samples, their residual moisture content and other critical quality criteria, without destroying or modifying the sample and without using toxic reagents.

The unique HypeReal inspection system developed by INDATECH is an ideal tool for quick, non-destructive, laboratory-scale analyses of solid dosage forms.

Webinar on the use of NIR spatially-resolved spectroscopy for real-time monitoring of low-dose tablet formulation

With this webinar on NIR spatially-resolved spectroscopy, find out how to use NIR SRS spectroscopy as an effective PAT tool for the inspection of tablets with a low-dose formulation.

With this webinar on NIR spatially-resolved spectroscopy, find out how to use NIR SRS spectroscopy as an effective PAT tool for the inspection of tablets with a low-dose formulation.

At this webinar on NIR spatially-resolved spectroscopy, we will be presenting the results of Residence Time Distribution (RTD) experiment. Tracers are used to represent the dynamics of the continuous processes. This is an appropriate methodology allowing control strategies. For this, the tracer must be selected appropriately. However, the selection criteria require similar behavior between the bulk material and the tracer.

Indeed, recent progress in increasing the sensitivity of PAT measurements allows “small” step to be made in the composition of the formulation. In this study our speaker, Carlos Ortega-Zuniga, used a low-dose formulation as the target. He induced small step changes to the API concentration in a continuous process.

For this experiment, the industrial tablet press is equipped with an NIR SRS system. The measuring instrument is therefore positioned after production of the tablets so that the individual tablets can be inspected. After these tests, the NIR SRS system proved sensitive to the capture of step changes of -/+ 0.50 % p/p of API.

To sum up, this work by a postgraduate from Rutgers University has demonstrated that small step changes can be performed to extract the RTD information. As a result, we can confirm that the inspection of low-dose tablets is possible using NIR SRS technology as the PAT tool.

For this purpose CA INDATECH has designed and developed patented technology combining NIR spectroscopy and hyperspectral imaging. This versatile analytical system is ideal for use in the laboratory or on continuous production lines. To learn more about our solution, attend to our webinar on December 15th, at 4 PM.
