Infometrix would like to recognize a former employee for being named as an AAAS Fellow in 2022. Deborah Illman played a critical role in the beginnings of Infometrix in the late 1970s and early 1980s and coauthored one of the first books in the field with Muhammad Sharaf and Bruce Kowalski. Debbie went from Infometrix to help create and manage the Center for Process Analytical Chemistry in the mid 1980s, now rebranded the Center for Process Analysis and Control. She has a long history of contributions to the teaching of graduate students and undergraduates focusing mainly on the topics of science communication, management of multidisciplinary projects, and decision making. A former Associate Editor for Chemical and Engineering News, Debbie has reached and influenced many in the world of science.
Announcements
PEFTEC 2022
Join us at PEFTEC 2022. This year it will be hybrid and access to the exhibition and all of the technical sessions is free of charge.
Keynote speaker, Brian Rohrback of Infometrix, Inc. will present his talk on Streamlining the Use of Chemometrics
June 8th at 13:15 CEST
Artificial intelligence and machine learning are inevitable results of the work driven by the consumer side of our economy. The question is not whether it will impact refining and chemical plant operation, but how soon and how long it will take for the benefits to outstrip the costs. The goal is to distinguish between vision and hallucination and to provide some practical guidance for making progress in this complicated set of fields. There are three categories of measurements that provide us with the data that will form the basis for any interpretation system: single-purpose sensors, chromatographs, and spectrometers. Multivariate analysis can be used in all three categories and, in fact, is critical to interpreting output from any type of spectrometer. We can easily demonstrate that the use of multivariate analysis for each of the three groupings, even these data sources assembled together, gives faster response, improved flow of information derived from these data, and a significant leg up for process understanding. This information is available and is nearly cost-free.

solutions. For more information, email info@infometrix.com.
Upcoming Events 2022
We miss in person relationships and live experiences that are not available with virtual and hybrid meetings. Virtual platforms have their issues which makes us desire more for in person gatherings. We’re still not back to normal but we are easing our way back. Hope you feel the same and will join us at these upcoming events to share and engage in a valuable discussion.

Agile Process Analytics
Application knowledge and chemometrics play a vital role in the processing of all types of multivariate data into application-specific information and has been doing so for at least 50 years. There has been a not-so-subtle shift in thinking as we integrate basic concepts and the occasional hallucination in the data mining, artificial intelligence, machine learning worlds. The target is to identify combinations of our technical tools to augment or replace tasks that consume brainpower where timely response is valued, and profits are at risk. The biggest focus of chemometrics has been in the calibration of optical spectrometers. It is worth considering the subtasks:
- Optimizing the instrument settings for a given application;
- Optimizing the method parameters – preprocessing, transformations, wavelength ranges;
- Handling of calibration transfer; and
- Optimizing models for inliers and rank in pursuit of routine processing and adjusting to changes in ingredients and unit operation.
The first two tasks are a set-once method development and the third may be generic across all applications. This paper tackles subtask 4 with a project that combined traditional approaches in statistics, database organization, pattern recognition, and chemometrics with some newer concepts tied to better understanding of data mining, neurocomputing, and machine learning. The future goal is to automate spectroscopy calibrations such that it is possible to have instrument systems tune themselves.
