Bruce R. Kowalski: The Maverick Mind Behind Chemometrics

Bruce R. Kowalski: The Maverick Mind Behind Chemometrics

In this Icons of Spectroscopy article, we take a look at the life and impact of Bruce Kowalski (1942-2012), a pioneering analytical chemist, who played a big role in developing chemometrics—the use of math to make sense of complex chemical data—and his work in data analysis, teaching, and software that has had a lasting influence on both academic and industrial chemistry.

Bruce R. Kowalski, also the co-founder of Infometrix, was a pioneer of chemometrics, known for advancing multivariate statistics and data analysis in chemistry. This article honors his legacy, from shaping chemometric theory and education to co-founding the Journal of Chemometrics. His global impact endures through mentorship, software tools, and leadership in analytical chemistry.

IMAGE ’25 – International Meeting for Applied Geoscience & Energy

IMAGE '25 MeetingVenue: George R. Brown Convention Center, Houston, TX

Date: August 24-28, 2025

Short Course:  SC-01: Chemometric Tools to Establish Petroleum Systems, Predict Physical Properties, and De-Convolute Mixed Production

Course Leaders: Dr. Kenneth Peters from LSB NExT Training and Brian Rohrback from Infometrix will be leading the short course on August 24th.

This one-day course is for all geoscientists who want to extract hidden information from substantial amounts of chemical and physical data using multivariate statistical (chemometric) tools. The course emphasizes applications rather than the mathematics of various chemometric methods and will include a demo version of Pirouette 5.0 chemometric software. Case studies focus on the following topics of immediate interest to geoscientists:

• Hierarchical cluster analysis (HCA) and principal component analysis (PCA) of biomarker and stable isotope data for oil-oil and oil-source rock correlation to establish petroleum systems.
• Quantitative regression analysis of chromatographic peaks by alternate least squares (ALS) to de-convolute mixed oils derived from two or more sources. In exploration, ALS identifies mixed oils (e.g., pre-salt and post-salt oils in the Middle East and Southern Atlantic). In production, ALS allows allocation of mixtures originating from multiple reservoir zones.
• Prediction of physical properties by partial least squares (PLS) of data obtained by micro-analytical techniques. PLS allows investigators to predict API gravity, sulfur, and viscosity for reservoir zones where only small samples of cuttings from storage are available for analysis.

Minnesota Chromatography Forum 2025 – Join Us at Booth #35

Venue: Heritage Center of Brooklyn Center, Minneapolis, MN

Date: Jun 10 – 12, 2025

Location: Booth #35

Brian Rohrback of Infometrix will be presenting at the Minnesota Chromatography Forum  on Wednesday, June 11th. 

Title: Demystifying Chemometrics for use in Chromatography

Abstract:

Chemometrics technology is often neglected in chromatographic analysis, but the technology is useful in both signal processing and automated interpretation.  The primary application is to handle the problem of peak migration.  Adjusting for retention time variability can be done automatically at the end of the run and it does not require internal or external standards. It also can be used well after data collection to update a chromatographic library.  Ultimately this leads to simplified methods development, improved instrument calibration, and effective management of chromatographic databases. Chemometrics also allows the interpretation of a chromatographic pattern to be automated, leading to more complex quality monitoring exercises to be brought on-line or near-line.
