Chemometrics in Spectroscopy - Linearity in Calibration: How to Test for Non-linearity

Spectroscopy spoke with Uwe Karst, a full professor at the University of Münster in the Institute of Inorganic and Analytical Chemistry, to discuss his research on hyphenated analytical techniques in battery research.

An interview with Charles Wilkins, the winner of the 2013 American Chemical Society Division of Analytical Chemistry Award in Chemical Instrumentation, sponsored by the Dow Chemical Company.

Spectroscopy sat down with Landulfo Silveira Jr. of Universidade Anhembi Morumbi-UAM and Center for Innovation, Technology and Education-CITÉ (São Paulo, Brazil) to talk about his team’s latest research using Raman spectroscopy to detect biomarkers of cancer in canine sera.

This new study examined food contact materials (FCMs) and how mass spectrometric techniques have been used to measure harmful substances from FCMs that end up in food.

This column is the continuation of our previous column that describes and explains some algorithms and data transforms beyond those most commonly used. We present and discuss algorithms that are rarely, if ever, seen or used in practice, despite that they have been proposed and described in the literature.

By providing automated tools and guidance, an ECS would aim to streamline the calibration process, improve calibration transfer, enhance operator efficiency, and improve the overall consistency and reliability of analytical results produced using advanced chemometrics and machine earning techniques.
