A look back at this innovator’s career and her efforts to develop and popularize gas chromatography (GC), particularly for biomedical research.

This article is an adaptation of one written in the German publication Nachrichten aus der Chemie and discusses how gas chromatography instrumentation, columns and techniques have improved over the past 10–15 years, making even relatively new equipment obsolete for many applications. In particular, the authors look at how older equipment is unsuitable for fast GC, better trace analysis and comprehensive multidimensional GC.

Developments in gas chromatography instrumentation, columns, and performance during the past 10 years.
