Duration: Approximately 40 minutes

Matrix-rich samples often require extensive sample preparation when analyzed with HPLC and UHPLC. This is a substantial time and cost factor. A robust column material enabling a simplified sample preparation will save time and improve the lab productivity.
The performance of HPLC columns has improved dramatically in recent years, particularly in terms of separation power as measured by the number of theoretical plates per meter. The improvement in performance has been achieved primarily by a reduction in particle size.

By viewing this presentation you will...

  • Understand the challenges for matrix-rich sample analysis using HPLC and/or UHPLC and how to overcome them
  • Learn how to leverage lab efficiency by simplifying the HPLC workflow using monolithic silica columns.

Petra LewitsPetra_Lewits_80
(Global Product Manager for Analytical Chromatography, HPLC columns,
Merck KgaA Darmstadt, Germany

Petra has worked with chromatography for more than 30 years. She started her career in separation science in 1983 using several chromatographic methods, including HPLC, TLC, GC and solid-phase extraction (SPE), for food control in a governmental institution lab. In 1986 she joined Merck’s pharmaceutical R&D and QC department (Merck KGaA, Darmstadt, Germany) where she developed HPLC methods for R&D and QC of pharmaceutical APIs and formulations as well as for diet convenience foods. From 1991 she has supported customers in different positions with technical and application-related inquires in Europe as a sales specialist for HPLC instruments, also providing technical support for chromatography and complaint management. Since 2002 she has been a Global Product Manager for Analytical Chromatography (HPLC). In 2014 she began focusing on thin-layer chromatography (TLC). Since April 2018 Petra has had global responsibility for analytical HPLC columns at Merck.

The life science business of Merck KGaA, Darmstadt, Germany operates as MilliporeSigma in the U.S. and Canada.
