Sample Preparation for Clinical Liquid Chromatography-Mass Spectrometry Assays

Explore Preparation and Automation Options

This webinar encompasses various sample preparation options for liquid chromatography-mass spectrometry (LC-MS) assays. It highlights the importance of sample processing in the clinical laboratory environment and illustrates the fit-for-purpose application of processing techniques in clinical mass spectrometry.

Dr. Clarke will discuss the theory behind different specimen preparation methods and the strengths and weaknesses of each, as well as uncover opportunities for automation. Topics include the role of upfront sample management for blood and urine specimens, microsamples, and  handling dried specimens. There will also be a basic introduction to the application of LC-MS approaches for various specimen sources, i.e., alternative matrices, and elaboration about new technologies and automated alternatives for sample processing.

Learning Objectives

This webinar will help you:

• Describe various pain points and challenges in clinical LC-MS
• Discuss the impact on LC-MS assay performance of various specimen preparation approaches
• Apply a fit-for-purpose approach to the selection of a specimen preparation method
• Explain alternative specimen and microsample types and critical specimen preparation limitations
