Transforming sample preparation




In small-molecule analyses, complex sample matrices, price pressures and stringent analytical method requirements place difficult demands on separation scientists. Using ‘good enough’ sample preparation approaches that fail to adequately prepare samples can lead to shortened column lifetimes and poor method sensitivity and precision due to ion suppression or enhancement. To overcome these issues, Waters has developed a new, easy-to-use, streamlined approach that is based on a water-wettable, reversed-phase sorbent. This new and exciting product produces high recoveries, improved sample flow and reduced matrix effects in far less time than typical solid-phase extraction protocols.

What will you learn?

  • How to shorten SPE protocols without sacrificing cleanliness or recoveries
  • How to speed up SPE processing and avoid sample re-analysis
  • How to simplify current sample preparation approaches in your lab to save both time and money
