SPE Protocol for Extraction of Urinary Catecholamines and Metanephrines

17 February 2017

This application note describes a mixed-mode weak cation exchange SPE protocol for the extraction of catecholamines and metanephrine metabolites from urine prior to LC-MS/MS detection.

 

The described method allows simultaneous extraction of six metabolites, using a high throughput load-wash-elute/no blow down EVOLUTE® EXPRESS method. The method is automated using Biotage® Extrahera™ sample processor (see full details in the application note). High reproducible recoveries were achieved for all analytes.

EVOLUTE® EXPRESS SPE products dramatically improve flow characteristics, and enhance sample preparation productivity. By truly eliminating the need for column conditioning and equilibration, samples can be prepared using a simple, fast load-wash-elute procedure.

Analytes

  • Epinephrine
  • Norepinephrine
  • Dopamine
  • Metanephrine
  • Normetanephrine
  • 3-Methoxytyramine
