Application Note: High Resolution and Precise Mass Accuracy: A Perfect Combination for Food and Feed Analysis in Complex Matrices
12 August 2009

In complex sample matrices such as food, feed, hair, and honey, limited resolution leads to inaccurate mass measurements caused by unresolved background matrix interferences. This application note shows a full scan screening approach using a novel single stage Orbitrap™ mass spectrometer coupled to U-HPLC, capable of providing high mass accuracy at resolutions of up to 100,000.
