New Publication: Collision cross section calibrants for negative ion mode traveling wave ion mobility-mass spectrometry

malic_acid_tocCollision cross section calibrants for negative ion mode traveling wave ion mobility-mass spectrometry. Jay G. Forsythe, Anton S. Petrov, Chelsea A. Walker, Samuel J. Allen, Jarrod S. Pellissier, Matthew F. Bush, Nicholas V. Hud, Facundo M. Fernández. Analyst 2015, 140, 6853-6861. (Link|PUBMED)

Abstract. Unlike traditional drift-tube ion mobility-mass spectrometry, traveling-wave ion mobility-mass spectrometry typically requires calibration in order to generate collision cross section (CCS) values. Although this has received a significant amount of attention for positive-ion mode analysis, little attention has been paid for CCS calibration in negative ion mode. Here, we provide drift-tube CCS values for [M − H]− ions of two calibrant series, polyalanine and polymalic acid, and evaluate both types of calibrants in terms of the accuracy and precision of the traveling-wave ion mobility CCS values that they produce.

Goodbye to Chrissy Stachl and Nora Munger

The Bush Lab says goodbye to Chrissy Stachl and Nora Munger. Chrissy recently graduated from the University of Washington as a Gates Millennium Scholar with a Bachelor of Science in Chemistry and Neurobiology. She will spend next year as a DAAD Scholar in the laboratory of Gert von Helden at the Fritz Haber Institute in Berlin. Nora Munger was an Amgen Scholar this summer and will return to Carleton College to complete degrees in Chemistry and Art History.
