Small molecule ambient mass spectrometry imaging by infrared laser ablation metastable-induced chemical ionization
Abstract Presented here is a novel ambient ion source termed infrared laser ablation metastable-induced chemical ionization (IR-LAMICI). IR-LAMICI integrates IR laser ablation and direct analysis in real time (DART)-type metastable-induced chemical ionization for open air mass spectrometry (MS) ionization. The ion generation in the IR-LAMICI source is a two step process. First, IR laser pulses …

Microfluidics with MALDI analysis for proteomics
J. Lee, S.A. Soper, K.K. Murray, “Microfluidics with MALDI analysis for proteomics–a review,” Anal. Chim. Acta. 649 (2009) 180–190. doi:10.1016/j.aca.2009.07.037. Abstract Various microfluidic devices have been developed for proteomic analyses and many of these have been designed specifically for mass spectrometry detection. In this review, we present an overview of chip fabrication, microfluidic components, and …

Is Wikipedia the Public Face of Mass Spectrometry?
Presented at the 57th ASMS Conference on Mass Spectrometry, Philadelphia, Pennsylvania, May 31th to June 4th 2009 Introduction Wikipedia is a web resource that is described as “the free encyclopedia that anyone can edit.” The low barrier for participation is both one of the best and worst features of the site. The drawbacks of easy …
