High-Throughput Quantitative Analysis by Desorption Electrospray Ionization Mass Spectrometry
TL;DR: A newly developed high-throughput desorption electrospray ionization (DESI) source was characterized in terms of its performance in quantitative analysis.

Monitoring Diet Effects via Biofluids and Their Implications for Metabolomics Studies
Haiwei Gu,Huanwen Chen,Zhengzheng Pan,Ayanna U. Jackson,Nari Talaty,Bowei Xi,Candice B. Kissinger,Chester Duda,Doug Mann,Daniel Raftery,R. Graham Cooks +10 more
TL;DR: It should be possible by this procedure to reduce the effect of diet in the biofluid samples for such purposes as disease detection and the number of statistical variables used by monitoring the biochemical variability of particular pathways.

Molecular Ionization from Carbon Nanotube Paper
TL;DR: Ambient ionization is achieved by spraying from a carbon nanotube (CNT)-impregnated paper surface under the influence of small voltages (≥3 V), and organic molecules give simple high-quality mass spectra without fragmentation in the positive or negative ion modes.

Screening of agrochemicals in foodstuffs using low-temperature plasma (LTP) ambient ionization mass spectrometry
Joshua S. Wiley,Juan F. García-Reyes,Juan F. García-Reyes,Jason D. Harper,Nicholas A. Charipar,Zheng Ouyang,R. Graham Cooks +6 more
TL;DR: The results demonstrate that ambient LTP-MS can be applied for the detection and confirmation of traces of agrochemicals in actual market-purchased produce and in natural water samples.

Salt tolerance of desorption electrospray ionization (DESI).
TL;DR: Comparison of the salt tolerance of DESI with that of electrospray ionization (ESI) demonstrated better signal/noise characteristics for DESI, and the already high salt tolerance can be optimized further by appropriate choices of surface and spray solution.
