New aspects in fragmentation of peptide nucleic acids: comparison of positive and negative ions by electrospray ionization Fourier transform ion cyclotron ... The use of peptide nucleic acids (PNAs) is steadily increasing in biochemistry and diagnostics. So far, PNAs have mostly been investigated usin...
This work evaluated the use of electrospray ionization in both negative ion mode (ESI-) and positive ion mode (ESI+) for the characterization of DOM extracted from nine terrestrial sources using Fourier transform ion cyclotron mass spectrometry (FT-ICR-MS). The compositing of the peaks from ESI...
The mass spectrometer was operated in both positive and negative electrospray ionization (ESI+/ESI − ) mode. The UPLC-quadruple/time-of- flight mass spectrometry ESI+ and ESI − raw data were analyzed by the MarkerLynx Applications Manager version 4.1 (Waters Corp., Milford, MA, USA) and...
Dyanmic ion trapping for Fourier-transform ion cyclotron resonance mass spectrometry: Simultaneous positive- and negative-ion detection The conventional static electric potential used to trap ions fro fourier-transform ion cyclotron resonance (FTICR) mass spectrometry has been replaced by a...

Investigation of electrospray ionization and electrostatic focusing devices using a three-dimensional electrospray current density profiler A novel instrument for profiling the current density of nanoelectrospray ionization plumes in three dimensions has been developed. A hemispherically-shaped... JW Thompson,...
However the protective efficacy of Channel Catfish immunized by immersion was not good, because ofpositive ionand organics in water. The sensitivity for the measurement of chloropicrin by the modes ofpositive ionand negative chemical ionization was compared. ...
Prior to the diagnosis of schizophrenia, patients typically display attenuated positive, cognitive, and negative symptoms, during a period known as the prodrome1. These symptoms increase in severity until they meet the clinical criteria for schizophrenia. It is possible to identify those people who ...
