All the fragmentations of cellulose are present and the base peak of fragmentation appears at m/e 76 due to
positive ion or free radical
positive ion of CS2.
We therefore, analyzed adipose samples for LPC by tandem mass spectrometry in
positive ion mode.
This phenomenon was assumed to be due to the neutralization reaction that happened as a result of the reaction of the stimulated
positive ion with the APmg solution; the AP-mg solution was presented in negativeion.
Both the
positive ions and the pre-amplifier resistor help to reduce the effective potential preventing avalanche.
Some of these secondary electrons may be captured by a
positive ion in a process known as geminate recombination producing a highly excited state that can dissociate into other products.
Ions were detected in the
positive ion mode as sodium adducts [[M + Na].
A JOHN Lewis advertfor a bracelet that promised to counteract "the
positive ions created by modern technology" broke industry rules, a watchdog said.
Pulse ion counting detection is common throughout this series for high-sensitivity and fast response times, with choice of
positive ion only or combined positive and negative ion detection.
CSS Analytical used
positive ion electrospray of a digested Immunoglobulin (IgG).

Positive ion Mean, [micro]g/L 49.
A Perkin-Elmer Sciex API 365 LC/MS/MS benchtop triple quadrupole mass spectrometer operating in
positive ion mode was used to analyze the eluate.
Positive ion detection may be achieved using either a Faraday plate detector or an analogue Channel Electron Multiplier (CEM) if better detection limits are required.
