Ionization techniques in mass spectrometry coupled to separations techniques Type of MS analysis Advantages Negative chemical (i) It provides more sensitivity at low ionization concentration (pg) based on the stability of
electronegative moieties.
At a pH below the PZC of the oxides, the soil becomes electropositive, which makes it possible for the
electronegative functional groups of soluble organic anions to bind to the electropositive domains of soil particles.
In bacteria, the
electronegative charge of the cell wall is due to lipopolysaccharides in Gram-negative bacteria and teichoic acid in Gram-positive organisms.
Similarity between naturally occurring modified desiaiylated,
electronegative and aortic low density lipoprotein.
On condition that the interference from the surface adsorbed water is eliminated, the broadened peaks in the wavenumber range of 3600-3100 [cm.sup.-1] belong to the out-of-plane stretching vibration of the hydroxyl-containing hydrogen bonds (-OH), in which the hydrogen atoms are susceptible to mutually attracting apparent
electronegative oxygen atoms on the other chemical bonds to form hydrogen bonds.
More
electronegative anions led to better cellulose solubilizing abilities.
Nucleophilicity, interatomic distance between
electronegative heteroatoms, and electron donor capability of heteroatoms are all important model variables.
Apart from the fact that the proton is attached to a highly
electronegative element, the effect of neighboring atoms contributed to a high decrease in electron density around the imine proton (Sankar et al., 2010; Jursic et al., 2002).
