“…Glycerol thermally decomposes principally by the loss of two H 2 0 molecules to form the conjugated molecule acrolein, whereas hydroxyacetone, acetaldehyde, and formaldehyde are formed in lesser amounts [48]. These carbonyl-containing products react further and condense with glycerol to form acetals and ketals [48]. Experimental evidence for thermallike, bombardment-induced decompositions comes from a study by Lehmann et al [49Jwho showed that formaldehyde is produced during bombardment of glycerol and then reacts with the amino group of added oligopeptides to form a Schiff's base.…”

“…All have elemental compost- (Table 1) suggest that there is, in addition to the loosely bound species that lose a glycerol molecule, a covalent population of ions produced by reactions of unsaturated coupling products and glycerol. By analogy with solution and pyrolysis chemistry of glycerol [48], the products are likely to be acetals or ketals formed from gas-phase acid-or base-catalyzed condensations (for the protonated or deprotonated oligomers, respectively) of glycerol with aldehydes or ketones produced as a result of water loss. One possibility is illustrated in Scheme IV.…”

Accurate mass measurements were used to assign elemental compositions and tandem mass spectrometry was used to characterize the peak-at-every-mass background ions produced by kiloelectron-volt-particle bombardment of neat fast-atom bombardment matrices. The majority of the background ions observed in the mass spectrum of neat glycerol was identified. On the basis of the experiments with glycerol, a theory for the formation of background ions is presented. Results are discussed according to the chemical and physical changes that ygoe;on-volt-particle bombardment produces in the matrix.

“…Registry No. H4Y, 60-00-4; H3YR, 85479-87-4; H2YR2, Sir: A recent paper by Oppenheimer, Capizzi, Weppelman, and Mehta (1) shows the degree of sensitivity of the "lowest limit of reliable assay measurement" (LLORAM) to the choice of criteria and to the methods of calculation employed. In particular these authors demonstrate the necessity of taking into account any nonuniformity of measurement variance along the calibration (standard) curve if this occurs.…”
