TL;DR: The addition of an organic acid (formic, acetic or trifluoroacetic acid) was found to strongly influence the retention of the basic amino drugs in these nonaqueous systems and had deep impact on enantioresolution.

TL;DR: In this article, an ionization reagent for the location of double bonds in monoenes was proposed for the identification of insect pheromones, which is highly sensitive to a range of functional groups by isolating [C3H4N]+ from the other acetonitrile ions before reaction with the alkene.
Abstract: Acetonitrile may be used as a chemical ionization reagent gas in ion-trap mass spectrometry for the location of double bonds in functionalized long-chain monoenes. [C3H4N]+, derived from acetonitrile, reacts with carbon–carbon double bonds, generating one or a pair of fragment ions characteristic of the position of the double bond in the chain. Tolerance of a range of functional groups is achieved by isolating [C3H4N]+ from the other acetonitrile ions before reaction with the alkene. Under these conditions, competing processes such as protonation are minimized, and a different mode of fragmentation from that previously observed with unfunctionalized alkenes11 is obtained. The technique is highly sensitive (<0.5 ng), allowing its use in the identification of insect pheromones. Copyright © 1999 John Wiley & Sons, Ltd.

TL;DR: In this paper, three packings with the following surface composition were synthesized on LiChrosorb Si 100, d p 10 μm: [Cu(II) 3-(L -prolyl)propyl] + (packing I), [cu(II] 3-( L -hydroxyprolylpyl) propyl]+ (packing II) and [cu[2] 3-propyl spacer of the bonded ligand, etc., with remaining excess 3-iodopropyl groups (packing III).
