## Abstract Peaks for [M + H]^+^ are not observed when electrospray ionization mass spectra of tetrahydropyranyl (THP) ethers are recorded under acidic conditions. However, gaseous [M + H]^+^ ions can be generated from ammonium adducts of THP ethers of primary alcohols by inβsource fragmentation. T

## Abstract Collisionβinduced dissociation of the molecular ions and of some of the fragment ions foremed on ionization of methanol, ethanol and nβpropnol have been studied at high energy resolution in a mass spectrometer. The translational energy lost upon collision and the kinetic energy released
Cluster size distribution and collision-induced dissociation (CID) studies of protonated methanol and protonated methanol-water clusters yield information on the structure and energetics of such ions. Ions were formed at atmospheric pressure in a corona discharge source, and were subjected to CID in
Liquid secondary ion mass spectrometry (LSIMS) and collision-induced dissociation (CID) were used for the characterization of sulfonamide derivatives of meso-tetraphenylporphyrin (TPP). The spectra obtained using LSIMS show abundant molecular ions and fragment ions from losses of the sulfonamide moi
Positive-ion electron ionization (EI), methane chemical ionization (CI) and collision-induced dissociation (CID) mass spectra are reported for a series of pyridone-imines generated from 1-alkyl substituted aminopyridinium salts in a direct-probe inlet. The series comprises 1-methyl-2-imino-and 1-eth
## Collision -induced dissociation (CID) can be effected in the interface region between atmospheric pressure ionization sources and single quadrupole mass analyzers. By varying the electric field in these cone-voltage CID experiments energy-resolved mass spectra can be obtained leading to breakdo
