## Abstract For the analysis of hydrogen and helium in solids and thin films by secondary ion mass spectrometry, the use of Cs^+^ primary ions in conjunction with the detection of HCs^+^ and HeCs^+^ molecular ions is proposed. For both species, detection limits of the order of 10^19^ atoms cm^β3^ a
Described herein is the synthesis of all positional isomers of partially methylated and acetylated or benzoylated 1,4-anhydro-D-ribitol. The benzoates are generated simultaneously from 1,4-anhydro-D-ribitol by sequential partial methylation and benzoylation or sequential partial benzoylation and met
