General description
3,5-Difluorobenzoic acid forms dimers that were stabilized by hydrogen bonds between carboxyl groups. The on-line determination of 3,5-difluorobenzoic acid in water was studied using membrane inlet mass spectrometry with in-membrane preconcentration.

The on-line determination of volatile and semivolatile organic compounds (SVOCs) is reported using membrane inlet mass spectrometry with in-membrane preconcentration (IMP-MIMS). Semivolatile organic compounds in aqueous samples are preconcentrated in a flow-through silicone hollow-fiber membrane inlet held in a GC

A small flip-angle pulse direct polarization is the simplest method commonly used to quantify various compositions in many materials applications. This method sacrifices the sensitivity per scan in exchange for rapid repeating of data acquisition for signal accumulation. In addition
