Quadrupole Time

Compounds are transported from the ESI source in a carrier gas (N 2) into a DMS cell that consists of two electrodes that apply a high-voltage radio frequency. Differences in the chemical structure of ions results in differential mobility as they move towards either electrode in the gas phase environment of the cell. 43 Get price

Revising the BFIHOST catchment descriptor to improve UK

The base flow index (BFI) is a widely applied, broad-scale measure used in the UK for measuring variation in the low-flow regimes of gauged catchments. The index was originally proposed in the 1980s by Gustard et al. and is a simple separation algorithm that disaggregates the daily mean flow record for a catchment into low- and high-frequency components.
