WebTime of flight ( ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate). The operation of the FID is based on the detection of ions formed during combustion of organic compounds in a hydrogen flame. The generation of these ions is proportional to the concentration of organic species in the sample gas stream. To detect these ions, two electrodes are used to provide a potential difference. The positive electrode acts as the nozzle head where the flame is produced. The other, negative electrode i…
Web10 mrt. 2024 · Membrane potential is the voltage or potential difference across the cell membrane. The potential difference is caused by the hydrophobic membrane separating charges, acting as both a capacitor and resistor to the movement of charged ions across it.
