| FID: Wikipedia: FID |
Flame ionisation detector Most prevalent detector in gas chromatography (can detect all substances which contain at least one CHn unit). |
||
| flash point: Wikipedia: flash point |
The lowest temperature at which a mixture of the substance with air under normal pressure can be ignited with e.g. a spark. Flash points can be measured with an open cup (o.c.) or closed cup (c.c.) method. Values measured with an open cup are usually higher than those measured with a closed cup. | explosion limits, autoignition temperature | |
| fluorescence detector: Wikipedia: fluorescence detector |
Detector for (dissolved) substances with fluorescent molecular building blocks (e.g. polycyclic aromatics) and that exhibits high sensitivity. | ||
| FPD: Wikipedia: FPD |
Flame photometric detector: very selective gas chromatographic detector for compounds containing S or Sn atoms. |

| free enthalpy: Wikipedia: free enthalpy |
Thermodynamic state function that can be calculated from enthalpy and entropy of a chemical reaction. The change in free enthalpy of an isothermic and isobaric reaction determines the direction of that reaction. | heat of reaction |
