41. In the external standard method, the FID signal is correlated to the concentration of carbon separately from the analysis. 42. Additionally the damping constant ( decay rate of the signal in the fid ) is not the same for all ions. 43. The most commonly used detectors are the flame ionization detector ( FID ) and the thermal conductivity detector ( TCD ). 44. At Fid E�in, M�el Ca�ch mac Sgannail defeated the army of the D�l Riata, clients of the Cen�l Conaill. 45. Instantaneous monitoring consists of walking over the surface of the landfill, while carrying a flame ionization detector ( FID ). 46. Similar to HPLC, SFC uses a variety of detection methods including FID ( unlike HPLC ) and evaporative light scattering. 47. US military resources can be used as part of a counter-drug ( CD ) component of a FID program. 48. In a covert FID mission, only selected host nation ( HN ) leaders are aware of the foreign support organization. 49. The GC is coupled with either a mass spectrometer detector ( MSD ) or a flame ionization detector ( FID ). 50. Just go to www . pcworld . com / downloads / filedescription / 0, fid , 15782, 00 . asp.
