Relative sensitivity factors definition

Precision FIA measurements typically show low relative standard deviations (RSD) on replicate measurements, mainly due to the definite and reproducible way of sample introduction. This is a very important feature especially for CL, which is very sensitive to several environmental factors and sensitivity relies greatly on the rate of the reaction.

The number of ions i" produced from a gas in the ion source is proportional to the emission current i, to the specific ionization Sggj, to a geometry factor f representing the ionization path inside the ionization source, to the relative ionization probability RlPgaj. and to the partial pressure Pggj. This number of ions produced is, by definition, made equal to the sensitivity Egas times the partial pressure Pg ... 

Because the spectral irradiance 1(1) enters in this definition, the correction factor is a function of total ozone (Q) and solar zenith angle (6), which are the main parameters that determine 1(1). It is obvious from (2), that /ri expresses actually the relative change in the weighted integral when the instrument s sensitivity is used as weighting function instead of the CIE, Because of the involvement of 1(1) in relative sense, 1(1) can be determined from model calculations, as far as total ozone and SZA are known. In practice, lookup tables can be constructed for each instrument, defining the correction factor fd, as functions of total ozone and SZA. These tables can be used thereafter for the conversion of the broadband detectors radiometric output to CIE weighted eiythemal irradiance. 

A definition of a color stimulus includes the chromaticity and a relative intensity measure, the luminance factor. This is determined by the value of Y. This primary has a spectral form which is the same as the eye s overall sensitivity in daylight. Thus, a color can be specified by the three dimensions x, y, Y).
