Right angle light scattering detectors

Viscosimetry-right angle light-scattering detector.352... 

Adjust the forward and right-angle light-scatter detectors so that the granulocyte population IS clearly visible see Chapter 32, Section 3.5.3., Fig. 2). Gate on the granulocyte population, and exclude the lymphocytes and monocytes from analysis. 

The parameter [Equation (18)] is used to take into account deviations from 0 conditions (23). This approach has been evaluated with good success using polystyrene samples (21,24). If a viscosity detector is used in series with a right-angle light-scattering detector. Equation (16) can be used in an iterative procedure to correct for angular asymmetry (see p. 116).

Fig. 1. An incident electromagnetic field of intensity, having an associated electric field, D, induces dipole osciUation in the absorbers. The transmitted intensity, is reduced by absorption of the radiated (scattered) light, a portion, J, is shown here detected in a conventional right-angle configuration with coUection solid angle AQ (a) Schematic of the absorption/scattering where 1q = (1/2)cCq E in W/m (b) plot of scattered light, J, vs frequency where Ig = lQNl da/d )A and AQ is proportional to (detector area)/R and (c) plot of transmitted light, vs frequency where...
