Web(2) When the characteristic size D of particles is uot small compared with in- cident wavelength, the Rayleigh approximation is not valid. The exponent to be given to X in the scattering law is in general a complicated function of D/X.' (3) When the particle size is not constant with time, or when particles aggregate during measurement, Webdrift, while the traditional approach uses only the periodic measurements of the calibration standard as the diagnostic. The lower part of Figure 1 depicts the experiment design for our example of five samples using this more efficient drift correction approach. Not only is the experiment shorter in Webby using the so-called B-train systems where integrator drift correction was implemented by using short integration periods (maximum of a few seconds) combined with reference markers based on Nuclear Magnetic Resonance (NMR) or Ferrimagnetic Resonance (FMR) technology [12–15]. In this manner, a drift of about 2.3 ppm/s over a time scale of 1 ... copying code from teams
