Using the Mie theory of light scattering for homogeneous spheres, the low-angle,
high-gain light scatter measurement is converted into cell volume and the high-
angle, high-gain light scatter measurement is converted into refractive index (n).
The following histograms and cytograms are used for platelet analysis:
Platelet X
histogram is formed from the high-angle (5° to 15°), high-gain light
scatter signals.
Platelet Y
histogram is formed from the low-angle (2° to 3°), high-gain light
scatter signals.
Platelet Vol
histogram shows the distribution of platelets by cell volume.
Platelet PM
histogram shows the distribution of platelets by dry mass.
Platelet PC
histogram shows the distribution of platelets by refractive index.
PLT Scatter
cytogram is formed by plotting the high-angle (5° to 15°), high-gain
light scatter signals along the x axis and the low-angle (2° to 3°), high-gain light
scatter signals on the y axis.
PLT Volume PC
cytogram is formed by plotting the refractive index of platelets
(PC) along the x axis and the platelet volume on the y axis.
