Cuvette photocentrifuges

An alternative procedure is to use several wavelengths and deconvolute the resulting set of linear equations that develop in order to find the size distribution. This procedure was applied by Niemann and Weichert who used a modified Phillips-Twomey algorithm [44,45]. Their photo- 

Horiba CAPA-700 covers the size range 0.01 to 300 jxm, automatically selecting the best of five operating conditions, involving the three modes enumerated above, at centrifuge speeds from 300 to 10.000 rpm. 

Horiba CAPA-300 is a more economical version covering the size range 0.04 to 300 jam. 

Seishin offer three versions of their micron photo-sizers covering the size range 0.1 to 500 jim, the SKC-2000, the SKC-3000 and the SKC-5000.

Photocentrifuges are available in both disc and cuvette configuration. The former are normally used in the line-start mode and the latter in the homogeneous mode. The line-start mode has a much higher resolution...
