Description:
<jats:p>Very sensitive laser light scattering equipment has been designed to be used in conjunction with chromatographic column separation. The system is prealigned and fully computer controlled. It gives the hydrodynamic radius of the eluting particles on line during separation. With a He-Ne laser source, the sensitivity is reached with four optical channels and four correlation functions of the scattered light measured in parallel with a special correlator.</jats:p>
