THIS PRODUCT IS FOR THE MEASUREMENT OF SIZE, MOLECULAR WEIGHT AND ZETA POTENTIAL OF DISPERSED PARTICLES AND MOLECULES. THE SYSTEM INCLUDES MAXIMUM 4MW HENE LASER (633NM) WITH HIGH SENSITIVITY APD DETECTOR. THE SIZE/MOLECULAR WEIGHT BY DLS/SLS OF THE SYSTEM IS MEASURED AT 90-DEGREES. THE DYNAMIC LIGHT SCATTERING (DLS) WILL DETERMINE THE SIZE OF PARTICLES IN A SAMPLE. FROM <1 NM TO 10 PM. THE SYSTEM HAS ADAPTIVE CORRELATION FOR REPRODUCIBLE DLS MEASUREMENTS WITH NO DATA LOSS. THE SYSTEM ALSO HAS ZETA POTENTIAL ANALYSIS THAT INCORPORATES M3-PALS AND CONSTANT CURRENT ZETA MODE FOR MEASUREMENT OF ZETA POTENTIAL DISTRIBUTIONS AND DATA QUALITY IN CONDUCTIVE MEDIA. THE SYSTEM ALSO INCLUDED AN APPLICATION SOFTWARE WITH ITS EASY TO USE METHOD BUILDER FOR MEASUREMENT CONTROL, DATA ANALYSIS WITH ADVANCED DATA QUALITY ASSESSMENT AND AN ADVICE SYSTEM. THIS LIGHT SCATTERING INSTRUMENT IS FOR USE IN A LABORATORY. THE PRODUCT IS AN ENTRY LEVEL MODEL, FOR ROUTINE SAMPLE INVESTIGATIONS. THE SYSTEM UTILIZES 90 DEGREES MEASUREMENTS TO GENERATE PARTICLE SIZE AND ZETA POTENTIAL DATA FOR MEASURING LARGER SIZED PARTICLES. THE SYSTEM ALSO IDENTIFIES AND SEPARATELY CLASSIFIES ROGUE LARGE PARTICLES SO THAT THEY DO NOT INFLUENCE THE CONSISTENTLY PRESENT PARTICLE SIZE RESULT PROVIDING A MORE REPRESENTATIVE VIEW OF THE SAMPLE. THE SYSTEM CAN BE USED IN THE SIZING OF COLLOIDAL SILICA.
