THIS PRODUCT IS FOR THE MEASUREMENT OF SIZE, MOLECULAR WEIGHT, PARTICLE CONCENTRATION AND ZETA POTENTIAL OF DISPERSED PARTICLES AND MOLECULES. THE SYSTEM INCLUDES MAXIMUM 10MW HENE LASER (633NM) WITH HIGH SENSITIVITY APD DETECTOR. THE SIZE/MOLECULAR WEIGHT BY DLS/SLS OF THE SYSTEM IS MEASURED AT 173-DEGREES USING NON-INVASIVE BACK SCATTER, AND 90-DEGREE DLS/SLS MEASUREMENTS ARE ALSO POSSIBLE. THE SYSTEM ALSO INCLUDES ADAPTIVE CORRELATION FOR FASTER, REPRODUCIBLE, DLS MEASUREMENTS WITH NO DATA LOSS. THIS PRODUCT ALSO INCORPORATES MULTI-ANGLE DYNAMIC LIGHT SCATTERING MEASUREMENTS FOR HIGHER RESOLUTION DLS ANALYSIS AND PEAK PARTICLE CONCENTRATION ANALYSIS OF SAMPLES <500NM. THERE IS ALSO ZETA POTENTIAL ANALYSIS THAT INCORPORATES M3-PALS AND CONSTANT CURRENT ZETA MODE FOR MEASUREMENT OF ZETA POTENTIAL DISTRIBUTIONS AND IMPROVED DATA QUALITY IN CONDUCTIVE MEDIA. THE PRODUCT ALSO INCLUDES AN APPLICATION SOFTWARE WITH EASY TO USE METHOD BUILDER FOR MEASUREMENT CONTROL AND DATA ANALYSIS WITH ADVANCED DATA QUALITY ASSESSMENT AND ADVICE SYSTEM. THIS LIGHT SCATTERING INSTRUMENT IS FOR USE IN A LABORATORY. THE PRODUCT CAN BE USED IN MONITORING VIRAL CONCENTRATION.
