THIS PRODUCT IS FOR THE MEASUREMENT OF SIZE, MOLECULAR WEIGHT AND ZETA POTENTIAL OF DISPERSED PARTICLES AND MOLECULES. THE SYSTEM INCLUDES MAX.10MW HENE LASER (633NM) WITH HIGH SENSITIVITY APD DETECTOR. THE SIZE/MOLECULAR WEIGHT BY DLS/SLS 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 FASTER, 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 PRODUCT ALSO AN APPLICATION SOFTWARE WITH A METHOD BUILDER FOR MEASUREMENT CONTROL. THE SYSTEM ALSO ALLOWS DATA ANALYSIS WITH ADVANCED DATA QUALITY ASSESSMENT AND ADVICE SYSTEM. THIS LIGHT SCATTERING INSTRUMENT IS FOR USE IN A LABORATORY. THE PRODUCT IS AN ENTRY LEVEL MODEL FOR USE WITH MORE CHALLENGING SAMPLES. THE SYSTEM UTILIZES 90 DEGREES MEASUREMENTS TO GENERATE PARTICLE SIZE AND ZETA POTENTIAL DATA FOR MEASURING LARGER SIZED PARTICLES. THE SYSTEM CAN BE USED FOR PROTEIN RESEARCHERS TO CONFIRM THAT SAMPLES MEET QUALITY REQUIREMENTS AND THAT PRODUCTION AND PURIFICATION PROCESSES ARE OPTIMIZED.
