DYNAMIC LIGHT SCATTERING SIZE RANGE FULL

Unscrew to open the microfilter, add a 0.2µm filter membrane in between the 2 halves, and screw the microfilter tight. Filter your sample whenever possible before applying it to the filter-kit.If scattering is present, then the cuvette is not clean). Clean the cuvettes before and after use with water and ethanol dry the cell using 'air-it.' (It is a good idea to fill a cuvette with water and check for light scattering before testing your sample.Start the Dynamics program on the computer (icon on desktop). Turn on the measurement unit, then turn on the power unit, let it warm up for several minutes.Protocol for DynaPro99 Molecular Size Instrument (Dynamic Light Scattering) Measurements take only a few minutes and samples are generally recoverable.įor questions about getting started with a Dynamic Light Scattering project contact Dr. It measures the hydrodynamic radius down to 1.0nm and provides the distribution independent of solvent conditions so that the macromolecular behavior may be studied in virtually any solution condition. The DynaPro is highly sensitive in the detection of aggregation - even trace amounts - which often go undetected with other techniques such as gel filtration chromatography. The DynaPro-MS (MicroSampler) is an ultra-sensitive instrument combining 45 µl sample volumes with the highest sensitivity available over the 0.5 nm - 200 nm radius size range. Identifies small amounts of aggregation in protein or polymer samples (Measures particle sizes down to 1 nm diameter.Simple or no sample preparation, measures the material in the native state including high concentration and turbid samples.

DLS is ideal for directly measuring the full particle size distribution! This method is preferred as compared to Laser Light Scattering when analyzing materials in the nanometer size range. DLS which measures at a fixed angle can determine the mean particle size in a limited size range, while multi-angle DLS can determine the full particle size distribution. This method determines particle size based on the scattering of light for particles in the sub-micron to low nanometer range. This method utilizes the effect of Brownian motion to calculate the hydrodynamic radius of a molecule in solution where its hydrodynamic size depends on the mass of the material and its conformation.
