Validation of a Next-Generation Single-Use Turbidity System

Turbidity describes the relative clarity of a liquid as the result of suspended solids. Instruments that measure turbidity typically use a beam of light to detect particles by measuring the difference between the amount of light emitted from the light source and the amount that is received by a detector. Such measurements are affected by the size, shape, and number of particles in a sample of liquid because those solids scatter the incoming light, which provides an apparent absorbance that…

Improved Single-Use Technology for Online Turbidity Measurements

Turbidity is the relative clarity of a liquid as the result of suspended solids. Typically, turbidity measurements are taken by using a beam of light to detect the presence of particles and measuring the difference between the amount of light that is emitted from a source and the amount received by a detector. In bioprocess operations, liquid turbidity often is measured postfiltration to detect “break through,” or undesired materials coming from a filter, which provides an overall assessment of filter…
