DUNEDIN, Fla., June 12, 2015 — Ocean Optics Inc. has introduced four spectroscopy accessories for dynamic sampling measurements of both solid and liquid samples. The DR Probe integrates a light source and collection optics into one unit to measure 45° diffuse reflectance. It is suited for applications such as color analysis, material identification and quality monitoring of foods. Also available for diffuse reflectance measurements is the DynaCup, a rotating device that presents samples to the DR Probe. The rotation allows the probe to scan the sample multiple times to collect a more consistent, representative spectrum of the sample. This method is important with heterogeneous samples like grains, where variables such as shape, moisture and starch distribution within kernels can vary greatly. The multiplexer accessory is a mechanical actuator that distributes light through ten customizable channels from a single light source. It is useful for any kind of light transmission and optical fiber size. Two models offer a choice between fast positioning or high repeatability and accuracy of performance. The DynaFlux is an integrated transmission and absorbance flow cell for near-infrared and UV-VIS transmissive measurements. DynaFlux accepts standard transmission cells (sold separately) with pathlengths up to 10 mm and a temperature-controlled sampling chamber. A programmable timer allows the flow cell pump to run for fixed times with options for continuous flow to analyze large volumes or stop-flow mode to analyze static samples.
