ID testing of materials in opaque containers can create a bottleneck in pharmaceutical manufacturing. A dedicated sampling area is needed to open, sample, test and re-seal each container to verify the content's identity. The RapID system uses spatially offset Raman spectroscopy (SORS) technology, which is a unique Raman variant ideally suited to noninvasive ID verification of raw materials. The RapID system allows the operator to verify the contents of each container through opaque and colored packaging in seconds, enabling release immediately into production. This saving on handling and lab testing reduces the overhead from hours or days to only minutes per batch.
