Handheld Raman spectrometers have fundamentally changed how the pharmaceutical industry performs incoming raw material identification.
Micro volume measurements take place at very small pathlengths, typically ≤ 1 mm. Reducing the pathlength has the same effect as diluting the sample for measurement in a conventional instrument. This allows you to save on the sample amount used for UV/VIS spectrophotometry.
Subvisible particulate testing is critical to assess the safety of medical devices, and particulate contamination should be minimized to avoid possible negative health consequences to the patient.
