These distinct pharmaceutical waters need to satisfy the quality characteristics as specified in the similar monographs.
“Instrumental” Strategies Examples of instrumental methods involve microscopic Visible counting strategies (e.g., epifluorescence and immunofluorescence) and similar automated laser scanning methods and radiometric, impedometric, and biochemically based methodologies. These methods all possess a range of pros and cons. Pros may very well be their precision and accuracy or their pace of test final result availability as compared with the classical cultural solution.
