  • Publication number: 20190072492
    Abstract: Disclosed herein are methods and systems for analysis of samples. In some cases, the analysis may involve spectroscopic techniques such as Raman spectroscopy. The methods and systems may be used to identify one or more characteristics of a sample, such as the identity of, and the quantity of a molecule within the sample. The methods and systems may be used to determine an impurity of the sample, or inactive excipients within the sample. In some embodiments, the methods and systems of the present disclosure provide for rapid sample analysis that is more accurate, precise and cost-effective than traditional means.
