Process Analytical Technology

Abstract

The increasing demand for the better healthcare products has changed the pharmaceutical industry. In the recent
years, the technologies producing the quality products have paved the way for good quality products. The
introduction of new tools and technologies has provided an opportunity for the pharmaceutical producers to
improve the quality standards of the product. PAT is one of the technologies in pharmaceutical production
where they test out the quality of the raw materials, characterize them both physically and chemically, through
at-line, in-line or on-line. PAT saves time and money required for testing and analyzing the products. The PAT
paves the way for making good quality products thus satisfies the customers needs and build a good brand
image for the organization. The two effective tools NIR and RAMAN spectroscopy are used in testing the
quality of the products. This research essay delves the essentials of PAT and the usefulness of process analyzers
in process monitoring. The effectiveness of the PAT tools and the advantages of NIR over RAMAN
spectroscopy are clearly discussed.
