The first part of this article introduced the basic features of Raman spectroscopy and presented some examples of its application in the pharmaceutical industry. This second part focusses on the technique's application as a PAT tool within the pharmaceutical manufacturing environment. FDA's PAT initiative has provided motivation to explore the application of 'new' analytical technologies to the pharmaceutical manufacturing process and Raman spectroscopy shows great promise. The strengths and weaknesses of the technique as a potential PAT tool are discussed together with some examples of how this works in practice in a pharmaceutical manufacturing environment.

This article describes the quality of highly purified water and its applications, addressing why ultrafiltration (UF) is being used as a downstream purification process. It aims to show that UV is a real alternative for producing pyrogen-free water. This method allows essential cost savings compared with distillation and guarantees a higher safety than other membrane methods such as reverse osmosis.

Ultrafiltration is a pressure-driven membrane filtering process used to separate and/or purify dissolved or suspended particles from water and other liquids. Recent advances in materials and membrane manufacturing techniques have led to ultrafiltration playing a pivotal role in a number of biopharmaceutical processes, including protein concentration and blood for actionation. This article examines the criteria that should be considered when selecting membranes for such applications.
