Drug design and testing of related materials are subject to severe norms and regulation. Fast response analytical techniques are of primary importance.
ELS, provides many solutions for a fast and reliable analysis in the pharmaceutical  industry and research. 

XRF and XRD are a great techniques that can be of primary interest to improve quality, reduce costs and grant health safety and competitive advantages.

X-Ray Diffraction (XRD) , Provides a unique fingerprint of the phase of API’s and very useful for patents!, Confirms phase identification by comparison with pre-existing data, Transformation of phases according to production or storage processes, Distinguishes polymorphs and crystal structure determinations.
X-Ray Fluorescence (XRF), TXRF is an unsurpassed technique for metal contaminant presence (i.e. heavy metals and residual of catalyst).
