Component Analysis and Standardless Quantitative Analysis for Pharmaceutical Applications

Traditional quantitative analysis of solid form content in a solid sample is challenging. Most notably in the production of representative standard calibration samples covering the concentration range of interest. In addition to weighing, mixing and homogeneity errors, the resulting boutique standards will likely be not representative of the unknown material being analyzed.

The ideal solution has always been a Standardless Quantitative approach that is representative and relevant to the materials being studied. Component analysis using equal area scaling can make this ideal quantitative analysis solution a reality.

Simultaneous XRD-DSC - The Sum is Much Greater Than the Parts

Almost all analytical labs supporting the Pharmaceutical industry will have both Thermal analysis tools and X-ray powder diffraction. So, what is the benefit of combining simultaneous DSC and XRD measurements into a single attachment. It turns out that having the simultaneous thermal and powder data on the same sample yields a wealth of information that is often not easily accessible using each analytical technique separately. In addition to a discussion on the system itself, some of the benefits that will be introduced include:

The DSC – XRD data are collected on the same sample at the same time so unusual thermal events can be directly associated with a powder pattern to assess any structural changes, and conversely, unusual changes in the powder pattern can be associated with a thermal trace to determine if the changes are truly structural (polymorphic) or just preferred orientation or ripening.
Broad thermal events like re-crystallization can contain multiple transitions through various metastable polymorphs. Using the thermal trace as a guide, more detailed XRD scans can be performed to tease out metastable polymorph structure and powder pattern fingerprints. This can be a rapid screening approach for novel solid forms.
The XRD-DSC unit also has controlled humidity which can be used to quickly bracket stability and storage conditions for APIs, intermediates, and drug products. In addition to opening a huge playground of thermodynamic conditions for solid form investigation.
