VUV Analytics

Analysis of Residual Solvents in Pharmaceutical Excipients and Products with Static Headspace – Gas Chromatography – Vacuum Ultraviolet Absorbance Spectroscopy

Lindsey Shear-Laude describes how residual solvents determination in pharmaceutical products by GC-VUV and automated headspace sampling results in >5X shorter chromatography runtimes and allows the combination of multiple solvents (Class 1, 2, and others) into a single analysis.

View the follow-up webinar hosted by GERSTEL to get additional details about the analytical solution provided when GC-VUV is combined with the GERSTEL automated headspace Multi-Purpose Sampler (MPS).

“The VUV detector has proven itself with the ability to distinguish olefins and aromatics from aliphatics – that’s a killer application given the complexity and time involved using any other technique. The VUV detector’s ability to perform a more accurate and much more robust PIONA analysis is an important milestone in its ongoing success.”

“One of the main advantages of VUV detection for us appeared to be the ability to gain more specific molecular information…co-elutions that we know exist but cannot be identified with FID can be unraveled.”

“One thing that I really like about VUV is that it can be considered a universal detector but with the advantage of being familiar to us. We all used UV spectrometers in school.”
