VUV spectroscopy provides a method for residual solvent characterization that results in reduction of chromatography runtimes by 5X or greater. In addition, different solvent types (Classes 1–3 and others) can be combined into individual compressed analyses for further sample throughput gains. Water determination by GC-VUV delivers a more accurate and precise method than Karl Fischer while not requiring the use toxic reagents.
Known advantages of VUV Spectroscopy
- The ability to compress chromatography runtimes by 5X or greater
- The capability of combining different solvent classes and types (Class 1–3 and others of interest) into individual compressed analyses.
- GC-VUV offers a more precise and user friendly method for water determination
- Co-eluting impurities including isomers can be analyzed without need the for chromatographic baseline resolution
- Instrumentation and software is designed for scaling from R&D to production
- Intuitive data processing workflow and software automation remove analytical complexity

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.
Register for the follow-up webinar on August 24th at 2 pm EST 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).
Shining a new light in gas chromatography and streaming gas applications.
Everything absorbs strongly in the VUV spectrum. Compounds can be unambiguously identified and quantitated in a variety of applications including oil & gas, forensics, fragrances & flavors, petrochemical, environmental, and life science. VUV detectors provide unmatched selectivity of isomers and co-eluting analytes without the need for chromatographic baseline resolution. Unlike legacy detection methods, VUV spectroscopy allows for more automated analysis with lower risk of errors, shorter chromatography run times, and higher analytical throughput.
- Universal, yet selective detector with very sensitive spectral response
- Easy deconvolution and quantitation of co‑eluting analytes
- Robust technology with no reliance on vacuum pumps
- No calibration required – 1st principle detection technique provides a predictable linear response
- A non-destructive technique that compliments mass spectrometry

A New Method for Fast Residual Solvents Analysis and Untargeted Unknown Identification Faster Sample Throughput and Shorter GC Runtimes Using GC-VUV and Static Headspace
Volatile organic compounds are used in pharmaceutical manufacturing during the production of drug substances, pharmaceutical additives, and drug products. Known also as residual solvents, they account for 50-90% of mass in typical pharmaceutical operations and represent most of the process toxicity. These organic solvents can contaminate the drug product during its packaging, storage, and transportation....

Finding VUV’s “Killer Application”Cary Anne Simpson
Cary Anne Simpson
Earlier this year my general practitioner measured my height at my regular check-up. What-the-heck? I’m used to my kids standing under the ruler annually, but I haven’t done that in…well, never mind. It doesn’t matter how long it has been since I stopped growing. I, of course, asked why I was being measured and was...
“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.”
