Pittcon 2024: Novel Spectroscopic Techniques
On Tuesday February 27, a Pittcon oral session, titled “Novel Spectroscopic Techniques,” took place at the San Diego Convention Center in San Diego, California. This session featured three talks that covers spectroscopic applications across various fields.
The first talk is titled “Low Water Analysis Reimagined: Instant NIR Measurements for Quality Control & Process Upgrades,” and was delivered by Elena Hagemann a product manager. from Metrohm. Haagemann’s talk focused on water analysis, detailing how using near infrared (NIR) spectroscopy requires calibration efforts, and how auto-building prediction models down can help save time by removing the calibration efforts from the process.
Next, Tobias Gokus of Attocube Systems delivered a talk titled, “Infrared Correlation Nanoscopy with Unprecedented Spectral Coverage.” Gokus’s spoke about a recent study that was conducted on how scattering-type scanning near-field optical microscopy (s-SNOM) and tapping AFM-IR+ imaging and spectroscopy based on a fully integrated, automated OPO laser can cover the spectral range from 1.5–18.2 µm (7100–540 cm-1) with a narrow linewidth of <4 cm-1 in the entire spectral range.
Jaakko Lehtinen of Gasera closed out the session with a discussion on “PFC leak detection in semiconductor cleanrooms using photoacoustic spectroscopy.” Lehtinen’s lectured focused on monitoring perfluorocarbons (PFCs) levels using a new gas monitor, called Gasera One PFC, that can directly monitor different kinds of PFCs at very low levels.
Exoplanet Discovery Using Spectroscopy
March 26th 2025Recent advancements in exoplanet detection, including high-resolution spectroscopy, adaptive optics, and artificial intelligence (AI)-driven data analysis, are significantly improving our ability to identify and study distant planets. These developments mark a turning point in the search for habitable worlds beyond our solar system.
Using Spectroscopy to Reveal the Secrets of Space
March 25th 2025Scientists are using advanced spectroscopic techniques to probe the universe, uncovering vital insights about celestial objects. A new study by Diriba Gonfa Tolasa of Assosa University, Ethiopia, highlights how atomic and molecular physics contribute to astrophysical discoveries, shaping our understanding of stars, galaxies, and even the possibility of extraterrestrial life.
New Telescope Technique Expands Exoplanet Atmosphere Spectroscopic Studies
March 24th 2025Astronomers have made a significant leap in the study of exoplanet atmospheres with a new ground-based spectroscopic technique that rivals space-based observations in precision. Using the Exoplanet Transmission Spectroscopy Imager (ETSI) at McDonald Observatory in Texas, researchers have analyzed 21 exoplanet atmospheres, demonstrating that ground-based telescopes can now provide cost-effective reconnaissance for future high-precision studies with facilities like the James Webb Space Telescope (JWST) (1-3).
