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.

How Analytical Chemists Are Navigating DOGE-Driven Funding Cuts
July 14th 2025DOGE-related federal funding cuts have sharply reduced salaries, lab budgets, and graduate support in academia. Researchers view the politically driven shifts in priorities as part of recurring systemic issues in U.S. science funding during administrative transitions. The impact on Federal laboratories has varied, with some seeing immediate effects and others experiencing more gradual effects. In general, there is rising uncertainty over future appropriations. Sustainable recovery may require structural reforms, leaner administration, and stronger industry-academia collaboration. New commentary underscores similar challenges, noting scaled-back graduate admissions, spending freezes, and a pervasive sense of overwhelming stress among faculty, students, and staff. This article addresses these issues for the analytical chemistry community.
Drone-Mounted Infrared Camera Sees Invisible Methane Leaks in Real Time
July 9th 2025Researchers in Scotland have developed a drone-mounted infrared imaging system that can detect and map methane gas leaks in real time from up to 13.6 meters away. The innovative approach combines laser spectroscopy with infrared imaging, offering a safer and more efficient tool for monitoring pipeline leaks and greenhouse gas emissions.
How Spectroscopy Drones Are Detecting Hidden Crop Threats in China’s Soybean Fields
