Webinar overview
Raman microscopy is widely used for chemical identification and chemical imaging, yet many real-world organic samples remain difficult to analyze with Raman. Biological tissues, cells, and environmental microplastic samples often exhibit strong fluorescence backgrounds, while weak scattering limits sensitivity. This can lead to researchers frequently encountering long acquisition times, uncertain particle identification, or datasets that lack the quality needed for confident interpretation and identification.
Infrared spectroscopy is a powerful technique for chemical identification of organic samples but it has poor spatial resolution compared to Raman, tied to its much larger wavelengths. This webinar will discuss a breakthrough new sub-500nm IR spectroscopy technique called Optical photothermal IR spectroscopy (O-PTIR). O-PTIR provides chemical imaging and spectroscopy without fluorescence interference in seconds on organic samples such as microplastics and life sciences.
This webinar will also discuss examples of simultaneous sub-micron IR and Raman spectroscopy, from the same sample region, such that the complementarity of IR and Raman without fluorescence interference in seconds as well as new laser-scanning based innovations for high-speed imaging for improved throughput. Application examples in microplastics characterization and life science research will demonstrate how challenging samples can be analyzed more reliably, how chemical specificity can be improved, and how multimodal workflows can provide actionable chemical information where traditional Raman imaging struggles.
