Sub-500nm Simultaneous IR+Raman Microscopy for Microplastics and Materials Science Research

DATE

February 8, 2023

TIME

8:00 a.m. PST / 11:00 a.m. EST / 16:00 GMT / 17:00 CET - Duration: 60 Minutes

Overview

IR and Raman spectroscopy are well established, mature techniques present nowadays in most analytical laboratories. However, they do pose several key fundamental limitations. The new breakthrough technique of Sub-micron Optical Photothermal Infrared (O-PTIR) Spectroscopy overcomes the limited spatial resolution of traditional IR microscopy with submicron resolution and the limited sensitivity and fluorescence interference limitations of Raman microscopy.

Furthermore, O-PTIR is able to bring together the complementarity of IR and Raman into a single platform, single measurement for the first time, enables sub-micron, simultaneous IR+Raman microscopy delivering IR and Raman spectra from the same spot, at the same time with the same spatial resolution.

This webinar discusses this novel technique and provides numerous application examples.

Part 1: Introduction & Overview by Dr. Mustafa Kansiz

Overview of current direct IR (FTIR & QCL) and Raman micro spectroscopic techniques and Fluorescence Microscopy
Introduction to Submicron O-PTIR and simultaneous Raman microscopy (IR+Raman) and the benefits of co-located Fluorescence
Various application examples of particulates, materials science and more

Part 2: Review of Environmental Applications by Dr. Andrew Ault Microplastics, environmental

Dr. Ault will present the results of his group's recent publication on an important source of atmospheric particles - Sea Spray Aerosols (SSA).

In this work, they characterize individual SSA particles using new generation submicron simultaneous IR+Raman (O-PTIR) microscopy for organic profiling, combined with EDX for elemental profiling.

Dr. Ault will also talk to his recent research relating to microplastics.
