Part 1: Introduction to O-PTIR

• Overview of current direct IR (FTIR & QCL) and Raman microspectroscopic techniques applied to MPs
• Recognizing and understanding spectral artefacts/inconsistencies and how they significantly reduce MP ID accuracy
• Introduction to featurefindIR™ software automation and reporting for Submicron O-PTIR and Simultaneous Raman microscopy
• How cross-polarized visible light microscopy can be used to enhance particle detection
• Combined fluorescence (Nile Red) imaging for polymer particle locating (amongst inorganics), followed by O-PTIR analysis for increased efficiency and time savings
• See examples applied to MPs and microfibers from <500nm to mm’s and how the spectra are reliable and reproducible, regardless of particle shape and size

Part 2: Live demo

• See, in real-time, how easy it is to use featurefindIR™ for MP analysis in seconds, ranging from <500nm to mm’s and immediately search spectral databases and generate reports with key particle shape/size information together with chemical identification.
• The webinar will be recorded for later on-demand viewing with opportunities to ask questions during and after the webinar.

Part 1: Webinar will cover;

• Overview of different IR and Raman spectroscopic techniques applied to MPs
• Recognizing and understanding spectral artefacts/inconsistencies and how they impact accurate MP identification
• Introduction to Submicron O-PTIR and Simultaneous Raman microscopy
• How to eliminate these spectral artefacts/inconsistencies for accurate MP identification with O-PTIR
• Complementary and confirmatory simultaneous IR+Raman spectral collection and spectral searching for improved identification accuracy
  See examples applied to MPs from <500nm to mm’s and how the spectra are reliable and consistent (no artefacts)

Part 2: Live demo:

• See, in real-time, how easy it is to collect submicron IR and Simultaneous Raman data from MPs, ranging from hundreds of microns to <500nm

Join Dr Mustafa Kansiz, the director of product management and marketing for Photothermal Spectroscopy Corp, in this two part event. In the first part view a webinar on how to conduct robust, reliable and accurate MPs analysis of small (<500nm) to large (mm’s) MPs on the one instrument without encountering any of pitfalls, challenges and artefacts seen with traditional direct FTIR/QCL and Raman microscopy.
In the second part watch, in real-time, a demonstration of submicron O-PTIR and simultaneous Raman microscopy being used to generate consistent and artefact free spectra of MPs <500nm to the very large (mm’s), regardless of particle shape and size.

Particle analysis with submicron IR spectroscopy and simultaneous Raman – Microplastics, fibers and atmospheric aerosols

Available for viewing

Asst. Prof. Andrew Ault and co-workers demonstrate the novel application of submicron IR and simultaneous Raman for the physiochemical analysis of atmospheric aerosols with aerodynamic diameters <400nm. Vibrational spectroscopy (IR and Raman) has great potential for atmospheric aerosol characterization, but the diffraction limit of traditional IR microscopy (~10 microns) makes this impossible. In their recent publication, the team has shown for the first time, how Optical-Photothermal IR (O-PTIR) spectroscopy can be used for non-contact, far-field submicron particle measurements to yield high spectral spectra that are easily searchable and interpretable. Furthermore, they demonstrate how combining this analysis with simultaneous Raman provide for a more thorough chemical characterisation of the atmospheric aerosols, proving a rich information on their organic and inorganic composition.
In conjunction with Dr Mustafa Kansiz, Director of Product Management at PSC we are proud to present this cutting edge webinar.

Bioplastics characterization – Polymer applications using sub-micron simultaneous IR+Raman spectroscopy

Available for viewing

Dr. Isao Noda and co-workers explore the spatial chemical distributions at the interface of a bioplastic (PHA/PLA) laminate at previously unattained levels of spatial resolution of a few hundred nm, Using O-PTIR coupled with Raman (IR+Raman), new insights at the interfacial boundary of PHA and PLA are reveal. Previously thought to be immiscible, using 2-D Correlation Spectroscopy (2DCOS) data analysis, a surprising degree of polymer mixing together with decreased crystallinity at the interface is revealed, thus potentially explaining the high compatibility of this two bioplastics.
In conjunction with Dr Curtis Marcott, who will introduce the breakthrough technique of O-PTIR and through discussion of a range of polymer application examples, will illustrate the advantages of O-PTIR.
