The advancement of analytical methods and systems are paving the way for innovation in academic, industrial and government sectors. As a result of the fast-paced progress, more research questions are asked that surpass the limits of these technologies. The mIRage IR Microscope is now answering these questions using Optical Photothermal IR (O-PTIR) spectroscopy, as well as IR+Raman – simultaneous submicron IR and Raman microscopy. With more chemical characterization requirements being met, mIRage is ushering in the next generation of applications and technology developments in numerous industries.

Film defect identification
Polymers are present in virtually all products we interact with daily. With increasing environmental awareness, polymer science is looking at more novel and complex solutions to improve functionality and reduce environmental impact. These requirements often exceed the limits of traditional IR microscopy, especially when it comes to spatial resolution. The mIRage IR Microscope, with its unique submicron spatial resolution using a non-contact reflection mode technique, is able to meet even the most demanding of analytical and sample characterization needs.

Submicron IR+Raman Microplastics
mIRage locates PS and PMMA beads in salt crystal mixture (difficult to tradition FTIR microscope) in hi-res IR images at key absorption bands
Distortion free spectra at hotspots confirm the identity of the microplastics and readily searched against IR database

O-PTIR Scan of Bioplastic Laminate
Linear sampling scan spanning 8.0µm measured every 100µm apart (plotted only every 200 nm and across 2 mm for clarity) across the boundary of the bioplastic laminate, moving from the pure PHBHx layer to the pure PLA layer.
Gradual spectral changes over the space much greater than the optical resolution suggest the mixed distribution of PLA and PHBHx without any sharp boundary.
No clear isosbestic point indicates that the system is not a simple binary mixture.
PLA and PHBHx contributions are overlapped and mingled in the fingerprint region

Pharmaceutical analysis often requires very precise and accurate measurements. With often tightening regulatory standards, development of new analytical methods must correlate. With unique submicron spatial chemical resolution, combined with simultaneous IR and Raman microscopy (IR+Raman), the mIRage IR Microscope is uniquely placed to meet and exceed the analytical needs of the pharmaceutical industry, across applications areas such as failure analysis, subvisibles and API/Excipient distribution in solid dose or emulsion-based formulations.
