Repeat Measurement of a previously analyzed sample is often necessary for a variety of different reasons. The IQ Frame™ can be used to return to the exact same measurement area of a sample on the same instrument for repeat measurement. Reanalyzing a sample allows for further investigation, confirmation of initial findings, the ability to track changes over time or the discovery of additional details that might have been missed in the initial analysis. In addition, advancements in microscopy techniques and equipment may offer higher resolution, improved contrast, or additional imaging modalities. Some applications include reaction and environmental monitoring, degradation studies, stability testing, material characterization, forensic analysis, data reproducibility, method and instrument validation, and long-term research studies, etc.

The combination of data from FTIR and Raman microscopy can provide richer information about structure and chemical composition. IR spectroscopy is useful for the analysis of organic compounds while Raman spectroscopy is useful for the analysis of inorganic compounds and crystal structure because it has a higher spatial resolution compared to IR spectroscopy and can measure down to the low wavenumber region. The combination of data from IR and Raman microscopy can provide richer information about the structure and chemical composition of samples; however, the same minute region must be accurately measured by both methods.
