Since there is an ever constant necessity for the observation and study of low-frequency modes in a system, a Raman spectroscopy system comes as the much-needed solution for a wide range of applications.
The field of spectroscopy is constantly advancing as modern day technology has availed to scientists’ top of the line pieces of equipment which have made studies more extensive. Largely, spectroscopy is all about the analytical techniques used for the study of interactions between electromagnetic radiations and matter. Today, there are lots of methods which can be used to study the molecular vibrations, electronic modes, and nuclear spin orientations that arise from the interactions. Each of the techniques used has its distinct capabilities which make it the go-for choice depending on what is being studied and under what condition.
Nonetheless, there are techniques which have been proven to be more superior over the years and are currently being enhanced by the rapid developments of the spectroscopic instrumentation. One such area is in Raman spectroscopy which is widely used to provide a molecular fingerprint of molecules by relying on the inelastic scattering phenomenon of monochromatic light. While it is not a new technique since it has been around since it was discovered by the Indian physicist Sir C. V. Raman, the developments witnessed over the past years has made it grow exponentially.
These advancements have resulted in the development of major categories of Raman spectroscopy widely implemented in different scenarios. These categories include Surface Enhanced Raman spectroscopy (SERPs), Stimulated Raman Spectroscopy (SRS), Coherent Anti-Stokes Raman Scattering (CARS), Coherent Anti-Stokes Raman Scattering (CARS), and Spontaneous Raman Spectroscopy. Despite the different techniques used for the analysis, they are all united by the fact that a Raman micro-spectrometer allows for the study of extremely small samples without the necessity of physical contacts. This winning attribute has been the primary point of consideration for all scientists who specialize in the niche research field.
The ability to identify different molecules or functional groups from larger molecules has made the practicality of Roman spectroscopy diverse. It is the bonds formed by the particular atoms which bring about the vibrational frequencies that correspond to the atom’s masses and strength that allows for identification using a micro-spectrometer. The result has been an instrument which can be used in several fields of study right from forensics and materials science to pharmaceutical and semiconductor materials research.
It is the massive potentials that a Raman spectroscopy system holds that calls for the need to carefully select the right model that will provide top-grade performance. The line between affordability and functionality is one that can now be easily balanced thanks to the ready availability of advanced models from top of the line manufacturers. A high-quality Raman micro-spectrometer today combines the strengths of microscopy and spectroscopy which make it a ready to use the instrument for various studies. It is critical to ensure that besides having a research grade microscopy system the system can be effortlessly equipped a range of other complementary capabilities. These include an XY motorized stage, multimodality imaging capabilities, and software for ease in chemical mapping.
Another vital consideration that must be made before purchasing a Raman micro-spectrometer is the proven capability of the model in high-end applications. This is because Raman signals are typically very weak which has always necessitated scientists to resort to expensive systems for better accuracies. On the brighter side, this is no longer the rule to abide by as there are economic models which are in-built with great capabilities which ensures excellent reliability. A simple way to discover this is by taking time to analyze the system’s features taking to account the research grade sensitivity, multimodality, functionality wavelength, and Raman mapping options.
In the end, settling for a Raman spectroscopy system that has been tried, tested, and approved eliminates any gambles from the investment one is about to make. An old trick of the book that is still relevant to date is settling for brands and a supplier that is certified and specializes in the niche field of providing research products. This will instantly add intangible value to the entire process of online shopping which has become the norm in the highly digitized generation. It is made better with the assurance of immediate technical support and a team that understands the high demands of day to day spectroscopy research areas.
