OEM Modular Spectrometers for Medical Applications

The application of optical spectroscopy to the monitoring of oxygen in the blood (oxymetry), a non-invasive technique, has now been widely deployed in areas such as operating theatres, emergency wards and intensive care units. The ability to measure blood oxygenation, by observing the absorption of red and near-infrared through a part of a patients body, say foot, finger or earlobe, has empowered medical staff  with the ability to monitor the patients condition through extreme surgical procedures such as brain and heart surgery.  

Optical spectroscopy of skin can yield information about the patient’s welfare, such as grading burns or frozen skin, monitoring transplants or implants, analysing skin diseases or melanomas. In some areas of medicine, the diagnostic technique relies on a specialist, with a trained eye, to evaluate the condition. Now, the optical spectrometer can provide a calibrated tool which can be applied to many conditions and eliminate some of the ambiguity in diagnosing the patient’s state.   In areas of pharmaceutical engineering and medicine, optical spectroscopy has been a powerful tool in developing new drugs, identifying counterfeit drugs, defending patents on medically significant molecules and researching the mechanisms for drug delivery. A spectroscopic technique that observes Raman scattered light, discovered in India in 1928 by Prof C.V. Raman, is now an area of great interest in the biomedical and healthcare market. The Raman technique now has accepted applications in analysing polymorphism in active pharmaceutical ingredients, monitoring the distribution of ingredients in tablets, observing the delivery of drugs at a cellular level. It has been proven to be able to distinguish between different types of cells and could provide a power diagnostic tool for the detection of cancer, micro-organisms and bone disease. If the technique can not probe directly, then enhancement methods, known as surface enhanced Raman scattering (SERS) can be employed to detect specific molecules and diagnose several diseases, in some case simultaneously. The overall application of Raman spectroscopy to the biomedical and healthcare sector is generating a lot of research activity and will be very exciting over the next few years as they begin to proliferate into this market.    

Pacer has a variety of modular spectrometers, based on silicon CCDs and InGaAs arrays. These can be applied to the UV, VIS and NIR region, with parameters that can be modified to suit a specific requirement. The sensitivity and flexibility of these modular spectrometers can be adapted to many techniques in the medical arena, including very low light applications such as Raman spectroscopy.
