Abstract
The fast progress in miniaturization of near infrared (NIR) spectrometer has taken advantage of
technologies. We have developed a new technology enable of analyzing blood without blood – Progenos® instrument.
Progenos® use NIR spectroscopy and chemometric algorithms to non – invasive blood analysis and is a portable instrument. In order to investigation the Progenos® effectiveness, we presents in this paper a comparison study between Progenos® and VIAVI MicroNIR®, a commercial equipment.
These two equipment analyzed the same samples of a binary mixture containing white aluminum oxide and activated carbon and the data treated by chemometrics. Our study presented here showed that analytical results obtained with Progenos are the same as those obtained with the VIAVI MicroNIR® instrument. Therefore, Progenos® has all the necessary technologies and innovation to application in biochemical analyses.
Introduction
The fast progress in miniaturization of near infrared (NIR) spectrometer has taken advantage of new technologies and has to led a drastic reduction of spectrometer size and weight while allowing good performance due to the high precision implementation of important elements in the final device [1-2].
Blood analysis normally used in nowadays is costly, slow and brings discomfort to patients. Some papers describe non –invasive methods for analyzing blood using various techniques [3-6]. Nevertheless, the use of NIR spectroscopy associated with chemometrics deserves special mention for use as a non – invasive blood analytical method in humans [7].
Our company developed a new portable instrument, Progenos®, based in NIR spectroscopy and using chemometric algorithms to performed blood analysis without blood [8-9]. Based too in NIR spectroscopy, VIAVI MicroNIR® is a commercial equipment that has technological components originally developed for National Aeronautics and Space Administration (NASA) interplanetary spacecraft [10].
In order to investigation the Progenos® effectiveness, we present in this paper a comparison study between Progenos®
and VIAVI MicroNIR®.
