Determination of wavelength candidates for non-invasive hemoglobin measurement devices and energy spectrum analysis

Abstract

Hemoglobin (Hb) is an important parameter in human medical treatment. At present, hemoglobin level is measured by invasive method. This method require blood sample, less accurate and the result can be delayed. So that, human hemoglobin spectrophotometry characterization research to obtain a spectrophotometric spectrum in the development of non-invasive hemoglobin measuring devices is needed. The advantages of non-invasive method are do not require blood samples, high accuracy, painless, and allow for quick. Hemoglobin level measurement in non-invasive method can be done by measuring light absorption at different wavelengths. This non-invasive device needs appropriate LED wavelength to detect the level of hemoglobin. Hemoglobin is the dominant absorbent at 800-1600 nm. This experiment used near infrared (NIR) spectrum analysis in 1000-2500 nm. The result of this experiment is the candidates for LED wavelength that can be used in non-invasive hemoglobin measurement devices are 1200 nm and 1300 nm. This determination is based on the lowest standard deviation value at 1293 nm, the highest correlation value at a wavelength of 1266 nm, and is in the near infrared region vibration of C-H functional group at the 3rd energy level, 1252 nm in harmonic vibration. At a wavelength of 1200 nm and 1300 nm it shows low infrared absorption. It shows that non-invasive hemoglobin measuring devices that use an infrared reflectance sensor can be used.Hemoglobin (Hb) is an important parameter in human medical treatment.
