Hi, Mui The detector in my in-house NIR spectrometer is a silicon detector. It resposponds to wavelength range from 700nm to 900nm. So I can't tell if the spectra are good or not based on water absorption bands. Jerry Jin | ||

what is the instrument you are using? If you see big fat water band(s) in the area of 970, 1450, 1940 nm, your spectrum is real. Wavelength shift could occur a bit though. If you want, u can send me the spectra of live human tissue as image file or word, so I wont be able to use it at all. Mui | ||

Dear All, I have a in-house NIR spectrometer operating in diffuse reflectance mode. But I have no idea if its measurement is real or not. I want to verify its reflectance measurement by comparing to its commercial counterparts in the market. The sample I am looking into is live human tissue or tissue-simulating solid gel-like phantom. The analyte is hemoglobin. I know there are reflectance NIR spectrometers people use to measure reflectance from fruit or meat. Can anyone let me know the commercial sources and any good recommendation? Best regards. Jerry Jin |
