[Temperature effect on the noninvasive measurement of human blood glucose by NIR].

During the noninvasive measurements of body blood glucose, the result will be effected by many factors, such as the measuring conditions including temperature, contact pressure and so on, and in addition the change of body's state also will induce some error. However, among so many factors the temperature is very important and should be discussed. To find the quantitative value of the result bias caused by temperature in the wavelength range from 1 100 to 1 700 nm, the aqueous glucose with the concentration ranging from 10 mg x dL(-1) to 200 mg x dL(-1) and 10 mg x dL(-1) interval was detected at temperature of 15, 20, 25, 30, 35 and 40 degrees C.

[Fast outlier detection for milk near-infrared spectroscopy analysis].

Near-infrared spectroscopy is a fast and efficient analytical technique based on multivariate calibration model, which correlates near-infrared spectra with the property of samples (such as concentration). The reliability of analytical results depends mostly on the accuracy of measured spectra. But outliers do not make for reliable data.
