Human milk macronutrient analysis using point-of-care near-infrared spectrophotometry

Human Milk Analysis Using Mid-Infrared Spectroscopy.

BACKGROUND The composition of human milk is known to vary with length of gestation, stage of lactation, and other factors. Human milk contains all nutrients required for infant health but requires fortification to meet the needs of low-birth-weight infants. Without a known nutrient profile of the mother's milk or donor milk fed to a baby, the composition of the fortified product is only an esti...

Portable Refrigerant Identification by Near Infrared Spectrophotometry

Nondestructive Firmness Estimation of Tomato Fruit Using Near-Infrared Spectroscopy

Today, nondestructive methods are widely used to determine the quality of agricultural products. Meanwhile, visible and near-infrared (Vis/NIR) spectroscopy is regarded as one of the most widely used methods in the field of quality assessment of agricultural products. In this study, a system was developed to measure the Vis/NIR spectra of tomato fruit samples in the half-transmittance mode of m...

Near-Infrared Spectrophotometry of the Satellites and Rings of Uranus

New spectrophotometry from 1.5 to 2.5 /zm is reported for the Uranian satellites Titania, Oberon, and Umbriel. A spectrum of the rings of Uranus from 2.0 to 2.4/zm is also reported. No evidence is found for frost covering the surface of the ring material, consistent with the low albedo of the rings (P~ = 0.03) previously reported by Nicholson and Jones (1980). The surfaces of the satellites are...

Design of a Near Infrared Spectrophotometry Brain Imaging System

Measuring brain activity is at task generally left for EEG or fMRI. However, there is a lesser known imaging technique known as near infrared spectrophotometry, in which near infrared light is shown into the patients head to measure changes in oxygenation that directly relate to brain activity. This paper describes a low-cost, wireless, portable near infrared spectrophotometry system that is ab...
