Quantitative determination of water in granites by infra-red analysis
Two methods using nujol and hexachloro-butadiene mulls are described to analyse the water content of powdered granite samples. The nujol mull analyses were carried out on a Unicam SP Ioo spectrometer using the silica content of the rock as an internal standard. The hexachlorobutadiene mull analyses were done by a twin-path Unicam SP 2oo spectrometer, using hexachlorobutadiene as the internal st...
متن کاملRapid Analysis of Cane Juice by near Infra-red
An investigation was carried out to test the suitability of near infra-red reflectance (NIR) for rapidly estimating cane quality components. A large number of mixed cane juice samples of known pol, brix, sucrose, fructose, and glucose content were used to calibrate a Technicon Model 450 InfraAlyzer. Regression analyses indicated that brix, pol, and sucrose values obtained were closely correlate...
متن کاملRapid Analysis of Sugar Products by near Infra
The NIRSystems 6500 spectrophotometer has been used to study analytes in bagasse, shredded cane, direct analysis of cane extracts (DAC), mixed juice, molasses and raw sugar. Analytes included pol, brix, dry solids, moisture, sucrose, glucose, fructose, invert, ethanol, colour, ash and starch. Although Near Infra Red (NIR) is a secondary technique, relying on conventional laboratory procedures f...
متن کاملSterilization of syringes by infra-red radiation.
more, syringes cannot be sterilized assembled or lubricated, and the syringe containers, whether multiple or single, must be so constructed that steam can freely penetrate to all surfaces of the syringe (Stewart, 1957; Darmady and Hughes, 1955). After sterilization a separate process is necessary to seal the containers before distribution to the user. Although syringes in their containers can b...
متن کاملInfra-Red Plasmonic Sensors
Plasmonic sensors exploiting the localized surface plasmon resonance (LSPR) of noble metal nanoparticles are common in the visual spectrum. However, bio-sensors near the infra-red (NIR) windows (600–900 nm and 1000–1400 nm) are of interest, as in these regions the absorption coefficients of water, melanin deoxyglobin, and hemoglobin are all low. The first part of this paper reviews the work tha...
