Mobofoto: a mobile platform for concentration measurement through colorimetric analysis
Traditional colorimetric measurement is widely used in chemical concentration estimation. However, compared to the laboratory solutions for accurate measurements with professional measuring equipment, colorimetric measurement is often more qualitative than quantitative. It would be most productive …

Development of a Low Cost Handheld Microfluidic Phosphate Colorimeter for Water Quality Analysis
… phosphate colorimeter utilized for water quality analysis. The device can be powered by, and interfaced for data collection with, a common cell phone or laptop to dramatically reduce costs. Unlike commercially available colorimeters, this device does not require the user to measure or mix sample …

Pressurized Hot Water: An Alternative Method of Nutrient Extraction and Subsequent Analysis for Use in Small-Scale Agriculture
Soil analysis for small acreage farms in developing countries is often inconvenient and prohibitively expensive using current procedures, yet the information gained from these soil tests could have economical and environmental benefits. The pressurized hot-water (PHW) extraction coupled with …

The determination of Dyers' perceived components of colour difference (depth, brightness and hue) between twp similar colours from theor spectral reflectance values
… enabling the dyer to take full advantage of colorimetric analysis. The algorithm was based on extensive experimental work to map surfaces of constant visual depth throughout the colour space and the thesis describes the methodology and the necessary calculations to determine the ΔD, ΔB and ΔH …

Development of a rapid screening technique for contaminants in environmental monitoring and regulation
… the water temperature is 20oC. Secondly, digital colorimetric analysis using a flat-bed scanner was utilised to quantify the Cu, Ni, and Co in water following the DGT uptake of metals by Chelex resin gel without involving further reactive reagents. The fully quantitative interpretation of the Cu, …

Effects of Fire on the Nutritional Ecology of Selected Ungulates in the Southern Black Hills, South Dakota
… June-October, 2002 and 2003. Microhistological analysis was used to determine diet composition, and fecal nitrogen and phosphorous were measured using semi-micro Kjeldahl methods and colorimetric analysis, respectively. ANCOVA was used to test for main and interactive effects of year, season, …
