The Performance and Testing Department of Ontario Power Generation, Electricity Production Services Division, offers a less common but valuable technique for water flow measurement. Our technique utilizes fluorescent dye and a very precise procedure which provides highly accurate results. The recommended ...
Because of the vulnerability of karst aquifers to contamination and the need for water managers to know recharge areas and groundwater flow characteristics for springs and wells used for public water supply, qualitative and quantitative dye tracing techniques were used during a groundwater investigation...
(1,3-dihydroxybenzene) produced a yellowcompoundhe namedfluorescein, because aqueous solutions show an intense fluorescence. Although not useful as a dye, its value as a marker for accidents at sea and as a tracer of underground water flow is well established. Phthalic anhydride andphenolreact ...
The Determination of PO_4-P in Tannery Wastewaters by Reversed Flow Injection Analysis-phosphorus Antimony Molybdenum Blue Photometric Method A new method for rapid and direct detection of PO4-P in tannery waters is proposed,which is based on phosphorus antimony molybdenum blue photometry.Molybda.....
Dye trace studies were conducted in order to establish subterranean flow routes within the karst system. The first dye trace was conducted by injecting fluorescein dye into the Big Sink, which serves as the presumed drain for the entire cove. The dye reemerged at Buggytop Cave within 50 ...
摘要: The dye dilution curves from twelve human kidneys were compared with systemic curves from the same individuals recorded at the same time. The recirculation distance was the same for both types of recording.关键词: Dye dilution technic renal artery renal artery obstruction ...
Using a continuous flow pilot plant, ozone-loaded Volasil™245 contact was applied to dye-contaminated waters. Process kinetics and efficacy have been assessed in terms of colour, COD and TOC reductions, and also in relation to direct ozone gas contact. Design and operating conditions for the...
In the presence of certain compounds, theglass transition temperature(Tg) of the polymer lowers. They are referred to as plasticising agents. The most familiar plasticising agent forthermoplasticfibres is water, but generally, plasticising agents are more complicated organic compounds. The semi-empiri...
This multiple-exposure image was acquired using bandpass optical filter sets appropriate for DAPI, FITC and Texas Red dye. Additional resources Flow cytometry protocols handbook Protocols that fit your needs in flow cytometry ranging from sample preparation to numerous cell stimulation conditions, ...
Water-soluble BODIPY sulfonated succinimidyl esters The moderate lipophilicity of the BODIPY propionic acid succinimidyl esters discussed above requires their dissolution in an organic solvent before use in conjugations. Although these reactive dyes are very useful f...
