Total Organic Carbon Analyzer For ISS

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">On the International Space Station (ISS), atmospheric humidity condensate and other waste waters will be recycled and treated to produce potable water for use by the crews. Space Station requirements include an on-orbit capability for real-time monitoring of key water quality parameters, such as total organic ...

Total organic carbon removal instrumentation

Filtration + Separation, 2018
Organic compounds in water can indicate a failure in filtration and storage. Total organic carbon (TOC) instrumentation is used to analyse water and identify organic components. We discuss TOC in the wastewater industry and the type of instrumentation and methods employed.

Determining biomass from differential total organic carbon

Biotechnology Techniques, 1997
A simple procedure for the determination of biomass concentration based on total organic carbon (TOC) is presented. The method uses a total of 2mL of sample, and requires less than an hour to perform. The technique is accurate to 0.009g/L biomass. Samples can be refrigerated at 4°C without affecting readings. Other characteristics are well within those

Miniature Total Organic Carbon Analyzer: Early Development

42nd International Conference on Environmental Systems, 2012
Currently, the International Space Station recovers potable water from a majority of the wastewater sources. Future human exploration missions will also require “closing the water loop” to a high degree because of the expense of resupply and diminishing proximity to Earth.

Photocatalytic oxidation for total organic carbon analysis

Analytica Chimica Acta, 1990
Abstract A new method and apparatus for the determination of organic carbon in water are described. Photocatalytic oxidation of organic matter by near-UV illuminated titanium dioxide is used to convert organic carbon to carbon dioxide. Atmospheric oxygen is the oxidant. The light source is a 20-W black-light fluorescent tube.

Total Organic Carbon and Carbon Isotopes of Sediments

1981
This research project addresses the question: do the isotopes of carbon in the organic matter of the sediments within and around the Buccaneer Field indicate that any alteration of the sedimentary organic matter has resulted from drilling and producing operations?

Determination of protein concentration by total organic carbon analysis

Journal of Biochemical and Biophysical Methods, 1991
Determination of the carbon concentration in protein solutions by total organic carbon analysis was found to be a sensitive and reliable method for the estimation of protein concentrations. Using a carbon content of 0.53 g/g in protein and of 0.44 g/g in carbohydrate, the concentrations of normal proteins, proteins containing chromophoric groups, and ...

Total soil organic carbon and carbon sequestration potential in Nigeria

Geoderma, 2016
Abstract This study aimed to quantify SOC stocks and potential C sequestration for Nigeria using legacy soil data. Mass preserving splines were fitted to legacy SOC and bulk density (BD) pedon data based on GlobalSoilmap soil depths. SOC concentrations (g kg −1 ) were predicted using Random Forest model (RFM), Cubist and Boosted regression tree (BRT).
