An apparatus and method for measuring hydrogen peroxide concentration in water to an accuracy of 0.1 ppm comprises a colorimetric assay method to determine hydrogen peroxide concentration. The assay is monitored spectophotometrically at a desired wavelength. Each sample is corrected relative to a ...

Apparatus for accurately measuring the water content of gasAn apparatus for accurately measuring the water content of a moist gas containing less than 50 parts per million (ppm) of water comprises an isothermal heat-sink (14), a radiator (20), a Peltier heater-cooler (24) thermally arranged ...
In this system, one of the key parameter to define thermodynamic equilibria is CO2 solubility. If CO2 solubility in water is rather well documented at temperature higher than 100 °C, measurements at lower temperature and mutual solubility of water in the CO2-rich phase are sparse (Marini, ...
The APHA color scale range is from 0 to 500 in ppm (parts per million) platinum cobalt to distilled water, what is the zero point (also called white water). The test for APHA color is performed in chemical, pharmaceutical, petroleum und plastic industries, as well as in beverage ...
Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water. Measuring the TDS value in the water is to measure the total amount of various organic or inorganic substances dissolved in water, in the unit of ppm or milligra...
A comparative data-reduction exercise showed significant differences in the calculated values of up to 1.7 ppm in xCO2 and 2 μatm in fCO2. After identifying the sources of the differences, the participants agreed upon data collection, quality control and calculation procedures that are presented ...
