CONSTITUTION: A device for simultaneously monitoring corrosion and determining the end point of chemical cleaning processes of a power plant boiler by hydrogen gas comprises a reactor(13), a nitrogen purge device(14), a flow rate controller(15), a cooling device(16) and a hydrogen gas sensor(...
1) end point of potentiometric titration 电位滴定终点1. used second derivative method to determine an end point of potentiometric titration,the effects of titration accuracy to strong acid bases and weak ones were theoretically analyzed. 从理论上分析了二级微商法确定电位滴定终点对强酸碱、弱酸碱准确度...
The method of end-point detection described is very sensitive. In titrations with sodium sulphide, the first drop of titrant in excess cause evolution of hydrogen sulphide which acts as a catalyst for the indicating iodine—azide reaction. The gas formed at the end-point is transferred by a ...
In this study, the control of the transfer from holding to screw recovery, that is the control of the end-point of the holding phase, was examined. The holding end-point control by time, cavity pressure and cavity temperature were presented. The purpose of this study was to validate the ...
RNA-DNA Chimeras in the Context of an RNA World Transition to an RNA/DNA World The RNA world hypothesis posits that DNA and proteins were later inventions of early life, or the chemistry that gave rise to life. Most scenarios put fort......
