X-ray diffraction,SEM and nitrogen/oxygen analyzer were adopted for the characterization of the powders obtained under different ammonolysis conditions.
The principle of measuring oxygen concentration by means of Zirconia Detector and the ZOV-2 model Zirconia Oxygen Analyzer controlled by a single chip microcomputer are described in this paper
Using the function for program raising temperature of TC-436 nitrogen oxygen analyzer the oxygen releasing curves of a series of spectra pure oxides,such as Fe 2O 3,MnO 2,NiO,CuO,SiO 2,Al 2O 3,La 2O 3,CeO 2 and other rare earth oxides were studied.
The poisoning phenomenon on the surface of ITO target during DC-Magnetron sputtering process was investigated. XRD, EPMA and LECO oxygen analyzer were used to study the poisoning mechanism and the factors leading to poisoning were analyzed.
This paper briefly introduces the theory of galvanic sensor that is the core of oxygen analyzer. Then,the main factors are analyzed which effect the capillary oxygen sensor. Some advice is offered to use and maintain the oxygen analyzer according to the practice.
The apparatus permits the analysis of the equilibrium gas phase without the collection of samples.2.A magnetoelectric oxygen analyzer, the sensitivity of which in the pressure interval 1-760 mm Hg is ±0.05 mm Hg, was designed and described.
In this paper, we report a new method to investigate the oxygen release process during heat treatment of (Bi,Pb)2Sr2Ca2Cu3Ox (BSCCO) powder, based on oxygen partial pressure measurement (OPPM) using an oxygen analyzer.
The model SY-1 instrument for the determination of dissolved oxygen in seawater is a new type of oxygen analyzer,the design of which is based on a new electroanalytical method-laminar flow chronocoulometry,being designed under the principle with an automatic control requencc,is in highspeed in determination and easy for operation.It can measure the dissolved oxygen in seawater as well as environmental waters with high accuracy.The principal designed requirement are as follows,1.Range...
In this paper a control scheme to save energy for combustion system in IndustrialBoilers is discussed. The whole arrangement, involving an air/fuel oil-ratio controlsystem incorporated with an oxygen analyzer and the steam flow rate device, ispresented here, where the latter is used as a feedforward signal. In order to keepthe oxygen present in the stack gas at an optimum condition, the air/fuel oil-ratiois adjusted by the oxygen controller. The whole scheme will insures complete com...
The studies on the relationships between the output voltage of the Ag-Pb microcell and the content of oxygen and between the output voltage of the cell and the temperature were described. An oxygen analyzer had been designed on the bases of the electrochemical parameters of the cell. The accuracy of the analyzer was ±1% of full scale.
