Neon isotope
Neon isotope neon isotopes There are three types of neon isotopes – neon 22, neon 20, neon 21, neon isotopes are used in a variety of applications . Ne-22 is used in the production of the medical radioisotope Na-22 . The Ne-20 can be used to produce the F-18 , although the route through the O-18 is by far the most common. Ne-21 has been used in Masers to study quantum physics. isotopeContinue reading “Neon isotope”

About krypton isotopes Krypton 78 krypton 80 krypton 82 krypton 83 krypton 84 Krypton 86
Krypton Isotopes – Krypton was discovered in 1898 by Sir William Ramsay and Morris W. Travers. Its name is derived from the Greek kryptos, which means “hidden”. Krypton is a colorless, odorless, and tasteless gas. It liquefies at -153.22 º C and solidifies at 157.36 º C into a white crystalline substance with a face-centered cubic structure. it Slightly soluble in water. Krypton is a nobleContinue reading “About krypton isotopes Krypton 78 krypton 80 krypton 82 krypton 83 krypton 84 Krypton 86”
Analysis of Uncertainty of Standard Gas Component Value
Gas standard samples and gas standard substances (hereinafter referred to as standard gases), as a physical standard and measurement benchmark, are widely used in scientific research, environmental testing, medical and health, petrochemical, chemical fertilizer, electric power, coal, metallurgy, machinery and other national economies. of various fields. Standard gas has played an extremely important role in calibratingContinue reading “Analysis of Uncertainty of Standard Gas Component Value”
Performance Evaluation of Mixed Gas Standards
1. Inspection of the uniformity of the mixed gas standard sample The degree of uniform mixing of the standard gas will directly affect the accuracy of its component content. For this reason, the prepared standard gas must be homogenized. The prepared steel cylinder was placed on the rolling device and rolled for 2 hours to make itContinue reading “Performance Evaluation of Mixed Gas Standards”
Several basic methods of standard gas waste gas treatment
1. Standard gas waste gas treatment has the following four methods: 1. Adsorption method Adsorption method is also called dry method, which uses solid absorbent to adsorb harmful components in gas. There are many kinds of adsorbents due to the different components of the absorbed gas, such as porous activated carbon, alumina gel, silica gel, diatomaceous earth, etc. Continue reading “Several basic methods of standard gas waste gas treatment”
Weighing method is the classic method of standard gas preparation
Weighing method is a classic method for international and domestic standard gas preparation. In the past, a precision mechanical balance was usually used as a preparation tool for standard gas, and a set of relatively mature methods for the evaluation and calculation of uncertainty in the weighing process of the balance has also been established. In recentContinue reading “Weighing method is the classic method of standard gas preparation”
Standard gas distribution method
There are three methods of standard gas distribution: 1. Syringe gas distribution method When only a small amount of standard gas is required, a 100ML syringe can be used to prepare the standard gas; the required low-concentration standard gas can be obtained after multiple dilutions. The concentration of the standard gas can be calculated according to theContinue reading “Standard gas distribution method”
Static distribution and characteristics of standard gas
In air and waste gas monitoring in environmental monitoring, standard gases are as important as standard solutions and standard substances, and are the basis for testing and testing methods, evaluating sampling efficiency, drawing standard curves, calibrating analytical instruments and conducting testing quality control. The method of preparing low-concentration standard gas is usually divided into: static gas distribution methodContinue reading “Static distribution and characteristics of standard gas”
