DFY—12型定碳定硫自动分析仪是用电导法分析金属中的碳和硫含量的仪器。我们经一些改进后,应用于催化剂的积炭量的测定。 基本原理 电介质溶液电导的大小与导体的截面积A成正比,而与其长度Ⅰ成反比: L=k(A/1) 式中,k是比例常数,称为该物质的电导率。对电解质而言,取面积为1厘米~2的两个电极,两极间距离为1厘米,中间放置1厘米~3溶液时所表现出来的电导称为该溶液的电导率,对一定的电解质溶液,电导率决定于温度、浓度、压力等因素。
DFY-12 fixed carbon sulfur analyzer is the use of conductivity analysis of metals in the carbon and sulfur content of the instrument. We have some improvements, the catalyst used in the determination of the amount of carbon deposition. Fundamentals The magnitude of the conductivity of a dielectric solution is proportional to the cross-sectional area A of the conductor and inversely proportional to its length I: L = k (A / 1) where k is the proportional constant and is called the conductivity of the material. For the electrolyte, take an area of 1 cm ~ 2 of the two electrodes, the distance between the two electrodes is 1 cm, the middle placed 1 cm ~ 3 solution when the conductivity is expressed as the conductivity of the solution, a certain electrolyte solution Conductivity depends on the temperature, concentration, pressure and other factors.
