What are the requirements for the sulfur carbon analyzer test?
Volumetric method (gas content, carbon and sulfur meter): common measuring carbon is gas volumetric method, sulfur measurement is iodine method, acid base titration method. In particular, the gasometric method for measuring carbon iodine determination of sulphur, it is fast and accurate, is the most commonly used method of simultaneous determination of carbon and sulfur in our country, the precision of carbon sulfur analyzer using this method, carbon content limit of 0.050%, sulfur content limit of 0.005%, can meet the needs of the majority of occasions. Determination of carbon and sulfur content in metals, as well as ICP, direct reading spectrometry, X fluorescence spectrometry, mass spectrometry, chromatography, activation analysis, each has its advantages and scope of application. In our country, the most widely used are carbon and sulfur joint measuring instrument, infrared carbon and sulfur analyzer, gas capacity carbon sulfur analyzer, conductivity carbon and sulfur analyzer.
Titration (Di Dingyi): non-aqueous titration system uses acid-base titration for the determination of iron, carbon and sulfur elements. And arc furnace matching, suitable for general laboratory, furnace testing and so on.
Infrared absorption method (infrared carbon and sulfur analyzer): the carbon and sulfur in the sample are heated by the high temperature under the oxygen rich condition to oxidize to carbon dioxide and sulfur dioxide gas. After the gas is treated, it is absorbed into the corresponding absorption cell, absorbed by the corresponding infrared radiation, transmitted by the detector as a signal, and processed by the computer. This method has the characteristics of accurate, rapid, high sensitivity, high and low sulfur content of carbon were used, the infrared carbon sulfur analyzer by using this method, a higher degree of automation, the price is relatively high, suitable for the analysis of precision.
