This specification does not apply to the use of infrared analysis principle of carbon and sulfur analyzer, and total sulfur in coal analyzer calibration.2 OverviewDetermination of carbon (the C), the type of instrument hydrogen (H), nitrogen (the N), oxygen (O), sulfur (S) element number, basic The measurement principle is the presence of a catalyst (oxidant) in the presence of (hot) conditions, the samples of the measured elements oxidize Respective gas, based on the physical and chemical properties of the generated gas, select the appropriate analytical methods to detect. Commonly used detection side Law infrared, thermal conductivity method, titration, absorption, power law (also known as Coulomb's law) and the like. Kjeldahl instrument is the proteins in the sample is decomposed under catalytic heating, combine ammonia with sulfuric acid to produce raw Into ammonium sulfate, and then distilled ammonia free alkaline, with boric acid absorption in sulfuric or hydrochloric acid standard titration solution titration, root According to the acid consumption is multiplied by the conversion factor, is the protein content. Carbon (C), hydrogen (H), nitrogen (N), oxygen (O), sulfur (S) element analyzer (hereinafter referred to as equipment) generally By the host control system, an integral part of the detection system, a data processing system, in addition comes with sample preparation, weighing (points Analytical balances) and other equipment (Figure 1).
