Automatic sulfur-nitrogen determination instrument

Abstract

The invention discloses an automatic sulfur-nitrogen determination instrument, which includes a sample injector, a cracking furnace, a detector and a computer. The detector is composed of a chemiluminescent detector, an ultraviolet fluorescence detector and a signal amplification circuit. As an improvement, the computer part includes a host computer used for display, storage and data analysis and processing and a lower computer used for control of the sample injector, the cracking furnace and the detector, and the host computer and the lower computer are in communication connection through a USB virtual serial port. With a simple structure, the automatic sulfur-nitrogen determination instrument provided by the invention well solves the problems of weak data analysis and processing ability and low detection precision in existing sulfur-nitrogen determination instruments, and is convenient for popularization and application.

Description

technical field [0001] The invention relates to an electrochemical analysis instrument, in particular to an automatic sulfur and nitrogen measuring instrument. Background technique [0002] Sulfur and nitrogen are the main elements that affect the quality of petroleum, natural gas, chemical raw materials, etc., and are also the main pollutants of the atmosphere. Therefore, it is of great significance to detect the concentration of sulfur and helium. Most of the existing instruments for detecting sulfur concentration use chemical methods, the equipment is complicated, the operation is cumbersome, and they are often interfered by other substances. Therefore, at present, the detection of sulfur dioxide concentration tends to use physical methods, among which the ultraviolet fluorescence method has attracted much attention due to its good selectivity and high sensitivity. The analyzers for the detection of nitrides in my country basically rely on imports, which are expensive a...
