operating software

：

Compiled using Deliph software and operated entirely in Chinese for Windows XP.

analysis channel

：

Provide channel management function, carbon and sulfur channels can be added, deleted, and edited independently without any quantity limit.

Analysis function

：

analysis processDynamic data integration and 20 samples per second have improved the sensitivity and accuracy of analysis;

Provide sample management function, which allows editing of sample names and labels, as well as adding and deleting sample names;

The software provides a multi-user management system, which allows administrators to set different user permissions.

display function

：

One curve box for carbon and sulfur,Dynamically display real-time data and carbon and sulfur release curves during the analysis process.

Data processing function

：

The analysis results are stored in the ACCESS database, which can store all the data and curves of carbon and sulfur analysis for each time;

The analysis results can be freely queried based on various factors such as time, operator, sample name, and identification;

Provide multiple functions such as curve/data storage, blank deduction, parameter setting, channel selection, mathematical statistics, result correction, curve comparison, etc;

The generation and curve fitting of carbon sulfur working curves can be achieved in software.
