GSWK-2F Microcoulometric Comprehensive Analyzer for Sulfur and Chlorine Analysis

Product Overview
The GSWK-2F Microcoulometric Comprehensive Analyzer is an upgraded microcoulometric analysis instrument developed from the WK-2E series. It provides improved detection limits, repeatability, stability, and reliability in a more compact instrument design.
The analyzer supports liquid, gas, and solid sample analysis through different optional sample injectors and is particularly suitable for sulfur and chlorine determination in petroleum, chemical, metallurgical, and research applications. Automatic sample injection and computer-controlled analysis help simplify routine testing and improve laboratory efficiency.

Key Features
• Improved detection limits and repeatability compared with the previous WK-2E model.
• Supports analysis of liquid, gas, and solid samples with optional sample injectors.
• Sulfur detection limit down to 0.05 mg/L and chlorine detection limit down to 0.1 mg/L for liquid samples.
• Supports automatic liquid sample injection and automatic analysis initiation from either the computer or injector.
• Adjustable process parameters for analysis of different or challenging sample types.
• Windows-based Chinese/English software with historical data and curve playback for comparative analysis.
• USB interface, Access database, and LIMS connectivity for data management and laboratory integration.
• Compact design with temperature control from room temperature to 1100°C.

Working Principle
The GSWK-2F uses microcoulometric analysis to determine the concentration of target components based on the amount of electricity required for an electrochemical reaction.
During analysis, the sample is introduced into the system through an appropriate liquid, gas, or solid sample injector. Target components such as sulfur or chlorine are converted into electrochemically detectable species in the reaction system. The instrument measures the corresponding electrochemical response and calculates the analyte concentration from the electrical charge consumed during the reaction.
The computer-controlled system can automatically manage sample injection, analysis, data processing, and historical data storage, reducing manual intervention during routine measurements.
