Online Gas Chromatograph (CI-PC9300)
The CI-PC9300 adopts helium ionization gas chromatography as its core principle and is equipped with two helium ionization detectors and one high-performance humidity analysis module. Utilizing Longxie’s patented dual-center cutting technology, the system enables full-spectrum analysis of up to 18 decomposition products commonly found in SF₆-insulated equipment. These include: H₂, O₂, N₂, CO, CF₄, CH₄, C₂F₆, C₃F₈, N₂O, CO₂, NF₃, COS, CS₂, H₂S, SO₂, SO₂F₂, SOF₂, and H₂O. An enhanced version can optionally integrate a semiconductor tunable diode laser absorption spectroscopy (TDLAS) module for trace HF detection, meeting the advanced diagnostic needs of power systems and high-voltage equipment monitoring.
Product Feature:
Multi-Channel Parallel Analysis: Enables simultaneous detection of all 18 SF₆ decomposition products in a single injection cycle, significantly improving analysis speed and efficiency;
Optional TDLAS Module: The enhanced version supports integration of a semiconductor tunable diode laser (TDLAS) module for trace-level HF detection, enhancing diagnostic accuracy;
High-Sensitivity PDHID Detection: Equipped with a Pulse Discharge Helium Ionization Detector (PDHID) offering ultra-high sensitivity and linearity for both inorganic and organic compounds, with detection limits reaching ng/g (ppb) levels;
Quick Start-Up with Idle Time Solar Term Mode: Ensures fast, stable instrument initialization, reducing downtime and improving operational readiness;
Advanced Workstation Connectivity: Ethernet-based communication supports real-time multi-channel data acquisition. Capable of managing up to 500 detectors simultaneously. Provides simultaneous reading of all measurement data from the SF₆ decomposition analysis system.
Integrated Database & Equipment Management: Built-in guideline database covering 18 SF₆ decomposition products. Supports integration with GIS (Gas-Insulated Switchgear) equipment records. Data encryption protocols ensure secure data transmission and storage.
