Rapid Greenhouse Gas Analysis System

Nexis GC-2030 AOC-6000 Plus

Greenhouse gases (GHGs) contribute to the greenhouse effect by absorbing infrared (IR) energy from sunlight and reflecting this energy back towards the Earth. Shimadzu offers a Gas Chromatography system that facilitates easy qualitative and quantitative analysis of three major GHGs: methane, carbon dioxide, and nitrous oxide.

System Overview

Achievable LODs for GHGs and representative chromatograms for analysis of standards.

System Schematic

Key 1 SPL - Split/Splitless Injection Port
Sample introduced and flow is reliably split onto 2 columns.

Key 2 Analytical Columns
Analytes separated optimally using Shimadzu’s SH-Q-BOND and QS-BOND phases.

Key 3 Electron Capture Detector (ECD) and Vent Valve
Electron Capture Detector for trace detection of N₂O, protecting the detector by flushing compounds to vent using the in-line 6-port valve.

Key 4 Flame Ionization Detector (FID) with Jetanizer™
Provides reliable analysis of CO₂, CH₄ and CO, and can be expanded to light hydrocarbons.

Key A Exetainer® Vial Sampling
Increase sample throughput with a highly reproducible autosampler – AOC-6000 Plus.

Direct, highly reproducible sampling from Exetainer® vials (72, 144 or 216 positions possible).

Includes Liquid and Headspace injection modules for additional flexibility and futureproofing.

Key B Manual Gas Sampling
Additional 6-port valve provides ability to sample e.g. Tedlar bags through a fixed volume loop.

Key C Deans Switch Device

Option to vent unwanted compounds before they reach the FID.

Reliably remove acetylene (known catalyst coking agent) or hydrogen sulfide.
