Analysis of Inorganic Gases and Light Hydrocarbons

Analysis Analysis of Inorganic Gases and Light Hydrocarbons (GC-BID, GC-TCD)

Analysis of inorganic gases and light hydrocarbons is performed using multiple gas chromatographs (GCs) equipped with detectors having different characteristics. Detectors such as BID (Barrier Discharge Ionization Detector), TCD (Thermal Conductivity Detector), FID (Flame Ionization Detector), and FPD (Flame Photometric Detector) each have unique features and are selected according to the analytical purpose.

Overview

In principle, the BID can detect all gaseous components except helium (He) and neon (Ne), enabling the detection of compounds that cannot be measured with the widely used FID. It also provides higher sensitivity than both FID and TCD.

TCD is commonly used for compositional analysis of inorganic gases. Our GC-TCD system is configured to separate and quantitatively analyze oxygen and argon.

Applications

• Composition analysis of gases such as landfill gas, naturally emitted underground gas, dissolved gas, chemical plant process gas, and biogas

• Trace analysis of inorganic gases (such as carbon dioxide and carbon monoxide) for carbon balance calculations in carbon neutrality initiatives and catalyst development

Workflow (After Your Request)

We propose the most appropriate analytical method based on your objectives. In addition to laboratory analysis, our survey staff can also collect gas samples on-site. Please feel free to contact us for consultation.

Step 1: Confirming Your Objectives

We confirm your objectives, design the survey and analytical methods, and provide a quotation tailored to your requirements.

Step 2: Sample Confirmation (Collection & Analysis)

Our technical staff can collect gas samples on-site according to your requirements.

If you collect the gas samples yourself, we can also provide analysis-only services. In such cases, we will send the designated sampling containers (such as gas sampling bags) in advance.

Step 3: Analysis and Reporting

We compile the analytical results and provide a comprehensive analysis report.

Features

BID (Barrier Discharge Ionization Detector)

Capable of detecting all gaseous components except helium (He) and neon (Ne).

Enables highly sensitive quantitative analysis of trace gaseous components using a small sample volume (for example, CO₂ can be measured at the ppm level).

TCD (Thermal Conductivity Detector)

Our GC-TCD uses a capillary column configuration combined with a PLOT column, allowing the separation and quantitative analysis of oxygen and argon.

Capable of analyzing underground gases and combustible gases at percentage (%) concentration levels.
