Gas Flow Control - High sensitive reduced graphene oxide-based room temperature ionic liquid electrochemical gas sensor with carbon-gold nanocomposites amplification

Product catalog summary

Project Overview
This project involves the development of a high-sensitive reduced graphene oxide-based room temperature ionic liquid electrochemical gas sensor, enhanced with carbon-gold nanocomposites. The collaboration is with Zhejiang University, a prestigious institution in China.

Project Management
The project is led by Ping Wang from the Biomedical Engineering department. MCQ Instruments plays a crucial role in controlling the flow rate and mixing gas efficiently.

Technical Specifications

Sensor Calibration: Achieved through precise and stable micro gas flows.
Flow Rates: The MCQ GB100 Series controls flow from 0.1 ml/min to 500 ml/min without cut-off.
Software Automation: The Software PRO Version allows for automated experiments.
Flow Stability: Revolutionary methods ensure stable gas flows even at lower ranges.

Sensor Development
The sensor utilizes carbon-gold nanocomposites synthesized via glucose carbonization and gold nanoparticle deposition. Reduced graphene oxide is electrochemically deposited on a gold electrode, modified with CGNs. A thin-film room temperature ionic liquid serves as the electrolyte, providing stability and a large potential window.

Performance and Testing

The sensor is calibrated for oxygen detection from 0.42% to 21% with high sensitivity and linearity.
Reproducibility is confirmed using chronoamperometry and transient DPA.
The synergic application of RGO and CGNs significantly enhances sensor performance.

Benefits and Savings

Time savings through easier hardware and software setup management.
Compact GAS MIXER channels offer specific calibration for mixtures.

Conclusion
This study introduces a novel approach to high-sensitive electrochemical gas sensors, paving the way for rapid gas exposure monitoring.

DESCRIPTION OF THE APPLICATION AND THE TARGET Gas sensors have received extensive attractions due to their critical roles in environmental monitoring, industry manufacture and human safety. This paper for the ﬁrst time introduces carbon-gold nanocomposites on a reduced graphene oxide based electrochemical gas sensor for high sensitive gas detection. Carbon-gold nanocomposites (CGNs) were synthesized by glucose carbonization and gold nanoparticles deposition using the hydrothermal method. Reduced graphene oxide (RGO) was electrochemically deposited on a screen-printed gold electrode with subsequent...
