Gastec 3100 Diffusion Tube for Calibration Gas Generation

The Gastec 3100 Diffusion Tube for Calibration Gas Generation provides a scientifically sound method for creating standard gas concentrations. The system operates by allowing a liquid or solid source material to diffuse through a precision-bore capillary tube at a constant temperature. This process results in a highly stable diffusion rate, allowing for the generation of consistent gas mixtures that are vital for calibrating sophisticated gas sensors and analytical instruments.

In industrial safety and environmental monitoring, the reliability of a detector is only as good as its last calibration. The Gastec 3100 Diffusion Tube for Calibration Gas Generation offers a traceable and reproducible alternative to traditional methods. Its ability to maintain long-term stability ensures that sensitivity checks are performed under rigorous conditions, reducing the margin of error in gas detection. For facilities looking to optimize their calibration workflows, this diffusion tube provides a cost-effective and manageable solution for high-level accuracy.

Description

The Gastec 3100 Diffusion Tube for Calibration Gas Generation is a high-precision instrument designed for the stable and continuous production of low-concentration standard gases. This tool is essential for laboratory and industrial technicians who require accurate gas mixtures for the sensitivity testing and calibration of gas detection equipment.

Specifications

  • Product Name: Gastec 3100 Diffusion Tube for Calibration Gas Generation
  • Operating Principle: Molecular Diffusion via Capillary
  • Function: Standard Gas Generation / Sensitivity Checks
  • Compatibility: Gas Detectors, Chromatographs, and Analytical Sensors
  • Maintenance: High durability with replaceable source components

Features

  • Precise Single-Gas Generation: Produces a certified, constant concentration of a specific gas (e.g., H₂S, CO, NO₂, SO₂, Cl₂) with high accuracy, serving as a traceable calibration standard.
  • Permeation/Diffusion Technology: Contains a pure chemical compound sealed within a polymeric tube. The gas permeates through the tube wall at a fixed, temperature-controlled rate, creating a predictable and stable output when used with a carrier gas.
  • Cylinder-Free & Intrinsically Safe: Eliminates the hazards, regulatory burdens, and high cost associated with high-pressure calibration gas cylinders. The tube contains only minute, non-pressurized quantities of chemicals, ensuring safe handling, transport, and storage.
  • NIST-Traceable Certification: Each tube is individually calibrated and supplied with a certificate detailing its specific gas emission rate (ng/min or pg/min) at a defined temperature, ensuring metrological traceability for audit and compliance.
  • Temperature-Controlled Operation: Designed to be used in a dedicated, precision thermostat (oven) that maintains it at a constant temperature (e.g., 30°C, 40°C, or 50°C ±0.1°C), which is critical for maintaining the certified emission rate.
  • Long Service Life & Stability: Offers a typical operational lifespan of 1 to 2 years, providing a cost-effective and stable calibration source over time with minimal maintenance.

Applications

The Gastec 3100 Diffusion Tube for Calibration Gas Generation is widely applied across several technical fields:

  • Calibration of fixed and portable gas detection systems in oil and gas refineries.
  • Sensitivity testing for gas sensors in semiconductor and electronics manufacturing.
  • Quality control in pharmaceutical labs requiring precise gas-sensitive environments.
  • Environmental monitoring and air quality research for atmospheric analysis.
  • Chemical processing plants requiring routine verification of gas monitoring safety tools.
