Gastec 3100 Diffusion Tube for Calibration Gas Generation

Description

Sustained Gas Generation with the Gastec 3100 Diffusion Tube

In the field of industrial instrumentation, the accuracy of a sensor is only as good as the gas used to calibrate it. The Gastec 3100 Diffusion Tube addresses this by providing a dependable method for generating calibration gas through controlled diffusion. Unlike instantaneous gas sources, this tube is designed for applications that require a continuous flow of a single-component gas over extended durations.

The 3100 model is favored by specialists who need to verify the performance of gas detectors or conduct prolonged analytical testing without the fluctuations often associated with other gas generation methods. By maintaining a constant diffusion rate, it ensures that your analytical results remain valid and that your safety systems are always prepared to protect your facility.

Specifications

Based on the provided technical data, the Gastec 3100 system features:

Model Name: 3100.
Generation Type: Single-component gases for calibration.
Duration Capability: Continuous generation over sustained periods.
Analytical Use: Suitable for instrument calibration and specialized testing.

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

On-Site Calibration of Portable Gas Detectors: Enables field technicians to perform accurate bump tests and full calibrations of portable single- or multi-gas monitors without transporting heavy gas cylinders.
Calibration of Fixed Gas Detection Systems: Used to calibrate sensors in fixed industrial safety systems (e.g., in refineries, wastewater plants, manufacturing facilities) where permanent calibration gas plumbing is impractical.
Environmental Monitoring & Research: Provides a precise gas source for calibrating ambient air quality monitors, laboratory analyzers, and research equipment measuring specific gaseous pollutants.
Compliance & Quality Assurance: Essential for industries requiring documented, traceable calibration to meet OSHA, EPA, or other regulatory safety and environmental standards.
Emergency Response & Mobile Labs: Ideal for rapid deployment in incident response vehicles or mobile laboratories where a compact, safe, and reliable calibration standard is needed.
