Multi Calibration Gas Mix NorLab 29L 25ppm H2S 100ppm CO 2.5% CH4

Description

Product Overview

NorLab’s 29‑liter multi‑calibration gas cylinder is engineered to meet the exacting standards of modern laboratory and field gas detection systems. The mixture contains 25 ppm hydrogen sulfide, 100 ppm carbon monoxide, 2.5 % methane (equivalent to 50 % of the lower explosive limit), and 18 % oxygen, with the balance made up of high‑purity nitrogen. Each component is sourced from certified suppliers and blended under ISO 9002 quality management procedures, ensuring traceability to NIST standards. The cylinder dimensions (2.88 × 2.88 × 11.5 in) and lightweight design (12.8 oz) make it easy to handle, store, and transport while maintaining the integrity of the gas mixture throughout its 24‑month shelf life. Compatibility with a broad range of regulator families—including 500 Series Preset Flow, Trigger Control Series, 6000 Series Multiflow, and 8000 Series Demand Flow—provides flexibility for diverse instrument configurations. The product replaces several legacy part numbers (BW CG‑Q34‑4, ISC 1810‑9192, Gasco 34L‑421, Portagas 70096840), consolidating inventory and simplifying procurement for laboratories worldwide.

Usage

This calibration gas is ideal for routine verification, performance testing, and compliance checks of portable and fixed gas detectors used in petrochemical plants, waste‑water treatment facilities, environmental monitoring stations, and research laboratories. Technicians can employ the mixture to simulate real‑world leak scenarios, validate sensor response times, and confirm alarm thresholds for hydrogen sulfide, carbon monoxide, methane, and oxygen detection. The 29‑liter capacity supports multiple calibration cycles, reducing the need for frequent cylinder changes and minimizing downtime. Because the gas blend is NIST‑traceable, results are reproducible across different sites and instruments, facilitating consistent data collection for regulatory reporting and internal quality assurance programs. The cylinder’s robust construction also withstands the rigors of field deployment, making it suitable for use in harsh temperature ranges and high‑humidity environments.

FAQ

What is the recommended storage condition for the cylinder?

The cylinder should be stored in a cool, dry place away from direct sunlight and sources of heat. Maintaining a temperature range of 15‑25 °C (59‑77 °F) helps preserve the gas composition and extends the shelf life up to the full 24 months.

Can this gas mixture be used with any gas detector?

The mixture is compatible with most commercial portable and fixed gas detectors that accept calibration gases in standard cylinder fittings. Always verify the detector’s specifications for pressure range and regulator compatibility before use.

How often should I recalibrate my detectors with this gas?

Calibration frequency depends on the detector’s usage intensity and the regulatory requirements of your industry. A common practice is to perform a full calibration at least quarterly, or after any significant exposure event, to ensure continued accuracy.

Is the cylinder refillable or only single‑use?

This product is supplied as a single‑use cylinder. For refill options, contact NorLab customer service to discuss bulk purchasing programs and custom refill services that meet your specific operational needs.

What documentation is provided with the cylinder?

Each cylinder includes a Certificate of Analysis, NIST traceability report, and a compliance sheet detailing ISO 9002 certification, shelf‑life expiration date, and safety handling instructions. These documents support audit trails and regulatory reporting.
