About Product

Highlight

This EPA Protocol Calibration Gas Mixture is the industry-standard solution for high-precision Continuous Emission Monitoring Systems (CEMS) and environmental compliance. Specifically formulated for the simultaneous detection of Nitric Oxide (NO), Sulfur Dioxide (SO2), and Carbon Monoxide (CO) in a Nitrogen (N2) balance, this mixture is manufactured and analyzed in strict accordance with the EPA Traceability Protocol. Each cylinder undergoes a rigorous multi-step certification process, ensuring that every component is directly traceable to National Institute of Standards and Technology (NIST) or equivalent Reference Materials

To combat the high reactivity of NO and SO2, our cylinders feature advanced internal surface passivation technology, which prevents gas-to-wall interactions and guarantees long-term concentration stability for up to 24 months. This eliminates measurement drift and ensures that your CEMS remains within the tight accuracy tolerances required for local and federal environmental audits. Accompanied by a comprehensive Certificate of Analysis (CoA) detailing the analytical methods and uncertainty scores, this protocol gas provides the legal and technical defensibility needed for industrial power plants, refineries, and waste-to-energy facilities. By delivering superior blend tolerance and rapid sensor response, our EPA protocol gases minimize the risk of non-compliance fines and optimize the efficiency of your emission control strategies

FAQs

What is the lead time for custom 99.9999% (6N) purity mixtures

For ultra-high purity (UHP) gases like CF4/O2, the typical lead time is 10-15 working days. This includes precision blending and multi-stage stability testing to ensure the 6N grade purity and concentration accuracy

How do you guarantee the concentration accuracy of the CF4/O2 mixture

We use the gravimetric method (high-precision weighing) during filling, which is the most accurate blending technique. Each cylinder is analyzed via Gas Chromatography (GC) and comes with a Certificate of Analysis (COA) traceable to NIST or national standards

Is this mixture stable given it contains both Hydrogen H2and Oxygen O2

Yes. We strictly follow safety blending protocols where the concentration of flammable and oxidative components is kept within safe limits or balanced with Argon (Ar) to ensure chemical stability and prevent any hazardous reactions inside the cylinder

What type of cylinder and valve are used for this semiconductor gas

We use internally passivated aluminum alloy cylinders or polished stainless steel cylinders to prevent surface adsorption. For 6N grade gases, we typically equip them with DISS (Digital Intelligent Scheduling System) 660 or SS 316L stainless steel valves to ensure zero leakage and prevent contamination

What are the storage requirements for this gas mixture

Cylinders should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources (temperature < 50° C Ensure the cylinders are secured upright to prevent falling

Do you provide worldwide shipping for hazardous gases

Yes, we specialize in Class 2 hazardous goods logistics. We provide full documentation including MSDS (Material Safety Data Sheet), UN-certified packaging, and DG (Dangerous Goods) declarations for sea or air freight

AGEM presents the CEMS Calibration Gas Mixture NO SO2 CO CO2 O2 N2 Span Gas for Environmental Emission Monitoring Text, a precision-engineered multi-component span gas designed to ensure accurate, reliable, and compliant continuous emissions monitoring systems (CEMS). This CEMS calibration gas is formulated to meet stringent regulatory requirements and to support routine calibration, performance testing, and verification of monitoring equipment used across industrial, power generation, and environmental compliance applications. AGEM’s decades of experience in gas formulation and quality control underpin the performance and consistency of this emission monitoring gases solution.

Product Overview and Key Features

The AGEM CEMS calibration gas mixture contains nitric oxide (NO), sulfur dioxide (SO2), carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), and nitrogen (N2) in controlled concentrations to serve as a comprehensive multi-component span gas for emission monitoring. This environmental compliance gas is available in multiple concentration ranges and cylinder sizes, offering flexibility for diverse calibration protocols and test regimens. Each cylinder is prepared under tightly controlled conditions and delivered with documentation that supports traceability and audit requirements.
