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

CEMS Analyzer Calibration Gas SO2/NO/CO in N2 Mixture — High Precision Multi-component Standard Gas in 150 Bar High Pressure Cylinder

AGEM presents a premium CEMS calibration gas solution designed for instrument manufacturers, environmental monitoring stations, and industrial users who demand consistent, traceable, and reliable calibration standards. This offering — a CEMS calibration gas composed of SO2, NO, and CO blended in N2 within a high-pressure 150 bar cylinder — embodies AGEM’s decades of expertise in specialty and calibration gases. The product is engineered to meet stringent regulatory requirements and evolving gas analyzer calibration trends, delivering a multi-component standard gas that supports accurate, reproducible calibrations across Continuous Emissions Monitoring Systems (CEMS) and other analytical platforms.

Product overview and key features

The AGEM CEMS calibration gas is a high-precision multi-component standard gas formulated to deliver stable concentrations of sulfur dioxide (SO2), nitric oxide (NO), and carbon monoxide (CO) in a nitrogen (N2) balance. Packaged in a durable 150 bar high-pressure gas cylinder, this calibration gas ensures prolonged shelf life and reliable availability for field and laboratory use. The cylinder and gas mixture are produced to meet rigorous quality control procedures, including certificate of analysis, stability testing, and leak-tight integrity assurance.

High-pressure gas cylinders provide distinct operational advantages for heavy users and centralized calibration facilities. The 150 bar high-pressure gas cylinders allow for greater gas volume per cylinder, reducing the frequency of cylinder changes and minimizing logistical costs. For applications that require repeated or continuous calibrations, these high-pressure cylinders support extended service intervals, which is particularly valuable in large industrial plants, power generation facilities, and environmental monitoring networks focused on continuous compliance.

Applications and typical use cases

This multi-component standard gas is optimized for calibration and performance verification of CEMS analyzers that measure SO2, NO, and CO emissions. Typical applications include:

- Continuous Emissions Monitoring Systems: Routine span and zero checks for stack gas analyzers measuring sulfur dioxide, nitric oxide, and carbon monoxide concentrations.

- Regulatory compliance testing: On-site and laboratory calibration to meet regional and international emissions monitoring standards and reporting requirements.

- Instrument manufacturers and calibration service providers: Factory and field calibrations, R&D testing, and instrument verification procedures.

- Environmental laboratories and testing centers: Quality assurance programs, inter-laboratory comparisons, and proficiency testing initiatives.

- Process control and industrial safety: Calibration of gas detection and monitoring systems used in chemical plants, refineries, and power stations.

Technical advantages and innovation

AGEM’s CEMS calibration gas demonstrates several technical advantages that address current gas analyzer calibration trends and user demands. Precise blending: AGEM utilizes advanced gravimetric and volumetric blending techniques, underpinned by robust analytical verification, to ensure each multi-component standard gas meets tight concentration tolerances. Repeatability and traceability: Each cylinder is supplied with a certificate of analysis that documents the nominal concentrations, uncertainty values, and traceability to national or international standards. This supports accurate documentation for audits and regulatory submissions.

Stability and purity: The calibration gas mixture leverages high-purity nitrogen as the balance gas, minimizing interactions and adsorption that can cause drift or contamination. AGEM’s material selection for cylinder interiors, valves, and regulators reduces catalytic interactions that could alter concentration profiles over time. High-pressure cylinder benefits: The 150 bar high-pressure gas cylinders offer a greater molar quantity of calibration gas per cylinder compared to lower-pressure alternatives. This high-pressure format aligns with the operational needs of facilities adopting centralized calibration systems or automated dilution calibration rigs, contributing to improved operational efficiency and reduced downtime.

Multi-component capability: Combining SO2, NO, and CO into a single multi-component standard gas simplifies calibration workflows by reducing the number of cylinders and changeovers required. This efficiency supports faster span checks and alignments with contemporary gas analyzer calibration trends that favor consolidated, high-accuracy standards capable of addressing multiple Analytes in a single calibration step.

Quality control and manufacturing excellence

AGEM’s manufacturing protocols for CEMS calibration gas adhere to strict quality control steps at every stage: raw material qualification, precision blending, cylinder filling at controlled pressures, leak testing, and certificate generation. AGEM’s RD capabilities and regional servicing network reinforce product reliability and ensure rapid response for cylinder exchange, re-certification, or custom gas formulation requests. For users requiring specific concentration ranges or custom blends, AGEM provides bespoke multi-component standard gas solutions with validated uncertainty budgets and stability data. Such customization is particularly useful for specialized calibration routines or for instruments with non-standard measurement ranges.

Traceability and compliance

Each cylinder is issued with comprehensive documentation that includes nominal concentrations for SO2, NO, and CO, associated analytical uncertainties, expiry or recertification dates, and traceability statements. These data packages enable end-users to demonstrate compliance with regulatory frameworks, internal QA/QC protocols, and third-party audits. AGEM’s CEMS calibration gas aligns with industry best practices and supports traceable calibrations consistent with gas analyzer calibration trends emphasizing documented uncertainty and chain-of-custody.

Operational best practices

To maximize performance and ensure safe handling of the CEMS calibration gas, AGEM recommends users adopt established procedures: use compatible regulators designed for high-pressure gas cylinders; perform leak checks at each connection; follow cylinder changeover protocols that minimize exposure and contamination; store cylinders in secure, ventilated areas away from heat sources; and follow recertification intervals based on usage rates and stability data. AGEM’s technical support team can advise on integration with automated calibration manifolds, dilution systems, and analyzer-specific calibration routines, facilitating seamless adoption into existing maintenance regimes.
