AGEM presents the CEMS calibration gas NO NO2 NH3 N2 mixture span gas for SCR DeNOx system flue gas analyzer calibration, a precision-engineered gas blend designed to meet stringent emissions monitoring requirements. This CEMS calibration gas solution is formulated to support accurate SCR DeNOx span gas procedures and ensure reliable flue gas analyzer calibration across industrial combustion sources. By delivering stable concentrations of NO, NO2, and NH3 in an inert N2 balance, AGEM’s product addresses the needs of continuous emissions monitoring systems, regulatory compliance, and optimized DeNOx performance.
Product Overview and Purpose
The AGEM CEMS calibration gas NO NO2 NH3 N2 mixture is a multi-component calibration standard intended for use in calibration, span checks, and verification of catalytic reduction control systems and continuous emissions monitoring systems (CEMS). As an SCR DeNOx span gas, this mixture enables technicians and plant operators to perform precise calibration of flue gas analyzers that measure nitrogen oxides and ammonia slip. Proper flue gas analyzer calibration is critical for accurate reporting, regulatory compliance, and effective SCR catalyst operation. AGEM’s span gas composition is carefully selected to reflect the typical species encountered in post-combustion flue streams, providing a realistic and reliable reference for measurement systems.
Key Features
- Multi-species certified mixture: The blend contains certified concentrations of NO, NO2, and NH3 in an N2 balance to facilitate comprehensive flue gas analyzer calibration and SCR DeNOx testing. This CEMS calibration gas composition simplifies calibration workflows by providing all necessary species in one cylinder.
- High-accuracy certification: Each cylinder is accompanied by a Certificate of Analysis (COA) detailing certified values, uncertainty, and stability data to support audit trails and compliance reporting. The analytical traceability ensures confidence in measurement results for flue gas analyzer calibration and regulatory submissions.
- Long-term stability: AGEM applies rigorous gas blending and stabilization processes to minimize drift and decomposition, delivering reliable SCR DeNOx span gas performance over the product shelf-life. This stability reduces the frequency of recalibration and lowers operational costs for continuous emissions monitoring systems.
- Low cross-interference formulation: The NO NO2 NH3 N2 mixture is optimized to minimize interaction among species, preventing in-cylinder reactions that could compromise accuracy. AGEM’s proprietary techniques preserve component integrity for effective flue gas analyzer calibration.
- Compliance-focused packaging: Cylinders are available in industry-standard sizes with valve and fitting options suitable for CEMS calibration rigs, on-line calibration manifolds, and portable calibration kits. Safety labeling, batch IDs, and COA access are standard to support rigorous quality control and traceability.
Applications
- Continuous emissions monitoring (CEMS): Use the AGEM CEMS calibration gas to verify and calibrate NOx and NH3 measurement channels on CEMS analyzers. Regular use of certified span gas helps demonstrate compliance with environmental permits and emission limits.
- SCR DeNOx system tuning and performance verification: The SCR DeNOx span gas plays a critical role in establishing ammonia-to-NOx dosing rates, evaluating catalyst activity, and detecting ammonia slip. Accurate span gas calibration helps optimize reagent economy and minimize environmental impact.
- Flue gas analyzer calibration and linearity checks: Labs and field technicians rely on multi-component mixtures for span, zero, and multi-point calibrations. AGEM’s NO NO2 NH3 N2 mixture is ideal for flue gas analyzer calibration across a range of process conditions.
