AMS AMS Flue Gas Particulate Sampling System

Overview

The AMS Flue Gas Particulate Sampling System is a precision-engineered, standards-compliant solution for isokinetic sampling of suspended particulate matter (PM) from industrial flue gas streams. Designed and manufactured in Italy, the system implements the fundamental principle of isokinetic sampling—where the linear velocity of sampled gas at the probe inlet matches the local flue gas velocity—to ensure representative collection of particulate mass without bias due to inertial separation or particle bounce. It supports three primary operational configurations: manual (EN 13284-1 / EPA Method 5 & 17), semi-automated (AirCube™ + IsoFlow™), and fully automated (Com2-HE/ISO + IsoFlow™), each validated against internationally recognized regulatory frameworks including EN 13284-1, EPA Methods 5 and 17, ISO 9096, ISO 10780, and ISO 3966:1977. The system’s modular architecture enables field adaptability across diverse stack geometries, temperature profiles (up to 280 °C), and moisture/acid-gas conditions, with integrated thermal management to prevent condensation and sorptive artifacts during filtration.

Key Features

• Probe assembly compliant with EN 13284-1 and EPA Method 17 design specifications, including integrated Pitot tube and calibrated thermocouple for real-time flue gas velocity, differential pressure, and temperature measurement
• IsoFlow™ 201 Pro or 202 isokinetic parameter calculator for on-site determination of optimal nozzle diameter, sampling duration, and volumetric flow rate based on measured stack conditions
• Modular, user-serviceable components: detachable heated sampling head, insulated suction tube, heated filter holder (50 mm diameter), and temperature-controlled filtration chamber
• Thermal management system maintaining probe tip, suction line, and filter housing above dew point—critical for high-humidity or acid-laden flue gases (e.g., coal, waste incineration, cement kilns)
• Compatibility with certified filter media: quartz fiber (max. 280 °C), PTFE-coated glass fiber, and organic binder-free cellulose ester filters—minimizing chemical interference and blank mass contribution
• Support for gravimetric analysis per ISO 1171 and ASTM D3222: pre- and post-sampling filter conditioning in controlled humidity/temperature environments prior to microbalance weighing

Sample Compatibility & Compliance

The system accommodates particulate sampling across a broad operational envelope: flue gas temperatures from ambient to 280 °C, velocities from 2 to 30 m/s, and moisture contents up to 25% v/v. It meets full compliance requirements for regulatory reporting under EU Industrial Emissions Directive (IED) monitoring programs, U.S. EPA Performance Specifications (PS-11), and ISO/IEC 17025-accredited laboratories. All configurations support GLP-aligned documentation: timestamped flow logs, temperature-pressure traceability, nozzle calibration certificates, and audit-ready digital records compatible with 21 CFR Part 11–compliant data management platforms. Filter handling procedures align with EN 13284-2 guidance on blank correction, static charge mitigation, and desiccant-controlled weighing protocols.

Software & Data Management

IsoFlow™ calculators generate ISO-compliant sampling worksheets—including nozzle selection tables, isokinetic deviation reports (<±5%), and cumulative volume tracking—with exportable CSV and PDF outputs. When paired with AirCube™ COM2-ISO or HE-ISO controllers, the system delivers automated logging of all critical parameters (ΔP, T, Q, V_actual, V_std) at 1-second resolution, stored internally and retrievable via USB or RS-232. Firmware supports firmware-signed data integrity checks and configurable alarm thresholds for flow deviation, temperature drift, or filter breakthrough detection. Data files are structured to interface directly with LIMS systems and comply with electronic record retention requirements per ISO/IEC 17025:2017 Clause 7.5.2.

Applications

• Regulatory stack testing for PM₁₀/PM_2.5 emissions from power plants, municipal waste incinerators, and metallurgical furnaces
• Process optimization studies requiring speciated particulate mass balance (e.g., unburnt carbon, heavy metal aerosols, sulfate salts)
• Validation of continuous emission monitoring systems (CEMS) using reference method correlation per EN 14181
• Research-grade characterization of aerosol morphology, hygroscopicity, and reactive surface area following EPA TO-13A or ISO 12103-1 protocols
• Commissioning and periodic performance verification of electrostatic precipitators (ESPs), fabric filters, and wet scrubbers

FAQ

What standards does this system fully support for regulatory reporting?
EN 13284-1, EPA Methods 5 and 17, ISO 9096, ISO 10780, ISO 3966:1977, and ASTM D3222 — with documented traceability to NIST-traceable flow and temperature standards.
Can the system be used for both hot and wet flue gas streams?
Yes — the heated probe, insulated transfer line, and temperature-regulated filter housing maintain all critical surfaces ≥20 °C above local dew point, preventing condensation-induced particle loss or acid deposition.
Is filter media selection standardized or application-specific?
Standardized per EN 13284-1: 50 mm quartz fiber or PTFE-coated glass fiber filters are recommended; alternative substrates require validation per ISO/IEC 17025 method verification protocols.
How is isokinetic accuracy verified during field operation?
Via real-time comparison of stack velocity (measured by calibrated Pitot tube) and calculated nozzle velocity — deviations >±5% trigger automatic flow adjustment or operator alert per ISO 9096 Annex B.
Does the system support remote monitoring or integration with plant SCADA?
Yes — optional RS-485 Modbus RTU interface enables direct integration with industrial control systems; data mapping templates available for Siemens Desigo, Honeywell Experion, and ABB 800xA platforms.
