Overview
The SAIL HERO XHCYQ2000 Ambient Air Particulate Matter Sampler is a programmable, multi-membrane sequential sampling system engineered for unattended, long-term monitoring of PM2.5, PM10, and total suspended particulates (TSP) in ambient air. It operates on the gravimetric principle—drawing air through certified filter media (e.g., quartz fiber or PTFE membranes) at a precisely regulated volumetric flow rate under real-time environmental conditions. The instrument continuously records and compensates for temperature, atmospheric pressure, and flow dynamics to compute standardized volume (at 25 °C and 101.325 kPa) in accordance with ISO 7708, EPA Method IO-3.1, and Chinese HJ 93–2013 technical specifications. Designed for fixed-site deployment in national air quality monitoring networks, regional background stations, and regulatory compliance laboratories, the XHCYQ2000 supports automated, traceable, and audit-ready data acquisition without manual intervention.
Key Features
- Multi-membrane sequential sampling: 10-position rotating filter magazine enables uninterrupted operation over extended campaigns—each membrane can be individually scheduled for 1–23 hours of sampling.
- Intelligent flow control architecture: Dual-stage mass flow sensor and closed-loop feedback algorithm maintain nominal flow at 16.67 L/min with ≤±0.3 L/min deviation and ≤1.5% relative standard deviation across ambient temperature (−20 °C to 50 °C) and pressure (60–106 kPa) ranges.
- Robust power resilience: Built-in non-volatile memory logs fault events during power loss; upon restoration, the system automatically resumes sampling sequence and repositions the current filter to the storage chamber—preserving sample integrity and chronological continuity.
- Integrated environmental sensing: Onboard temperature and barometric pressure transducers meet metrological tolerances per HJ 653–2013 (±2 °C and ≤1 kPa), enabling real-time correction of volumetric flow to standard conditions.
- Remote fault notification: Configurable SMS alerting delivers immediate notifications to up to three designated mobile numbers upon critical anomalies—including flow deviation >5%, motor stall, filter jam, or chamber seal failure.
- Physically segregated compartments: Independent sampling chamber and sealed filter storage zone minimize cross-contamination risk; internal humidity and temperature remain stabilized within ±5% RH and ±1.5 °C during storage—critical for hygroscopic filter preservation prior to gravimetric analysis.
Sample Compatibility & Compliance
The XHCYQ2000 accommodates standard 47-mm and 90-mm circular filters (quartz, Teflon, cellulose ester, or nylon), compatible with subsequent laboratory analysis by gravimetry (HJ 618–2011), ion chromatography (IC), XRF, or ICP-MS. Its performance validation satisfies equivalence requirements against reference methods per HJ 93–2013 (China), EN 12341:2014 (EU), and US EPA EQPM-0697-147. The system supports GLP-compliant workflows: all operational parameters—including start/stop timestamps, flow logs, pressure/temperature readings, and fault codes—are time-stamped and stored internally with write-protection. Audit trails are exportable via USB or RS-232 interface, fulfilling documentation requirements for regulatory submissions under China’s “Air Pollution Prevention and Control Action Plan” and provincial environmental monitoring accreditation schemes.
Software & Data Management
The embedded firmware provides a menu-driven LCD interface with bilingual (Chinese/English) navigation and real-time status visualization (flow curve, clock sync status, battery backup level). Data files adhere to ASCII-based CSV structure with ISO 8601 timestamps and SI-unit labeling—ensuring interoperability with LIMS platforms such as LabWare, Thermo Fisher SampleManager, or custom SQL databases. Optional PC software (XHCYQ-Suite v3.2) enables remote configuration, historical trend analysis, calibration certificate import, and automated report generation compliant with HJ 630–2011 QA/QC reporting templates. All parameter changes are logged with user ID and timestamp; no configuration modification alters pre-existing raw data—supporting 21 CFR Part 11–aligned electronic record integrity where required.
Applications
- Continuous ambient PM monitoring at national reference stations and urban traffic sites
- Source apportionment studies requiring time-resolved filter sets for chemical speciation
- Long-term trend analysis in rural and background locations per WHO Global Air Quality Guidelines
- Validation and co-location testing of beta attenuation (β-ATM) and tapered element oscillating microbalance (TEOM) instruments
- Field calibration support for low-cost sensor networks using collocated gravimetric reference
- Research applications in aerosol science, atmospheric chemistry, and health impact epidemiology
FAQ
What filter types and diameters are supported?
The XHCYQ2000 accepts 47-mm and 90-mm circular filters made of quartz fiber, polytetrafluoroethylene (PTFE), cellulose ester, or nylon—compatible with standard gravimetric and elemental analysis protocols.
Does the system comply with international calibration standards?
Yes—it meets traceability requirements of ISO/IEC 17025 for flow calibration and has been verified against NIST-traceable primary standards; factory calibration certificates include uncertainty budgets per GUM guidelines.
Can sampling schedules be modified remotely?
Local configuration is performed via front-panel interface or USB-connected PC; remote schedule updates require physical access—no cellular/WiFi module is integrated to ensure electromagnetic compatibility and operational security in field deployments.
How is data integrity maintained during power outages?
All sampling metadata—including elapsed time, filter position, flow integrals, and environmental readings—is written to non-volatile flash memory every 10 seconds; power-loss recovery preserves sequence state without data truncation or timestamp corruption.
Is the instrument suitable for outdoor installation in extreme climates?
Rated IP54 for dust and water resistance, with operating range −20 °C to 50 °C and optional solar radiation shield and thermal insulation kit—validated for continuous operation in northern Heilongjiang and southern Hainan province deployments.
