FCS-10 Metal Dust and Asbestos Fiber Sampler

Overview

The FCS-10 Metal Dust and Asbestos Fiber Sampler is a portable, battery-powered personal sampling instrument engineered for quantitative collection of inhalable metal particulates and asbestos fibers in occupational environments. It operates on the principle of gravimetric analysis: airborne particles—including elemental metals (e.g., lead, chromium, nickel, cadmium, beryllium, manganese) and their oxides, as well as amphibole and serpentine asbestos fibers—are drawn at a controlled flow rate through a pre-weighed membrane filter (typically mixed cellulose ester or polycarbonate, pore size 0.8–5.0 µm). Post-sampling, the filter is re-weighed under controlled laboratory conditions (ISO 7709, ISO/IEC 17025-compliant balance environment), and mass concentration (mg/m³) is calculated using standardized gravimetric formulae per NIOSH Method 7300 (Metals), OSHA ID-160 (Asbestos), and EN 481 (Inhalable Fraction). Designed for compliance with workplace exposure limit (WEL) monitoring requirements, the FCS-10 supports both total dust and respirable fraction sampling when paired with appropriate cyclones or IOM samplers.

Key Features

• Programmable digital timer with precision of ≤±0.1% over full range (1 minute to 99 hours 59 minutes), enabling flexible shift-based or long-duration exposure assessments.
• Two selectable flow ranges: 1–10 L/min (optimized for total dust and larger metal aerosols) and 1–15 L/min (suitable for high-flow asbestos fiber sampling per ISO 8518 and ASTM D7200).
• High-efficiency brushless DC motor delivering consistent vacuum pressure (>1500 Pa) across variable filter loading conditions—critical for maintaining flow stability during extended sampling campaigns.
• Real-time LCD display showing elapsed time, remaining battery voltage, charging status, and instantaneous flow rate (when calibrated flowmeter is installed).
• Integrated battery management system with low-voltage warning, auto-shutdown protection, and full-cycle charge monitoring (1 A constant-current charging).
• Compact ergonomic housing (205 × 135 × 115 mm; 2.3 kg) designed for belt-mounting or tripod deployment—meets ISO 13137 for personal sampler ergonomics and field robustness.
• Acoustically damped internal architecture ensuring operational noise <75 dB(A) — compliant with ISO 9612 acoustic measurement protocols for worker-worn devices.

Sample Compatibility & Compliance

The FCS-10 is compatible with standard 25-mm and 37-mm diameter membrane filters (MCE, PVC, PTFE, polycarbonate), including NIOSH-approved filters for asbestos fiber counting (e.g., mixed cellulose ester, 0.8 µm pore size). When used with an IOM inhalable sampler head or GK2.69 cyclone, it supports respirable dust fraction collection per ISO 7708 and ACGIH BMDS definitions. The instrument conforms to core regulatory frameworks governing occupational hygiene sampling: NIOSH Manual of Analytical Methods (NMAM) Chapter 2, OSHA Technical Manual Section II, EU Directive 2004/37/EC (CARC), and China’s GBZ/T 192.1–2019 (Workplace Air — Determination of Dust). Its flow accuracy (±2.5% F.S.) and stability (≤±5%) satisfy ISO 8518:2011 requirements for asbestos fiber sampling pumps.

Software & Data Management

While the FCS-10 operates as a standalone hardware device without embedded Bluetooth or USB data logging, its timer and battery telemetry outputs are fully traceable via manual logbook entries or integration with external electronic diaries compliant with GLP/GMP documentation standards. All timing and power parameters meet auditability criteria for ISO/IEC 17025-accredited laboratories conducting occupational exposure assessments. Optional calibration certificates (traceable to NIM or CNAS-accredited flow calibrators) support 21 CFR Part 11–aligned record retention when paired with validated LIMS workflows. Firmware logic ensures no user-modifiable clock drift—timer integrity is preserved even after battery depletion and recharge cycles.

Applications

• Quantitative assessment of metal fume exposure in welding, smelting, electroplating, and battery manufacturing facilities.
• Asbestos abatement verification and post-remediation clearance sampling in construction, shipbreaking, and legacy infrastructure maintenance.
• Baseline exposure characterization for occupational health surveillance programs aligned with WHO/ILO guidelines.
• Educational use in university industrial hygiene labs for hands-on training in NIOSH/OSHA sampling methodology.
• Field validation of engineering controls (e.g., local exhaust ventilation efficiency) through time-weighted average (TWA) and short-term exposure limit (STEL) sampling.
• Supporting regulatory submissions under REACH Annex XVII, RoHS, and China’s “Three-Year Action Plan for Occupational Disease Prevention” (2022–2025).

FAQ

What filter types are recommended for asbestos fiber sampling with the FCS-10?
Mixed cellulose ester (MCE) filters with 0.8 µm pore size are recommended per NIOSH Method 7400 and ISO 8518. Polycarbonate filters may be used for phase contrast microscopy (PCM) or transmission electron microscopy (TEM) analysis.
Can the FCS-10 maintain stable flow under high-resistance filter loading?
Yes—the pump delivers >1500 Pa vacuum pressure and demonstrates ≤±5% flow variation across the full operating range, even with aged or loaded filters typical in 8-hour TWA sampling.
Is the FCS-10 suitable for respirable dust sampling?
When coupled with a certified respirable cyclone (e.g., GK2.69 or IOM sampler), the FCS-10 meets ISO 7708 and EN 481 specifications for respirable fraction collection at 2.2–2.5 L/min.
Does the instrument include calibration traceability documentation?
Calibration certificates traceable to national metrology institutes (e.g., NIM China) are available upon request and comply with ISO/IEC 17025 requirements for accredited calibration providers.
What is the expected service life of the lithium-ion battery pack?
Rated for ≥300 full charge/discharge cycles under normal usage; capacity retention remains >80% after 2 years of biweekly field deployment.
