Atomfair-5000 Free Silica in Dust Tester
Product Overview
In the production environments of the power and coal industries, there are various dusts such as silica dust, coal dust, boiler dust, asbestos dust, cement dust, and welding fume. Such dusts have a high content of free silica and are mostly respirable dust, which poses great harm to the health of personnel exposed to dust, and may cause respiratory diseases such as rhinitis, pharyngitis, tracheitis, and bronchitis. To accurately and efficiently detect the content of free silica in dust and meet the needs of on-site batch testing, the Atomfair-5000 Free Silica in Dust Tester came into being. It has stable performance and easy operation, and can provide reliable support for dust testing work.

The instrument requires a controlled environment with stable temperature and humidity to maintain optical alignment and detection accuracy. Sample preparation must reduce particle size to below 8 micrometers to ensure reliable quantitative analysis.
- Sample Preparation Constraint: Grind dust samples to a particle size of less than 8 micrometers before analysis to ensure accurate free silica quantification.
- Environmental Stability Requirement: Operate the instrument in a vibration-free, dust-controlled environment with stable temperature and humidity to prevent baseline drift and signal noise.
- Data Integrity Protocol: Use the built-in audit trail and data tracking system to maintain traceability and prevent unauthorized modifications of spectral results.
This procedure covers sample preparation, instrument initialization, spectral acquisition, and data processing for routine free silica measurement. Follow each step sequentially to ensure accurate and reproducible results.
Required Equipment: Mortar and pestle or mechanical grinder, Analytical balance, Fourier-transform infrared spectrometer (Atomfair-5000), Data processing software with spectral analysis module
- Prepare Sample
Grind the dust sample to a particle size of less than 8 micrometers using a mortar and pestle or mechanical grinder. - Initialize Instrument

How does the Atomfair-5000 achieve high sensitivity for detecting free silica in respirable dust?
The Atomfair-5000 uses a high-intensity light source with a spherical reflection device to produce uniform and stable infrared radiation, combined with a 24-bit analog/digital converter that significantly improves weak signal detection. It also integrates detection components and a digital signal output to avoid analog transmission interference and reduce electronic noise, ensuring high accuracy for identifying free silica crystal forms.
Can the Atomfair-5000 Free Silica in Dust Tester be integrated into modern laboratory data systems given its Windows XP operating system?
The instrument is built around a high-configured computer running Windows XP with a Chinese operation platform and USB 2.0 interface. It stores experimental results in standard file formats, enabling easy sharing and subsequent processing. However, the legacy OS may require network isolation or upgrade planning for seamless integration with contemporary data management systems.
What sample preparation is required for accurate free silica measurement with the Atomfair-5000?
Dust samples must be ground to a particle size of less than 8 μm to ensure uniform infrared interaction and reliable identification of free silica crystal forms. The instrument is designed for batch testing and comes with special data processing software that quickly calculates free silica content, making proper sample grinding essential for accuracy.
The Atomfair-5000 Free Silica in Dust Tester is a Fourier-transform infrared (FTIR) spectrometer configured for quantitative free silica analysis in respirable dust samples, with a 2.5–25 μm spectral range and integrated 24-bit ADC for high-sensitivity detection. Its dedicated software automates free silica content calculation and supports traceability, but requires samples ground to <8 μm and a Windows XP-based control environment, which may pose compatibility and sample preparation constraints in modern labs.
Positive
- High-sensitivity weak-signal detection: The integrated 24-bit analog-to-digital converter directly outputs digital signals, reducing analog transmission interference and electronic noise, which enhances the detection of weak spectral signals—critical for trace free silica quantification.
- Automated free silica content calculation: Specialized data processing software automatically computes free silica content from spectral data, supports batch testing, and includes a professional tracking and audit system for data integrity and traceability—streamlining routine occupational hygiene analysis.
Trade-offs
- Strict sample particle size requirement: Samples must be ground to a particle size of less than 8 μm before analysis, requiring additional sample preparation steps and consistent milling quality to ensure accurate and reproducible results.
- Legacy operating system dependency: The built-in computer runs Windows XP, an outdated and unsupported operating system, which may introduce cybersecurity vulnerabilities and compatibility issues with modern IT infrastructure and data management systems.
