This instrument is designed for quantitative detection of free silica in respirable dust and requires careful handling to maintain optical alignment and data integrity. Environmental stability and proper sample preparation are critical to avoid measurement inaccuracies.
- Environmental Stability Requirement: Operate the instrument in a stable environment free from excessive vibration, dust, and temperature fluctuations to ensure consistent optical performance.
- Sample Preparation Constraint: Use the specified accessories (e.g., KBr powder, tablet press) to prepare homogeneous, transparent pellets, as poor pellet quality directly compromises transmittance accuracy.
- Calibration and Alignment: Verify wave number accuracy and stray light levels periodically using the provided α₂SiO₂ standard to maintain compliance with the stated tolerances.
- Data Integrity: Ensure the USB connection is stable and the Windows-based software is properly installed to prevent data loss or communication errors during spectral acquisition.
This procedure outlines the safe and correct steps to initialize the instrument, prepare samples, and acquire reliable spectra. Following these steps ensures accurate free silica quantification and prolongs instrument life.
Required Equipment: Atomfair Dust Free Silica Tester, Hydraulic tablet press (e.g., FW-5), Agate mortar and pestle, Potassium bromide (KBr) powder
- Power On and Warm Up
Turn on the instrument and allow it to warm up for at least 30 minutes to stabilize the light source and detector. - Prepare the Sample Pellet
Mix approximately 1 mg of dust sample with 100 mg of dried KBr powder and grind thoroughly in an agate mortar. - Press the Pellet
Transfer the mixture to the tablet mold and apply 10 tons of pressure for 2 minutes using the hydraulic press to form a transparent pellet. - Load the Pellet
Place the prepared pellet into the sample holder and insert it into the instrument's sample compartment. - Set Acquisition Parameters
Select the appropriate test mode (e.g., transmittance) and scanning speed (e.g., 'Normal') in the software, then set the wave number range to 4000-400 cm⁻¹. - Acquire Background and Sample Spectra
First record a background spectrum with an empty holder, then run the sample scan to obtain the transmittance spectrum. - Analyze and Export Data
Use the software's peak detection and baseline correction functions to identify silica peaks, then export the report via the USB interface.
How does the Atomfair Dust Free Silica Tester overcome the limitations of the traditional pyrophosphoric acid gravimetric method for free silica detection?
The tester uses computer direct ratio recording and high-energy double blazed grating technology, enabling batch testing and multi-mode analysis while avoiding the complex operation, long cycle times, and low precision associated with the pyrophosphoric acid gravimetric method. Its wave number accuracy is ≤±4 cm⁻¹ in the 4000-2000 cm⁻¹ range and ≤±2 cm⁻¹ in the 2000-400 cm⁻¹ range, with a resolution of 1.5 cm⁻¹ near 1000 cm⁻¹, ensuring reliable quantitative detection of free silica in respirable dust.

The Atomfair Dust Free Silica Tester (SKU AFMSMCFH981) is a Fourier-transform infrared (FTIR) spectrometer configured for quantitative free silica analysis in respirable dust, employing a high-energy double blazed grating and computer direct ratio recording to deliver a resolution of 1.5 cm⁻¹ and transmittance accuracy of ≤±0.2%T across the 4000-400 cm⁻¹ range. Its multi-mode detection (transmittance, absorbance, single beam) and flexible scanning methods support batch testing in industrial hygiene applications, though the instrument requires the included KBr pellet preparation accessories and a stable laboratory environment to maintain spectral integrity.
Positive
- High spectral resolution and accuracy: With a resolution of 1.5 cm⁻¹ near 1000 cm⁻¹ and transmittance accuracy of ≤±0.2%T, the instrument delivers precise quantitative measurements of free silica, meeting the demands of batch testing in industrial environments.
- Multi-mode and multi-scan flexibility: Supports three test modes (transmittance, absorbance, single beam) and three working methods (continuous, repeated, fixed-wavelength scanning), allowing adaptation to diverse analytical protocols and sample types.
Trade-offs
- Requires sample preparation accessories: Accurate analysis depends on the included KBr pellet preparation kit (tablet press, mold, agate mortar, infrared oven, and potassium bromide powder), adding manual steps and potential variability in sample preparation.
- Environmental sensitivity of optical components: The high-energy double blazed grating and TGS receiver are sensitive to humidity and temperature fluctuations; operation in non-laboratory environments may require additional environmental controls to maintain stray light and baseline stability.
