- Environmental Sensitivity: Operate the instrument in a dry, dust-free environment to prevent optical component contamination and signal degradation.
- Data Integrity Requirement: Use the USB2.0 interface with Windows XP compatibility for stable data transfer and avoid signal interference.
This procedure outlines the safe and accurate operation of the infrared spectrophotometer for free silica detection. Follow each step sequentially to ensure reliable results and prevent instrument damage.
Required Equipment: Powder tablet press, Agate mortar, Infrared oven, One-hundred-thousandth electronic balance (0.01mg)
- Prepare Sample
Grind the dust sample in an agate mortar until particles are smaller than 8 μm. - Dry Sample
Dry the ground sample in an infrared oven at 105°C for 2 hours to remove moisture. - Mix with KBr
Mix 1 mg of dried sample with 100 mg of potassium bromide powder in the agate mortar. - Press Pellet
Transfer the mixture to a tablet mold and press at 10 tons for 2 minutes to form a transparent pellet. - Load Pellet
Place the pellet in the sample holder and insert it into the instrument's sample compartment. - Run Scan
Set the scan range to 4000-400 cm⁻¹ and start the full-wavelength scan. - Analyze Data
Use the software to perform baseline correction and peak area integration for free silica quantification.
How does the Atomfair Dust Free Silica Detector distinguish between different crystal forms of free silica?
The detector uses infrared spectrophotometry across the 2.5–25 μm wavelength range (4000–400 cm⁻¹), which covers the characteristic absorption bands of free silica polymorphs. With a wave number accuracy of ≤±2 cm⁻¹ in the 2000–400 cm⁻¹ range and ≤±4 cm⁻¹ in the 4000–2000 cm⁻¹ range, it can reliably identify three crystal forms of free silica as stated in the product description, supporting precise quantitative analysis for occupational health monitoring.
What sample preparation is required before analysis with the Atomfair Dust Free Silica Detector?
Samples must be ground to a particle size of less than 8 μm to ensure effective infrared transmission and accurate quantification. The product specifies a supporting set of accessories including an agate mortar, tablet press, potassium bromide powder, and an infrared oven for drying, which together enable reproducible pellet preparation for reliable spectral data.
What are the system requirements and environmental considerations for operating the Atomfair Dust Free Silica Detector?
The detector integrates a built-in computer running Windows XP with a Chinese operation platform and offers data export via a USB2.0 interface. Its rugged design incorporates electromagnetic drive moving parts and a high-intensity light source with a spherical reflection device, requiring no special environmental controls beyond standard laboratory conditions and supporting both lab and on-site use as described in the product features.
The Atomfair Dust Free Silica Detector (AFMSHMAR390) is an infrared spectrophotometer-based system for quantitative free silica analysis in respirable dust, covering 4000-400 cm⁻¹ with a 24-bit ADC and USB2.0 interface.
