The Atomfair-FTIR-518 requires a controlled environment with low humidity and minimal dust to prevent damage to its interferometer and beamsplitter. Users must monitor the silica gel desiccant and activate the dehumidification module to maintain optimal operating conditions.
- Moisture and dust management: Place the instrument in a clean, dry environment and replace the desiccant when the silica gel indicator changes color.
- Test method selection: Select transmission or ATR attenuated total reflection based on the asphalt sample state to obtain accurate spectra.
- Dehumidification module activation: Activate the built-in heating and dehumidification module during operation to extend the lifespan of internal components.
What signal-to-noise ratio and wavenumber accuracy does the Atomfair-FTIR-518 achieve, and how do they support accurate SBS modifier content determination?
The Atomfair-FTIR-518 delivers a signal-to-noise ratio of 30,000:1 (RMS at 2100 cm⁻¹, 4 cm⁻¹ resolution, 1-minute collection) and a wavenumber accuracy of 0.01 cm⁻¹. These specifications, combined with the Michelson interferometry principle and high-quality zinc selenide beamsplitter, enable precise and reproducible quantification of SBS modifier content in asphalt even with a single 3-second scan.
What sample preparation and measurement modes are supported by the Atomfair-FTIR-518 for testing SBS modified asphalt?
The Atomfair-FTIR-518 supports both transmission and ATR attenuated total reflection measurement modes. For solid or highly absorbing asphalt samples, ATR eliminates the need for extensive preparation. Optional accessories such as a liquid cell, thin layer sample holder, and high-speed shearing machine further expand compatibility with various sample states, making the instrument adaptable for different testing protocols.
What moisture protection and maintenance features does the Atomfair-FTIR-518 include to ensure reliable long-term operation?
The Atomfair-FTIR-518 incorporates a multi-layer sealed moisture-proof and dust-proof interferometer with a visible silica gel window, allowing easy desiccant replacement without opening the instrument cover. A built-in heating and dehumidification module maintains a stable internal environment to protect core components. These design choices minimize downtime and extend operational life, especially in humid laboratory conditions.
The Atomfair-FTIR-518 is a Fourier transform infrared spectrometer optimized for SBS modified asphalt analysis, utilizing a Michelson interferometer with a zinc selenide beamsplitter to deliver a signal-to-noise ratio of 30000:1 and 0.01 cm⁻¹ wavenumber accuracy. Its 3-second scan time and support for transmission and ATR methods enable rapid, versatile modifier content quantification, while the sealed, heated interferometer housing and dehumidification box support stable operation in humid lab environments.
Positive
- High spectral resolution and accuracy: With a signal-to-noise ratio of 30000:1 (RMS at 2100 cm⁻¹) and wavenumber accuracy of 0.01 cm⁻¹, the instrument reliably resolves modifier content in SBS asphalt, supporting precise quantitative analysis.
- Fast batch analysis capability: A single scan completes in 3 seconds, enabling rapid throughput for batch sample testing in production quality control and incoming inspection workflows.
Trade-offs
- Moisture-sensitive optical core: The interferometer and zinc selenide beamsplitter require a dry environment; the built-in heating/dehumidification module and dehumidification drying box are essential to prevent moisture damage, adding operational overhead.
- Limited spectral range for some applications: The 4000–650 cm⁻¹ range excludes far-infrared regions, which may restrict analysis of certain inorganic or low-frequency vibrational modes relevant to some asphalt additives.
