If you’re interested, have any questions, or have specific customization requirements, please feel free to contact us at inquiry@atomfair.com.
Operate the instrument only within an ambient temperature range of 15-28°C and relative humidity below 65%, ensuring no condensation occurs. The instrument requires a stable AC220V 50Hz power supply with proper grounding, and the user must supply a compatible computer running WIN7 or WIN10 with a USB interface.
- Ambient Temperature Range: Maintain ambient temperature between 15°C and 28°C to prevent thermal drift and ensure measurement accuracy.
- Relative Humidity Limit: Keep relative humidity below 65% and free of condensation to protect the optical and electronic components.
- Power Supply and Grounding: Connect the instrument to a grounded AC220V 50Hz outlet using the provided ground wire to ensure safe and noise-free operation.
- External Computer and Software: Use a separate computer with Windows 7 or 10 operating system and a USB port to run the infrared software and handle data storage.
How does the Atomfair-DBIR-847's stray light specification affect its ability to analyze low-transmittance samples?
The stray light is ≤0.5%T from 4000 to 650 cm⁻¹ and ≤1%T from 650 to 400 cm⁻¹. This low stray light enables accurate measurement of samples with very low transmittance by minimizing baseline distortion, ensuring reliable absorption values. The specification is critical for analyzing opaque or highly absorbing materials.
What environmental conditions and supporting infrastructure are required to operate the Atomfair-DBIR-847 double beam infrared spectrophotometer?
The instrument requires an ambient temperature of 15–28°C and relative humidity <65% (non-condensing) to maintain optical alignment and detector stability. It operates on AC220V at 50 Hz with a power consumption of 200 W, communicating via USB. A separate computer running Windows 7 or 10 and a printer must be provided by the user.
Does the Atomfair-DBIR-847 support electronic records and audit trails to comply with FDA 21 CFR Part 11 regulations?
Yes, the instrument's software meets GMP/GLP requirements and offers data integrity functions including electronic signature, authority assignment, and audit trail capabilities. These features ensure that spectral data and user actions are recorded in a compliant, traceable manner. The software also supports encrypted data storage through a database.
The Atomfair-DBIR-847 double beam infrared spectrophotometer delivers a 4000-400 cm⁻¹ spectral range with 1.5 cm⁻¹ resolution and GMP/GLP-compliant data management, making it suitable for routine pharmaceutical, chemical, and materials analysis. Its pyroelectric detector and offline-capable software support quantitative and qualitative workflows, though operation requires controlled temperature and humidity conditions.
Positive
- GMP/GLP-compliant data integrity: The system supports electronic signatures, authority assignment, and audit trails, enabling compliance with regulated laboratory environments for pharmaceutical and chemical analysis.
- Versatile spectral analysis modes: Operates in transmittance, absorbance, and energy modes with selectable slit widths and scanning speeds, allowing adaptation to diverse sample types from solids to liquids.
Trade-offs
- Strict environmental requirements: Requires ambient temperature of 15-28°C and relative humidity below 65% without condensation, necessitating controlled laboratory conditions to maintain performance and prevent moisture-related artifacts.
- External computer and printer needed: The instrument does not include a computer or printer; users must supply compatible systems, adding to initial setup logistics and requiring separate procurement.
