Portable FTIR Spectrometer FAQ
Q1: Can the BRT-800 Portable FTIR Spectrometer be operated on battery power in the field?
A: Yes. While the standard setup operates on AC power, the BRT-800 offers optional external battery power configurations and wireless connectivity, making it suitable for field testing where line power is unavailable.
Q2: How does the plug-and-play accessory system simplify sample testing?
A: The instrument features auto-recognition technology that automatically detects mounted sampling modules (such as ATR or gas cells) and adjusts system parameters without requiring optical re-alignment or manual calibration.
Q3: How does the system prevent moisture damage during mobile operation?
A: The BRT-800 combines a double-sealed optical bench, protective moisture-proof coatings on the KBr optics and DLATGS detector, and a high-capacity desiccant chamber to maintain internal dryness even in high-humidity field environments.
