UV Vis Spectrophotometer FAQ
Q1: What are the main benefits of the ≤0.001 Abs/30 min baseline drift in the BRT-5600UV?
A: Ultra-low baseline drift ensures that the instrument maintains optical baseline flatness over long testing shifts. This eliminates frequent manual recalibrations and guarantees high quantitative repeatability.
Q2: How does the ±0.3 nm wavelength accuracy improve research results?
A: The high wavelength accuracy of ±0.3 nm, combined with 0.2 nm repeatability, ensures precise alignment with target absorption peaks. This minimizes measurement variance across complex chemical and biological assays.
Q3: Can the light source switching point be adjusted manually?
A: Yes, the light source switching point between the deuterium lamp and the tungsten halogen lamp can be adjusted within the range of 294 nm to 365 nm to accommodate specific sample absorption characteristics.
