UV Vis Spectrophotometer FAQ

س1: What is the main difference in performance between wavelength repeatability and accuracy on the BRT-1200UV?

أ: Wavelength accuracy (±2 nm) measures how closely the selected wavelength matches the true physical value. Wavelength repeatability (≤0.5 nm) indicates how consistently the instrument returns to the exact same wavelength during repeated tests, ensuring high measurement precision.

Q2: How does multi-point standard curve fitting work on this model?

أ: The BRT-1200UV allows users to analyze up to 9 standard sample concentrations directly on the instrument to establish a linear regression equation, display the curve, and automatically calculate unknown sample concentrations.

س3: Can I run full spectral scanning or kinetics on the BRT-1200UV?

أ: نعم. While standalone operation handles photometric and quantitative tests, connecting the instrument to a PC via USB with the optional analysis software enables kinetic tracking and full spectral scanning capabilities.
