Overview
XENON series combines a stable double-beam optical path with ARM control for
rapid, precise photometric and quantitative work. Modes include
Photometric, Quantitation (curve/calibration), Spectral Scanning, Kinetics,
DNA/Protein and Reflectance. Auto zero/blank, peak/valley detection, linear
regression and timed printing are built-in. Power-loss protection preserves
data and calibration. :contentReference[oaicite:2]{index=2}
