Detailed technical brochures and software guidance for Hitachi double-beam spectrophotometers (similar to the U-2800/2900 series) are available from Techcomp Hong Kong Perform a baseline scan or auto-zero to calibrate
: Insert your reference solvent into the holder and press AUTO ZERO (or "Blank") to set the baseline before measuring samples.
The Hitachi U-2800 utilizes a double-beam optical system that splits light into a sample beam and a reference beam. This design compensates for light source fluctuations, ensuring high baseline stability and precise measurements across a wavelength range of 190 nm to 1100 nm. Key Specifications : Double-beam ratio recording system Wavelength Range : 190 to 1100 nm Spectral Bandwidth : 1.5 nm Stray Light : Less than 0.05% (at 220 nm and 340 nm) Wavelength Accuracy : ±0.3 nm If you share with third parties, their policies apply
Never touch the mirrors or internal optical elements directly. Clean the sample compartment gently with a lint-free wipe if any liquid spills.
