FAQ for Fully automatic (fully motor-driven) UV-Vis spectrophotometer
Q1: Why choose a fully automatic (fully motor-driven) UV-Vis spectrophotometer?
A: Motor drive enables automatic wavelength positioning and sample chamber switching, eliminating mechanical wear and human reading errors introduced by manual operation, greatly improving measurement reproducibility and experimental efficiency.
Q2: How should I choose the 4 wavelength scanning speeds in practical applications?
A: Different scanning speeds are designed to achieve a perfect balance between "detection efficiency" and "spectral resolution ". Specific application selection suggestions are as follows:
Fast/Medium Scan: For efficient initial screening and rapid quality control applications, such as QA/QC or real-time tracking of chemical reaction kinetics.
Slow/Ultra-low Scan: For high-precision spectral analysis applications at the research level, such as identification of unknown new substances, analysis of complex multi-component mixtures, or quantitative detection of DNA, proteins, etc., in the pharmaceutical and biological fields where extremely high spectral detail is required.
Q3: What is a UV Vis Spectrophotometer?
A UV vis spectrophotometer is an analytical instrument that measures the absorbance or transmittance of light by a sample across the ultraviolet (190–400 nm) and visible (400–800 nm) wavelength range, used to quantify concentration of substances in solution.
Q4: How Does a UV Vis Spectrophotometer Work?
It shines light through a monochromator to select a specific wavelength. Then splits the beam (or alternates) between a reference (blank) and the sample. It compares the light intensity received by the detector on both sides — the difference gives absorbance, directly proportional to concentration via Beer-Lambert Law (A = \varepsilon c lA=εcl).
