Product Summary
The UV-Vis Spectrophotometer is a fundamental piece of Laboratory Spectroscopic Analyzer equipment used to measure the intensity of light absorbed by a sample across the ultraviolet and visible regions of the electromagnetic spectrum. It operates based on the Beer-Lambert Law, allowing for both the qualitative identification of substances and the quantitative determination of their concentration in solution.
Primary Applications
Analytical Chemistry & Quality Control:
Concentration Measurement: Rapid and accurate quantification of chemical species in solutions (e.g., dyes, metals, organic compounds) for quality control and final product assessment.
Purity Verification: Using characteristic absorption spectra to verify the identity and purity of synthesized compounds and raw materials.
Materials Chemistry & New Energy Research:
Nanomaterial Characterization: Analyzing the concentration, size, and aggregation state of nanoparticles (e.g., gold, silver, quantum dots) based on their distinct Surface Plasmon Resonance (SPR) peaks.
Kinetics Studies: Monitoring the rate of chemical reactions by measuring the change in absorbance over time, crucial for optimizing synthesis protocols.
Biochemical / Life Sciences:
Protein and Nucleic Acid Quantification: Standardized techniques for determining the concentration of DNA, RNA, and proteins in research samples.
Configuration and Versatility
Double-Beam Advantage: Double-beam models automatically correct for fluctuations in the light source and solvent background, providing superior baseline stability and more accurate long-term measurements, essential for kinetics and precise quantitative work.
Accessories: Compatible with a variety of accessories, including thermostatted cell holders for temperature-dependent studies and solid sample holders for measuring films, filters, and powders.
Software: User-friendly software includes features for wavelength scanning, fixed-wavelength analysis, calibration curve generation, and data archiving for GLP/GMP compliance.
