A UV-Vis spectrophotometer measures how much ultraviolet and visible light a sample absorbs, which supports both identification and concentration measurement. It is one of the most widely used instruments in analytical and quality control laboratories.
Pharmaceutical and Life Sciences
Quantify active ingredients, measure DNA and protein concentration, and run assays that support quality control. UV-Vis methods underpin many pharmacopeia tests and routine release testing.
Water and Environmental Analysis
Measure parameters such as nitrate, phosphate, and chemical oxygen demand. Reliable absorbance data supports environmental monitoring and regulatory reporting.
Food, Beverage, and Chemical QC
Check color, additives, and concentration of key components to confirm product consistency and detect contamination.
Academic and Research Laboratories
Study reaction kinetics, characterize new compounds, and teach core analytical chemistry, all from a single benchtop instrument.
1. Wide Wavelength Coverage
The instrument measures across the ultraviolet and visible range, with many models extending into the near-infrared, which supports a broad set of applications.
2. Single- and Double-Beam Options
Single-beam designs offer value for routine work, while double-beam designs correct for lamp drift in real time for higher stability and accuracy.
3. Low Stray Light
Quality optics keep stray light low, which preserves accuracy at high absorbance and improves confidence in concentration measurements.
4. Stable Light Sources
Deuterium and tungsten-halogen lamps provide steady output across the UV and visible ranges, supporting reproducible results over long sessions.
5. Flexible Accessories
Cuvette holders, sippers, and fiber-optic probes adapt the instrument to liquids, small volumes, and specialized sampling needs.
6. Compliance-Ready Software
Software supports photometric measurement, spectrum scanning, kinetics, and quantitative analysis, with options that support data-integrity requirements such as 21 CFR Part 11 for regulated laboratories.
A UV-Vis spectrophotometer determines what is in a sample, and how much, by measuring the light it absorbs in the ultraviolet and visible range. Many molecules absorb light at specific wavelengths, so absorbance reveals both identity and concentration.
The Beer-Lambert Law
The instrument shines a beam of light through the sample and compares the light entering with the light leaving. The fraction absorbed follows the Beer-Lambert law, which states that absorbance is proportional to the concentration of the absorbing substance and the path length the light travels through it. In practice, this means a more concentrated sample absorbs more light.
How the Instrument Builds a Measurement
A light source, usually a deuterium lamp for ultraviolet and a tungsten lamp for visible light, produces a broad beam. A monochromator selects one wavelength at a time and passes it through the sample. A detector then measures the transmitted light and the system calculates absorbance. By plotting absorbance against a set of known standards, the analyst converts a reading into an exact concentration. This direct relationship between absorbance and concentration is why UV-Vis is a core tool for quantitative analysis.
