Product Description UV1900 Series Dual-Beam Ultraviolet-Visible SpectrophotometerProduct DescriptionThe UV1900 series dual-beam ultraviolet-visible spectrophotometer is a high-performance analytical instrument designed for precise laboratory measurements. It adopts a rigorous and precise dual-beam optical system and circuit control system, ensuring excellent performance in multiple key indicators:High accuracy: Meets strict standards for measurement precision, ensuring reliable data results.Excellent repeatability: Stable measurement performance, minimizing data deviation between repeated tests.Low noise & low stray light: Reduces interference factors, ensuring the clarity and accuracy of measurement signals.Exceptional stability & wide linear range: Maintains consistent performance during long-term operation and adapts to different concentration ranges of samples.The core design of this spectrophotometer lies in its spectroscopic system: it divides the light source into two independent beams. One beam passes through the sample cell, while the other goes through the reference cell. Both beams alternately illuminate the same high-sensitivity detector. Through real-time comparison of the sample light signal and the reference light signal, the instrument automatically deducts background interferences such as light source fluctuations and solvent absorption. This design fundamentally enhances the stability and accuracy of measurements, making it a trusted choice for laboratory analysis.Core Features & Advantages1.

What is a Dual-Beam Spectrophotometer?A dual-beam spectrophotometer is a widely used optical analysis instrument, mainly used to measure the absorption and transmission characteristics of sample solutions. Its unique dual-channel design ensures superior performance compared to single-beam instruments:The light emitted by the radiation source is split into two separate channels.One channel (reference channel) passes through the reference cell (filled with blank solvent), and the other channel (sample channel) passes through the sample cell (filled with the solution to be tested).By comparing the two channels' signals, it effectively eliminates external interference and obtains accurate sample analysis data.Working PrincipleThe UV1900 series operates based on the principle of ultraviolet-visible absorption spectroscopy, with a clear and efficient working process:Light Source Generation: A stable, monochromatic, and collimated radiation source emits electromagnetic waves in the visible or ultraviolet wavelength range, providing a reliable light source foundation for measurements.Beam Splitting: The incident monochromatic light is split into two parallel beams by the beam splitter:Beam 1: Passes through the reference cell (blank solution, no interaction with the substance to be measured).Beam 2: Passes through the sample cell, interacts with the target substance (absorbs specific wavelengths of light), and then travels to the detector.Signal Detection: The high-sensitivity detector receives the light signals from both the sample channel and the reference channel, and converts these optical signals into electrical signals.Data Calculation: The instrument's signal processing system compares the intensity differences of the two electrical signals. Based on the Lambert-Beer law, it calculates the absorption or transmission degree of the sample at different wavelengths, and finally outputs the measurement results.
