What is a Spektrofotometer UV Vis?
A spektrofotometer UV Vis is a sophisticated analytical instrument widely used in laboratories and industrial settings to measure the intensity of light at various wavelengths in the ultraviolet (UV) and visible (Vis) spectrum. This instrument operates on the principle of light absorption by a sample, allowing for the quantitative and qualitative analysis of materials, especially in chemical, biological, and environmental research. The versatility of the spektrofotometer UV Vis makes it an indispensable tool for professionals in these fields.
Types of Spektrofotometer UV Vis
There are several types of spektrofotometer UV Vis available on the market, each designed to meet specific analytical needs:
- Single Beam: This type measures the intensity of light both before and after it passes through the sample, making it suitable for routine analysis.
- Double Beam: Equipped with two light paths, one for the sample and another for a reference, the double beam spectrophotometer offers enhanced accuracy and stability.
- Portable Spektrofotometers: Designed for on-site testing, these compact devices offer flexibility for field analysis, perfect for environmental monitoring.
- Multichannel Spektrofotometers: Capable of measuring multiple samples simultaneously, these are ideal for high-throughput laboratories requiring efficient data collection.
