Crucially, the ratio of absorbance at 260nm to 280nm (A260/A280) provides a quick snapshot of purity, indicating the presence of protein or phenol contamination. The 320nm measurement is critical for detecting light scattering caused by particulates in the sample, which can skew results.
Nanodrop Principle Function Overview
Understanding the Key Metrics and Outputs When a sample is measured, the Nanodrop display presents a clear set of data points. In the fast-paced world of molecular biology and biochemistry, the ability to quickly and accurately quantify nucleic acids is paramount.
Because nucleic acids like DNA and RNA have a strong absorbance peak at 260 nanometers, this wavelength is used to calculate concentration. When a sample is placed on the instrument’s optical surface, a beam of light at specific wavelengths passes through it.
Nanodrop Principle Function Overview: How It Measures Purity and Concentration
The device measures how much light is absorbed at these wavelengths, a property known as absorbance. This is where the Nanodrop instrument has become an indispensable tool for researchers, clinicians, and quality control laboratories.
