absorbance
This term is a technical specification used almost exclusively in chemistry and physics, specifically within spectroscopy. It describes the capacity of a material to capture light of a specific wavelength, serving as a quantitative value rather than a general description of the process of absorption.
Because it represents a specific measurement or a physical property, it is treated as an uncountable noun in most scientific contexts. One does not typically refer to multiple absorbances of a single sample, but rather the absorbance value or the absorbance of various samples.
Ý nghĩa
Ví dụ
The absorbance of the sample increased as the concentration of the dye rose.
Check if the absorbance value falls within the linear range of the instrument.
I need to calibrate the spectrophotometer before measuring the absorbance.
The peak absorbance occurs at exactly 280 nanometers for this protein.
Why is the absorbance so low for this specific wavelength?
The researcher noted a significant change in absorbance after adding the reagent.
The researcher noted a significant change in absorbance after adding the reagent.
High absorbance indicates that most of the light was captured by the solution.
I wonder if the absorbance will shift if I change the pH of the buffer.
