Definition: Relating to or derived from the chemical element fluorine, often used in chemistry and materials science.

Example: The fluoric compounds are essential in various industrial applications.

Definition: An instrument used to measure the intensity of fluorescent light emitted from a sample when it is exposed to a specific wavelength of light.

Example: The scientist used a fluorimeter to analyze the samples for their fluorescent properties.

Definition: Relating to or using fluorometry, a technique for measuring the fluorescence of a substance.

Example: The fluorimetric analysis revealed the presence of trace elements in the sample.

Definition: A scientific method used to measure the intensity of fluorescent light emitted by a substance when it is exposed to light of a specific wavelength.

Example: Fluorimetry is commonly used in laboratories to analyze the concentration of substances in a solution.

Definition: To add fluorine to a substance or compound, often to change its properties or enhance its performance.

Example: The chemist decided to fluorinate the compound to improve its stability.

Definition: Describing a compound that has had one or more hydrogen atoms replaced by fluorine atoms, or that has been treated with fluorine or hydrofluoric acid.

Example: The chemist worked with fluorinated compounds to improve their stability.

Definition: To treat or combine a substance with fluorine or fluorine compounds.

Example: The chemical was fluorinated to enhance its properties.

Definition: A chemical process that adds fluorine to a substance or compound.

Example: The fluorination of the compound improved its stability and reactivity.

Definition: A pale yellow, poisonous gas that is very reactive and belongs to the group of elements known as halogens. It is used in many important industrial processes and is the most electronegative element.

Example: Fluorine is used in the production of certain types of plastics and chemicals.

Definition: A type of dye that glows under certain light, used to color biological samples for study.

Example: The scientist used a fluorochrome to highlight the cells in the tissue sample.

Definition: A device used to detect and measure the light emitted by a substance when it is exposed to radiation, particularly in the context of fluorescence.

Example: The scientist used a fluorometer to analyze the samples for their fluorescent properties.
