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: 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 chemical compound that contains carbon and fluorine, often used in products like refrigerants and nonstick coatings.

Example: Fluorocarbons are commonly used in air conditioning systems.

Definition: A type of photography that captures images produced on a screen by X-rays, often used in medical imaging.

Example: The doctor recommended a fluorography to check for any lung issues.

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.

Definition: A method used in science to measure and analyze the light emitted by substances when they are exposed to light, helping to identify and quantify small amounts of those substances.

Example: The scientist used fluorometry to analyze the samples for contaminants.

Definition: A type of antibiotic that is effective against a wide range of bacteria and is derived from nalidixic acid.

Example: The doctor prescribed a fluoroquinolone to treat the bacterial infection.

Definition: A device that allows doctors to see the inside of a body or object using X-rays, showing images on a special screen.

Example: The doctor used a fluoroscope to examine the patient's bones for any fractures.

Definition: To use a special device to look inside something, usually for medical purposes, by using X-rays that create a moving image.

Example: The doctor will fluoroscope the patient's stomach to check for any issues.
