"Chromatography" Natural Recordings by Native Speakers
Chromatography is a laboratory technique used to separate, identify, and quantify the components of a mixture. It works by passing a sample through a stationary phase and a mobile phase, allowing the components to separate based on their interactions with each other and with the phases. The separation is often visualized by observing the various components as they emerge from the column, or else detected by adding a chromogenic substance to the mobile phase.
The word "chromatographed" refers to the process of separating a mixture of substances, such as liquids or gases, into their individual components based on their physical or chemical properties. This is typically done using a specialized device called a chromatograph, which uses a stationary phase and a mobile phase to separate the components. The word "chromatographed" is the past tense of the verb "to chromatograph", and it is often used in scientific contexts, particularly in fields such as chemistry, biology, and medicine.
Chromatographic refers to the process of analyzing the components of a mixture by separating them based on their solubility in different solvents or their affinity for different adsorbents. This is often done to identify and quantify the individual components of a mixture, such as in the analysis of biological samples, environmental contaminants, or pharmaceuticals.
Chromatographical refers to the process or method of chromatography, which is a laboratory technique used to separate, identify, and quantify the components of a mixture based on their physical and chemical properties.
Chromatographs are scientific instruments used to separate, identify, and quantify the components of a mixture. They work by passing a sample through a stationary phase, such as a solid or liquid, and a mobile phase, such as a gas or liquid, to separate the components based on their physical and chemical properties, such as size, charge, and solubility. The resulting separated components are then detected and recorded, allowing scientists to identify and quantify the individual components of the mixture.
Chromatolysis is a term used in cellular biology that refers to the degeneration and disintegration of the chromatin (DNA and its packaging proteins) within the nucleus of a cell in response to certain cellular processes or stressors. This can be a normal part of cell development, differentiation, or death, or it can be induced by various stimuli, such as viral infections or chemical treatments.
