Phonetic Transcription

/presɪpɪˈteɪʃən ˌkrəʊməˈtɒɡrəfi/

Meaning and Usage

Precipitation chromatography refers to a method of chromatography that is used to separate and analyze substances by allowing a precipitate to form from a mixture. This technique is commonly employed in chemical and biological laboratories for the purification and identification of proteins, nucleic acids, and other biomolecules.

Frequency of use: The term is primarily found in scientific and academic contexts, particularly in chemistry and biochemistry. It is more frequently encountered in written form, such as academic papers, textbooks, and laboratory reports, rather than in oral speech.

Example Sentences

1. Precipitation chromatography allows scientists to isolate specific proteins from complex mixtures.

2. (La cromatografía de precipitación permite a los científicos aislar proteínas específicas de mezclas complejas.)

3. In our research, we utilized precipitation chromatography to purify the enzymes for further study.

4. (En nuestra investigación, utilizamos cromatografía de precipitación para purificar las enzimas para su estudio posterior.)

5. Advances in precipitation chromatography have led to more efficient methods for analyzing biological samples.

6. (Los avances en la cromatografía de precipitación han llevado a métodos más eficientes para analizar muestras biológicas.)

Idiomatic Expressions

While "precipitation chromatography" itself does not feature in common idioms or colloquial expressions, the terms "precipitation" and "chromatography" often appear in various scientific phrases and idioms related to separation processes or the analysis of mixtures.

Example Idiomatic Expressions

1. Precipitation reaction - "The precipitation reaction was crucial for determining the composition of the unknown mixture."

2. (La reacción de precipitación fue crucial para determinar la composición de la mezcla desconocida.)

3. Separation science - "Separation science, including techniques like precipitation chromatography, is essential for modern analytical chemistry."

4. (La ciencia de separación, incluidas técnicas como la cromatografía de precipitación, es esencial para la química analítica moderna.)

5. Chromatographic analysis - "The chromatographic analysis revealed unexpected interactions between the compounds in the sample."

6. (El análisis cromatográfico reveló interacciones inesperadas entre los compuestos de la muestra.)

7. Art of separation - "The art of separation, as practiced in chromatography, is key to understanding chemical interactions."

8. (El arte de la separación, como se practica en la cromatografía, es clave para comprender las interacciones químicas.)

Etymology

The term "precipitation" derives from the Latin word "praecipitatio," which means "to fall or throw down." "Chromatography" comes from the Greek words "chroma," meaning "color," and "grapho," meaning "to write," originally referring to the technique’s use in separating colored compounds. The combination of these terms describes a method that precipitates substances based on their distinct properties.

Synonyms and Antonyms

Synonyms: - Fractionation chromatography - Affinity chromatography (in some contexts)
