chromatographic

chromatographic的音标为["krəʊmətəgræfɪk]，基本翻译为“色层分析的，色谱分析的”，速记技巧为“chromatogram + -ic → 色谱分析的”。

chromatographic这个词源自希腊语中的“chroma”（颜色）和“graphos”（写或画）。它的意思是“与色谱有关的”。

变化形式：在词形上，chromatographic没有明显的变化形式。

英文小作文：

Chromatography is a powerful tool for separating and identifying substances in a sample. It can be used for a wide range of applications, including pharmaceutical, environmental, and food science research. Chromatography can separate components based on their physical or chemical properties, such as size, charge, or solubility in a solvent. High performance liquid chromatography, thin layer chromatography, and gas chromatography are some of the most commonly used types of chromatography.

In pharmaceutical research, for example, chromatography is used to separate and identify active pharmaceutical ingredients from excipients and other impurities in a drug substance sample. In environmental analysis, chromatography is used to detect pollutants in water or soil samples, while in food science, it is used to identify additives or contaminants in food products.

Chromatography has revolutionized the way scientists and researchers approach chemical analysis and has opened up new avenues for research and development in various fields. It is a versatile technique that continues to evolve and improve, making it an essential tool in modern analytical chemistry.
