Definition

1. Noun:
   • Chromatography: A laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed.

Usage Examples

• Noun:
  • Sắc kí là một phương pháp phân tích quan trọng trong hóa học. (Chromatography is an important analytical method in chemistry.)
  • Các nhà nghiên cứu sử dụng sắc kí để tách các chất trong hỗn hợp. (Researchers use chromatography to separate substances in a mixture.)

Advanced Usage

• "sắc kí khí" (Gas Chromatography - GC): A type of chromatography where the mobile phase is a gas.

  • Sắc kí khí thường dùng để phân tích các hợp chất dễ bay hơi. (Gas chromatography is often used to analyze volatile compounds.)

• "sắc kí lỏng" (Liquid Chromatography - LC): A type of chromatography where the mobile phase is a liquid.

  • Sắc kí lỏng hiệu năng cao (HPLC) có độ phân giải rất tốt. (High-performance liquid chromatography (HPLC) has very good resolution.)
