PRINCIPLES AND PRACTICE OF CHROMATOGRAPHY

Sắc ký, mặc dù chủ yếu là một kỹ thuật tách, chủ yếu sử dụng trong phân tích hóa học. Tuy nhiên, đến một mức độ hạn chế, nó cũng được dùng cho các mục đích dự bị, đặc biệt đối với sự cô lập của một lượng tương đối nhỏ các vật liệu có giá trị nội tại tương đối cao. Sắc ký có lẽ là kỹ thuật mạnh mẽ nhất và linh hoạt có sẵn cho các nhà phân tích hiện đại trong một quá trình bước duy nhất nó có thể riêng biệt một hỗn hợp thành...
