Trái Tim Của Sắc Ký Ion

Cột sắc ký nằm ở trung tâm của sắc ký ion (IC). Nếu không có cột phù hợp, ngay cả hệ thống IC mạnh mẽ nhất cũng sẽ không mang lại kết quả chính xác và đáng tin cậy. Đó là lý do tại sao Metrohm cung cấp một loạt các cột IC, giúp bạn thực hiện chính xác các phân tích mà bạn cần.

Separation columns from Metrohm

Our columns form the essential part of high-performance analysis of ions and polar substances by ion chromatography. Ion chromatography columns from Metrohm make use of the known separation mechanisms such as:

  • ion exchange
  • ion exclusion
  • ion pair formation

Anion exchange column resins and cation exchange column resins are the most common stationary phases for the analysis of a broad range of analytes.  

Limitless application options

No matter what your applications require, Metrohm offers the right separation column for every discipline in ion chromatography:

  • anions with or without suppression
  • cations with or without suppression
  • carbohydrates
  • organic acids
  • amines
  • transition metals
  • amino acids
