Ion chromatography device:
What is the difference between the Supp 4, 5, 7 anion columns for Metrhom 850 device? Does changing the type of column affect the application years and the Correct operation of the device? We used to use the Supp 4 anionic column, but now we want to know if can we replace it with the Supp 5 or 7 column?
Thank you for your answer
