(Please read this operation manual carefully to achieve the best and consistent column performance for a long time.)
Important Handling Instructions
Caution!
· Please consult the Safety Data Sheet (SDS) of reagents and solvents used with the column
and understand their proper handling methods to prevent potential health hazards or death
from occurring.
· Please wear appropriate personal protective equipment such as lab goggles and gloves
when handling organic solvents and acid and alkaline reagents. Avoid any direct physical
contact to prevent chemical injuries.
Before Using the Column
(1) Please visually inspect the column package and the column surface for any damage.
(2) Please check the product name and serial number (Serial no. or S/N) written on the column package and
adhesive label on the column body.
(3) Please download the Certificate of Analysis (CoA) for the purchased product. The CoA can be downloaded
from Shodex website (https://www.shodex.com/download/). You will be asked to enter the serial number.

1. Introduction

Thank you for purchasing the Shodex product. Shodex IC SI-90 4E is a suppressor type ion chromatography
column for anion analysis, using sodium carbonate eluents. It is suitable for separation of standard inorganic
anions including fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate, as well as organic acid
anions such as acetate and formic acid.

Recommended
IC SI-90 4E
IC SI-90G
Usable solvents are listed below.
(1) In general, a mixture of sodium carbonate solution and sodium bicarbonate solution is used.
(2) The standard eluent is a mixture of 1.8 mM sodium carbonate solution and 1.7 mM sodium bicarbonate
solution. The higher the concentration of sodium carbonate solution, the faster the elution of ions will be.
