Suppressed Anion Chromatography – Analysis of Anions (SI-36 4D)

The SI-36 4D does not require organic solvent to achieve the separation. Gradient conditions and phosphate ions are eluted within 15 minutes, so analysis time is short.

Monovalent and Divalent Cations in Tap Water (Ethylenediamine EDA)

Monovalent and divalent cations in tap water were analyzed by IC YS-50.

Suppressed Anion Chromatography – Analyzing Oxyhalides and Anions (SI-52 4E)

Oxyhalides and anion standards in tap water were analyzed successfully using IC SI-52 4E. This is applicable to analyzing sources like rain, river water, and runoff.

Suppressed Anion Chromatography – Anion Standards (SI-90 4E)

The application successfully separates the 7 typical ions including F-, Cl-, NO2-, Br-, NO3-, PO43-, and SO42-, and it fulfills US EPA Method 300.1 (A) requirements.
