Bisphosphonates are the medicines used to treat osteoporosis by preventing bone absorption. In this application, the second generation ibandronate sodium was analyzed using a non-suppressor type anion chromatography column, IC I-524A. Sample: 100 µL 1. Ibandronate sodium 2 mg/mL dissolved in […]

Analysis of Hydrophobic Anions (I-524A) Four hydrophobic anions were analyzed using an anion analysis column for non-suppressor method, IC I-524A. The method optimized here is able to analyze hydrophobic anions without the interference of standard anions. Sample : 20?L 1. […]

  Polyphosphoric Acids (I-524A) Anion standards were analyzed using IC I-524A. This eluent is suited to the separation of three kinds of acids, phosphoric acid(H2PO4–), pyrophosphoric acid(H2P2O72-) and tripolyphosphoric acid(H3P3O102-). EDTA-2Na is added to prevent the complexation of ferrous ion […]

Lithium Tetrafluoroborate was analyzed by ion chromatography (anion) column, IC I-524A. Sample : 10mg/L, 10µ L 1. F – 2. Cl – 3. NO 2– 4. Br – 5. NO 3– 6. BF 4– 7. SO 42- Column : Shodex […]

Anion standards were analyzed using IC I-524A. This figure shows the change in dynamic range of the column with the peak height. There is a linearity in the 0.1 to 10mg/L range for F– and in the 0.1 to 100mg/L […]

Anion standards were analyzed using IC I-524A. A mixture of octanesulfonic acid and boric acid is used as the eluent. This eluent is good for obtaining a low background and a stable baseline even when a large quantity of sample […]

Anion standards were analyzed using IC I-524A, an anion analysis column for non-suppressor method. This figure shows the effect of pH on retention time with a 2.5 mM phthalic acid eluent. Generally, the retention time decreases with the increase of […]

Anion standards were analyzed using IC I-524A. This shows the change in column efficiency with the concentration of the sample when the injection volume is 100micro-L. The column efficiency does not decrease until the sample concentration reaches 10mg/L for Cl– […]

  Anions in tap water were analyzed using IC I-524A. Since phosphoric ion is not present in this sample, F–, Cl–, NO3– and SO42- can be separated in a short time without t he interference of phosphoric ion peak using […]

  Based on the method described in the Japanese regulation for water supply, anions were analyzed using IC I-524A. Sample : 100micro-L each Anion standards 1. H2PO42- 10mg/L 2. F– 1mg/L 3. Cl– 1mg/L 4. NO2– 5mg/L 5. Br– 5mg/L […]
