HPLC Method for Analysis of Cerium(III) Nitrate on Newcrom AH Column
May 23, 2023
HPLC Method for Separation of Cerium(III) nitrate hexahydrate on Newcrom AH by SIELC Technologies
Separation type: Liquid Chromatography Mixed-mode
Cerium(III) is a specific oxidation state of the element cerium, which is a lanthanide and a rare-earth metal.
Cerium(III) compounds are often used in a variety of applications. For example, cerium(III) chloride (CeCl3) is a common starting material for the preparation of other cerium-containing compounds and is often used as a reducing agent in organic chemistry. Cerium(III) oxide (Ce2O3), also known as cerous oxide, is used in ceramics and to polish glass.
Cerium(III) nitrate is often used in the laboratory as a cerium(III) source because it is relatively stable and easy to handle. It can be used in a variety of reactions, such as the preparation of other cerium compounds or as a catalyst or co-catalyst in organic reactions.
Cerium(III) Nitrate can be retained and analyzed on a mixed-mode Newcrom AH, 4.6 x 100 mm, 5 µm, 100 A column with a mobile phase consisting of water, Acetonitrile (MeCN), and Ammonium Formate. This analysis method can be detected with an Evaporative Light Scattering Detector (ELSD) or any other evaporative detection method (CAD, ESI-MS).
LOD was determined for this combination of instrument, method, and analyte, and it can vary from one laboratory to another even when the same general type of analysis is being performed.

Separation of Carbonic acid, cerium(3+) salt (3:2) on Newcrom R1 HPLC column
May 16, 2018
Carbonic acid, cerium(3+) salt (3:2) can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
