Applications:


Separation of Trichloroacetic acid on Newcrom R1 HPLC column

Trichloroacetic acid 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.

HPLC Separation of Acetic acid, Chloroacetic acid, Dichloroacetic acid, Trifluoroacetic acid,   Trichloroacetic acid
HPLC.cloud View on hplc.cloud Acetic acid and its substitution derivatives, chloroacetic acid, dichloroacetic acid, trichloroacetic acid, difluoroacetic acid and trifluoroacetic acid, are heavily used as building blocks for more complex compounds in organic synthesis. All six acids can be isocratically separated in HPLC using Newcrom BH mixed-mode column with acetonitrile (ACN) and water mobile phase with sulfuric acid (H2SO4) as buffer and UV detected at 200nm.

HPLC Separation of Bromoacetic and Chloroacetic acids on Newcrom B Column
HPLC.cloud View on hplc.cloud Bromo- and chloro- acetic acids are widely used in organic chemistry.  Their similar structure makes the acids difficult to retain and separate on reverse-phase HPLC columns.  By using Newcrom BH mixed-mode column which also has ion-exchange properties, the separation can be achieved with a simple isocratic method and relatively short time with a mobile phase of acetonitrile (ACN), water and sulfuric acid (H2SO4) buffer.
