HPLC Method for Separation of Methyl Red and Ethyl Red on Primesep 100 Column
December 22, 2022
High Performance Liquid Chromatography (HPLC) Method for Separation of Methyl Red and Ethyl Red on Primesep 100 by SIELC Technologies.
Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Separation of Меthyl Red and Ethyl Red
Methyl Red is a dark-red, single-charged basic dye that turns a deep red in acidic (low pH) solutions. Ethyl Red is a magenta-colored, single-charged basic dye. These two basic dyes can be separated, retained, and analyzed on a Primesep 100 mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a sulfuric acid (H2SO4) buffer. This analysis method can be detected in the Visible spectrum at 520 nm.
Condition
| Column | Primesep 100, 4.6×150 mm, 5 µm, 100A |

HPLC Method for Analysis of Pararosaniline and Ethyl Red on Primesep 100 Column
December 7, 2022
High Performance Liquid Chromatography (HPLC) Method for Analysis of Pararosaniline and Ethyl Red on Primesep 100 by SIELC Technologies.
Separation type: Liquid Chromatography Mixed-mode
Pararosaniline (Basic Red 9) is a popular basic magenta dye and part of the triarylmethane family of dyes. Ethyl Red is a similarly-colored, single-charged basic dye. These two basic dyes can be separated, retained, and analyzed on a Primesep 100 mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a sulfuric acid (H2SO4) buffer. This analysis method can be detected in the visible regime at 520 nm.
