Pararosaniline (Basic Red 9) is a popular basic magenta dye and part of the triarylmethane family of dyes. Crystal Violet (Methyl Violet 10B), another basic triarylmethane dye, is frequently used for histological stains and for identifying Gram-positive bacteria. Crystal Violet Lactone, a derivative of Crystal Violet, is a basic thermochromic dye widely used as a security marker for various types of fuels. These three 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 UV-Vis regime at 540, 590, and 200 nm.

Various dyes are widely used in food, textile, and pharmaceutical industries. Dies are aromatic compounds containing ionizable groups. Methylene blue, crystal violet lactone, and crystal violet were separated on a Primesep D HPLC column. Method can be used for separation of other dyes and pigments that are basic and hydrophobic in nature.

Application Column
Newcrom B
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.
