For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Method for Dansyl Amino Acids on Newcrom R1 by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Dansyl-DL-leucine cyclohexylammonium salt, Dansyl-DL-norleucine cyclohexylammonium salt, Dansyl-DL-norvaline piperidinium salt, Dansyl-DL-phenylalanine cyclohexylammonium salt, Dansyl-DL-valine cyclohexylammonium salt, Dansyl-DL-α-amino-n-butyric acid, Dansyl-L-methionine cyclohexylammonium salt, Dansyl-gamma-aminobutyric cyclohexylammonium salt 

Dansyl Amino Acids are created when dansyl chloride reacts with amino acids, peptides, or protein. It is used for identification and quantification of the previously mentioned compounds through Thin Layer Chromatography (TLC) and High-Performance-Liquid-Chromatography (HPLC) in a process called dansylation.

Dansyl-DL-leucine cyclohexylammonium salt, Dansyl-DL-norleucine cyclohexylammonium salt, Dansyl-DL-norvaline piperidinium salt, Dansyl-DL-phenylalanine cyclohexylammonium salt, Dansyl-DL-valine cyclohexylammonium salt, Dansyl-DL-α-amino-n-butyric acid, Dansyl-L-methionine cyclohexylammonium salt, Dansyl-gamma-aminobutyric cyclohexylammonium salt can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes a gradient method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a phosphoric acid buffer. Detection is performed using UV.
