UV-Vis Spectrum of Sulfadiazine
July 19, 2024
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 Separation of Antibiotics on Newcrom A Column
June 11, 2020
Antibiotics are widely used for treatment and prevention of bacterial infections. Various antibiotics, particularly those with a sulfanilamide structure, were separated in HPLC using mixed-mode columns with varying strengths of ion-pairing groups. Methanol can be used in the mobile phase on Newcrom A column. The antibiotics were resolved on both columns with a gradient mobile phase consisting of acetonitrile (ACN) or methanol (MeOH), water and sulfuric acid (H2SO4) buffer. UV detection at 275nm.

HPLC Separation of Antibiotics on Primesep 200 Column
June 6, 2020
Antibiotics are widely used for treatment and prevention of bacterial infections. Various antibiotics, particularly those with a sulfanilamide structure, were separated in HPLC using mixed-mode columns with varying strengths of ion-pairing groups. Primesep 200 has weak acidic ion-exchange pairing groups while Newcrom A has strong acidic ion-exchange groups. In addition, methanol can be used in the mobile phase on Newcrom A column. The antibiotics were resolved on both columns with a gradient mobile phase consisting of acetonitrile (ACN) or methanol (MeOH), water and sulfuric acid (H2SO4) buffer. UV detection at 275nm.
