Product details
Our salts in HPLC grade are excellent for use as buffers in HPLC analysis, with absorption tested at various wavelengths for all salts. Buffer solutions prepared from these are typically utilized in reverse-phase high-performance liquid chromatography (RP-HPLC) when the sample forms acidic (oxonium ions (H3O+)) or basic (hydroxide ions (OH−)) groups. Buffers mitigate the impact of oxonium and hydroxide ions, thus reducing pH fluctuations.
