Any feedback, precautions or advice? Mass Spectrometry. Ideal for the analysis of aldehydes and ketones as DNPH derivatives. Well-balanced retention profile for better detection and integration of large, multiclass analyte lists. Ideal for applications that require highly aqueous mobile phases, such as organic acids and water-soluble vitamins. A polar group assists in deactivating surface silanols and contributes to unique separation selectivities for acids, bases, zwitterions, and other polar compounds.
