General description
LpDNPH S10L Cartridge is employed for trapping carbonyls on a high purity silica adsorbent coated with 2,4-dinitrophenylhydrazine, then converted to hydrazone derivatives. The derivatives are eluted from the cartridge in acetonitrile and are analyzed by HPLC.
The S10L cartridges features a reversible design and is for analysts who prefer shorter dimensions and does not require an adaptor for sampling. The cartridge is eluted by connecting to a syringe barrel (empty SPE cartridge) that acts as a reservoir for gravity-fed elution solvent. Meets EPA TO-11A requirements.

Guten Tag, können Sie mir bitte mitteilen, zu welchem Massenanteil die Kartuschen 505361-U mit DNPH beschichtet sind? Ich kann der Produktbeschreibung nur entnehmen, dass diese mit 350 mg Silicagel gefüllt sind. Wie viel % ist davon DNPH?
