It is important that stability is evaluated under 100% aqueous conditions for an AUQA type C18 column because column
life becomes longer to increase a content of organic solvent in a mobile phase. Sunniest RP-AQUA can be used under
100% aqueous conditions from pH2 to pH8.
★
Sunniest RP-AQUA can be used under 100% aqueous conditions from pH 2 to pH 8. Sunniest RP-
AQUA is one of the most stable aqua type column.
