Highlights

• Separation of 9 phenoxycarboxylic

acids with good resolution in a single run of 22 min.

Conditions: Column: ZORBAX SB-C18, 4.6 x 250 mm (Agilent Part No. 880975-902) Mobile Phase:

Injection: 10µl; UV: 245 nm; Flow: 1.0 mL / min.; 40°C

A= 20 mM KH t = 0 min, 10% B for 2 min t = 2 min, 10% to 65% B over 23 min t = 25 min, 65% B

2PO4

, B= ACN

• Improved peak shape on ZORBAX

StableBond results from more desirable silanol interactions.

• Separations on ZORBAX StableBond

show long-term reproducibility as a result of the sterically protected bonded phase.
