Stable Trap Even for Large Injection Volumes

The Shim-pack MAYI-ODS column provides stable component
recovery rates and protein removal, even when injecting large
volumes. Even when 500 μL of blood plasma was directly injected,
a high recovery rate was obtained and no peak distortion was
observed.
Conditions
Samples : Indomethacin added Blood plasma
Sample solution: 0.1% phosphoric acid and acetonitrile
mixture (95:5)
Dilution: 8 times
Detection : UV 315 nm

Comparison Data for Injecting 100, 200, and 500 μL
