pH 1, 70 °C

YMC-Triart C18, pH 1, 70 °C, Silica based C18, hybrid-silica based C18, The columns are stored in acetonitrile/water/TFA (10/90/1) 70 °C,  and the performance tested every 20 hours.

Test conditions
Column: 5 µm, 50 x 2.0 mm ID
Eluent: acetonitrile / water (60/40)
Flow rate: 0.2 ml/min
Temperature: 70 °C
Sample: butyl benzoate

YMC-TriArt C18 and C8 show great chemical stability due to the newly developed hybridsilica. Even under high pH or high temperature conditions, the lifetime of YMC-TriArt C18 and C8 is more than 10x greater than conventional reversed phase columns.
