INCREASED STABILITY OF DISCOVERY BIO WIDE PORE C5 OVER CONVENTIONAL C4
 

After 25,000 column volumes (222 gradient cycles) were passed through the column, the Discovery BIO Wide Pore C5 showed very little change in efficiency. The competitive C4 column showed a significant loss of efficiency, as much as 50%.
 

Column: Discovery BIO Wide Pore C5, 5cm x 4.6mm, 5µm; Mobile Phase: (A) 0.1% TFA in H2O : MeCN (95:5), (B) 0.1% TFA in H2O : MeCN (25:75); Flow Rate: 2mL/min; Temp: 35°C; Detection: 220nm; Injection: 5µL; Sample: Protein/Peptide Test Mix; Gradient: 0-20% B in 20 min

STABILITY OF DISCOVERY BIO WIDE PORE C5 AT pH 8.0
 

Retention times of the sample components remained constant after 14,000 bed volumes were passed through the column.
 

Column: Discovery BIO Wide Pore C5, 5cm x 4.6mm, 5µm; Mobile Phase: 25mM potassium phosphate, pH 8 : MeOH (95:5); Flow rate: 2mL/min; Temp: 35°C; Detection: 254nm

UNDETECTABLE LC/MS BLEED
 

LC/MS Bleed Analysis on Discovery BIO Wide Pore C5
Column: Discovery BIO Wide Pore C5, 15cm x 4.6mm, 3µm; Mobile Phase: (A) 0.1% TFA in H2O, (B) 0.1% TFA in MeOH; Flow Rate: 1mL/min; Temp: 30°C; Gradient: 0-100% B in 15 min, hold for 5 min, then back to 0% B for 10 min
 

No TIC baseline rise relative to blank run (gradient run w/o column)
