ACME™ Biphenyl

ACME™ BIPHENYL

GET ALTERNATE SELECTIVITY AND BETTER RESOLUTION FOR REVERSED-PHASE ANALYSIS USING ACME BIPHENYL

ACME Biphenyl Key Features and Benefits:
• Reversed-phase retention similar to C18 columns
• Compatible with 100% aqueous mobile phases
• Orthogonal selectivity when compared to C18 columns
• Ideal for compounds that contain an aromatic (phenyl) group and exhibit π-π interaction
• Benzodiazepines, steroids, drugs of abuse (opiates, opioids, illicit drugs, tricyclic antidepressants, etc.), moderately polar analytes, i.e., alkenes, ketones, nitriles, etc.
• All HPLC and LC-MS applications where a C18 column does not provide sufficient selectivity
