Tailingpeaks andpoor responses for active compounds reveal surface activity in a column. In contrast,
thepeak shapes for 0.5ngof pyridine
(basic) and for 2,4-dinitrophenol (acidic),
onpage9, demonstrate theexcellent
inertness of Rxi™-5ms columns. Basic
and acidic compounds canbe analyzedon the same column, oftenunder the same conditions.
AnRxi
™
column’s inertness allows
analysisof active compounds at
levelsnot attainablewithother
manufacturers’columns.
