LowestBleed624Available—AssuredGC/MSCompatibility
In addition to providing greater inertness and more accurate results for active compounds, the
Rxi®-624SilMS column offers higher temperature stability than any other column in its class (Table I,
Figure 3). Even thoughmost 624 columns provide adequate selectivity for polar compounds, poor ther-
mal stability results in stationary phase bleed that can reduce column lifetime, decrease detector sensi-
tivity, and interfere with the quantification of later eluting compounds. The highly effective stationary
phasebondingchemistryof theRxi®-624SilMScolumnensures extremely lowbleedup to320°C.While
other624 columns generate toomuchbleed tobeuseful for continuousmass specwork, theRxi®-624Sil
MS column is fully compatible with both quadrupole and ion trapmass spectrometers. In addition to
MS compatibility, higher thermal stability results inmore stable baselines, longer column lifetimes, and
improvedmethod reproducibility.
