Rxi™ columnsweredeveloped fromRestek’sunwaveringpassion
to create capillary columns superior toall others.
Ourmissionwas to invent acolumn that had the
highest inertness
, the
lowestbleed
, and the
greatest reproducibility
in
everymeasurable facet of performance. Theend result of ourworkhad tobeclearlyobservableasbetter thananycolumn
used in thepast, bychromatographers inany laboratoryaround theworld.
Clearlydifferentandabsolutely thebest
were
thenon-negotiablegoalsof our research.
Toachieve theseaims,wehired theworld’sbestpolymer chemists andbuilt anew, fully-equipped facility. Theproducts this
team isdeveloping, Rxi™columns, genuinelyhaveexceededour goals. The first of thesenewcolumns, Rxi™-1ms andRxi™-5ms
columns, areabsolutely thebest on themarket today. Howare theydifferent?Until now, powerful newMS systemshavebeen
capableof analyzing low levelsof activecompounds, but column limitationshavekept analysts fromusing this ability to their
advantage. Now,withRxi™columns, youcanchromatograph sub-nanogram levelsof acidicandbasiccompounds inone
analysis.Other columnsexhibitpeak tailing for theseactivecompounds, causing integrationerrors andproducingnon-linear
calibrationcurves, and thereby limiting low-level analysis.OnlyRxi™ technologywill enableyou to reliablychromatograph
bothacidicandbasiccompounds atpreviouslyunattainable trace levels.
