The 0.53mmMXT
®
-BiodieselTG columns are an innovative alternative to using a 0.32mm col-
umn coupled to a 0.53mm retention gap. Restek applied the Integra-Gap
™
integrated retention
gap technology to the 0.53mm
MXT

-BiodieselTG columns, elimi-
nating the column coupling. These
100% leak-proof columns feature
a built-in retention gap, reducing
the risk of peak broadening and
tailing, and guaranteeing the user
many analyseswithout downtime.
