Dist columns the columns of choice forASTMD-6352-98 SimDist
analyses. Note that the demanding temperature conditions of simu-
lated distillation analysesmakeGC system integrity a prime con-
cern. It is imperative that theGC system be oxygen-free, to prevent
phase degradation andmaintain the highest level of chromato-
graphic performance.We strongly recommend using oxygen-free
carrier gas and routinely leak-testing your systemwith an electron-
ic leak detection device, such as our LeakDetective™ II electronic
leak detector (cat.# 20413), to ensure protection from oxygen.
