Tomaintain the low bleed and high performance of theMXT
®
-
1HTSimDist column, it is critical to prevent oxygen from
entering the column. This can be achieved by checking your
entire system for leaks before and after each thermal cycle.We
also recommend the use of graphite ferrules; Vespel
®
or
Vespel
®
/graphite ferruleswill not withstand the high tempera-
tures required for this analysis as theymay crack.
As part of cost reduction efforts, many laboratories try to reduce
individual analysis time in the interest of increasing overall
throughput. High-temperature simulated distillation analyses
can take as long as an hour, especiallywhen samples contain
hydrocarbons up toC110.An effective technique to reduce
analysis time is to use rapid temperature programming.
Unfortunately, most GC systems have temperature-program-
ming limitations of 20
°
C to 25
°
C/min. SomeGCs can heat
quickly at low temperatures, but cannot maintain the fast rate at
higher temperatures, like those needed for SimDist. To over-
come these limitations, Restek offers theGCRacer, an attach-
ment to yourAgilent 5890AGC and 5890 Series II, that
increases the rate of temperature programming. Using theGC
Racer, the analysis of the Polywax
®
1000 referencematerial
can be reduced from over 50minutes to less than 15minutes
by temperature programming at 60
°
C/min.

TheRestekMXT
®
-1HTSimDist column is the ideal choice for
high-temperature simulated distillation. It meets all the criteria
ofASTMMethodD-6352while providing low bleed, excellent
peak shape and resolution. Combining theMXT
®
-1HTSim
Dist columnwith theGCRacer attachment significantly
reduces overall analysis time and greatly increases sample
throughput.
