• Features a “quick connect” for fast and simple
cartridge changes.
• Full glass/metal design with easy-to-read indicators.
To maintain the low bleed and high performance
of the MXT ®-1HT Sim Dist column, it is critical
to prevent oxygen from entering the column.
This can be achieved by routinely checking your
entire system for leaks and using a high-quality
gas purifier such as the Super-Clean™ SGT gas
filter. We also recommend the use of graphite
ferrules; Vespel ® or Vespel ®/graphite ferrules
will not withstand the high temperatures
required for this analysis.

Fast GC Temperature
Programming
GC Racer System*
✔ Save time and money by increasing throughput.
✔ Makes fast GC possible with any capillary GC column.
✔ Easy to operate and install—truly a “plug and play” accessory.
Fast temperature pro-
grams are commonly
used in gas chro-
matographic applica-
tions to speed up elu-
tion of high boiling
point compounds and
late eluters. The most
common gas chro-
matograph, the
Agilent 5890, has a
maximum temperature programmable rate of
70°C/min. The factory heating elements in the 5890
only allow for this maximum temperature program
rate to be maintained up to a temperature of 100°C.
For analysts trying to push temperature ramps as fast
as possible, this inhibited program rate leads to
longer analysis time and broader peaks. Now, using
the GC Racer auxilliary heating unit, temperature pro-
gram rates of 70°C/min. can be maintained up to
350°C (Figure 1).
The Restek GC Racer temperature programmer
consists of a resistive heating element placed on the
floor of the GC oven. The heating element is con-
nected to a controller that is plugged into the main
PC board of the GC.
When the GC Racer
programmer detects
that the factory heat-
ing elements are not
keeping up with the
programmed heating
rate, the heater is
brought into the cir-
cuit to augment the
heat being supplied
to the oven. The GC
Racer system will
maintain temperature program rates of 70°C/min.
up to 350°C and 60°C/min. to temperatures as high
as 450°C.
The simplicity of its components and installation
makes the GC Racer system a must have add-on
accessory for every 5890 GC. The auxilliary heater
design is similar to that of the original GC heater.
The heater plugs into the GC-Racer controller,
which plugs into the main PC board on the GC. The
only other connection needed is plugging the GC
Racer controller into a 110V standard grounded
wall outlet. At no time during the installation of the
GC Racer system does the column need to be
removed from the oven, or disconnected from the
detector or injection port.
The GC Racer system is a new tool in the quest for
high-speed GC. The speed of analysis that now can
be achieved and the ease of installation will lead to
direct savings of time and money by decreasing run
time and increasing sample throughput.

5890 as fast as a 6890!

5890 GC that increases the rate of temperature pro-
gramming. Using the GC Racer, the analysis of the
Polywax® 1000 reference material can be reduced
from over 50 minutes to less than 15 minutes by
temperature programming at 60°C/min. (Figure 2)!
The Restek MXT®-1HT Sim Dist column is the ideal
choice for high-temperature simulated distillation.
It meets all the criteria of ASTM Method D-6352
while providing low bleed and excellent peak
shape. Combining the MXT® -1HT Sim Dist column
with the GC Racer attachment significantly reduces
overall analysis time and greatly increases sample
throughput.
