High Temperature Sample Cell Option
The 5100 HD oven enclosure is capable of maintaining temperatures up to 150C.
Some applications demand a high oven temperature to prevent condensation or
plugging. For these situations, a special high temperature cell was designed. The
main purpose of this sample cell is to thermally isolate the sensitive components
(GRIN lens, detector) from these temperatures. This is accomplished through the
use of a window and spool piece at the top of the sample cell. For some applications
the spool piece may be purged with dry air or inert gas (e.g. to remove background
moisture). The rest of the analyzer remains the same as for a standard sample cell.
Space-Coupled Option
This option is used for certain application (e.g. O2 measurement) where fiber optics
are not the best approach. Instead of fibers, conventional optical components are used
to direct the laser light through the sample cell. The reference cell is in series optically
with the sample cell, creating a combined path. The reference cell absorption is then
subtracted from the total to get the sample concentration. The sample system and
electronics for this option are the same as for the standard analyzer.
