The #VP4000 gives you the maximum flexibility in meeting the most demanding gas sampling
requirements. The pressure range is from vacuum to 4000psig (273bar), temperature range from
ambient to 300degC. Pathlength is stepwise variable from 0.5mm to 20mm. Four gas entry/exit ports
are provided with a fully swept, flow through sample pathway. Connections are by 1/16" tubing.
The gas ports are formed from the same block of material as the cell body. The result is maximum
structural integrity and corrosion resistance with no welds, no brazed joints. It is also possible
to alter the cell volume independently of the pathlength, should the cell volume be a critical
parameter; the volume is, of course, low in all cases (maximum volume is less than 3ml at maximum
pathlength). Windows are fully demountable and ZnS is the standard window material fitted for high
pressure operation. Other materials may be selected as desired. The cell is precisely temperature
controlled by an AABSPEC Digital Temperature Controller. The #VP4000 comes complete with an
adjustable mounting system and ready to install in the standard 2" FTIR sample slide. As an
option, AABSPEC Temperature Controlled Heated Transfer and Return Lines are available for
connection to high temperature gas systems. The AABSPEC #VP4000 is the most versatile and powerful
gas sampling facility for FTIR.
For combined high temperature and high pressure operation a version is available with Aabspec
patented Advanced Window Technology.
