This is a high temperature, high pressure gas, solid and liquid cell designed for extreme condition spectroscopic
analysis. The accessory is capable of providing
temperatures up to 800C and permitting a range of pressures
from vacuum to 1000psi. It's configured to perform in
transmission, specular reflectance or decomposition modes.
The cell supports a 13mm disc assembly for transmission
analysis. Specular reflectance can be performed with a
simple interchange of the 13mm holder for a specular
baseplate assembly. The decomposition mode is attained
by repositioning the 13mm holder to permit placement of the
heated sample in a pan just below the optical beam .... as
gases evolve, the sample is analyzed.
Constructed from corrosion resistant stainless steel, the
cell is fitted with ZnSe outer jacket windows as standard.
A high stability dual read-out RS-232 temperature controller
accompanies the accessory to accurately monitor sample and
set point temperatures. The outer jacket windows can be
heated separately up to 200C to prevent condensation of
evolved materials. Multiple inlet/outlet ports are
incorporated in the design to allow purging and easy mixing
of gases for either continuous flow or static operation. The
cell volume is 80ml. Its pathlength is 30mm.
Built in safety features include a low voltage (30V) heating
system, thermal switches to prevent overheating, a burst
disc to prevent over pressurization, safety certified outer
jacket windows, and water cooled top and bottom blocks to
prevent heat transfer within the sample compartment while
allowing the accessible surfaces of the accessory to
maintain safe temperature.
The cell is suitable for liquid vapor studies, process gas
analysis, solid or solid-gas decomposition studies and
general extreme condition high temperature, high pressure
The order details provide for an accessory configured for
transmission and decomposition. As an option, the specular
reflectance upgrade can be ordered separately.
