-190 to 250°C Liquid, Solid, Gas Transmission Cell
This is a -190 to 250°C Variable Temperature Cell which permits
transmission mode measurement of solid and liquid samples
with gas exchange capabilities across the face of a solid
sample. The cell consists of a vacuum outer jacket and a
cold finger that may be cooled with liquid refrigerant.
Sample cells are inserted into a block attached to the cold finger fitted with heaters to maintain precise temperature control. The external vacuum jacket windows are heated to prevent condensation at sub-ambient temperatures. The sealed or demountable liquid cell asssembly can be converted to a flow cell configuration with the appropriate attachment. Two fixed thermocouples are installed to monitor the temperature of the cell holder and the outer jacket window assembly. A spare thermocouple can be introduced to accurately monitor the sample temperature. The cell can be configured for UV-Vis and Fluorescence applications.
Options available include liquid sealed and demountable
cell configurations, solids cell, flow through cells, and a variety of window materials to assemble within these cells.
Scroll below for impression and order details.High pressure cells are available for liquid and gas samples analysis under high pressure (2000 psi and 5000 psi options). The useful temperature range for the high pressure cells is from -15°C to 180°C. The cells are fabricated from Stainless Steel for chemical resistance and durability with two 1/16” Stainless Steel flow tubes brazed to the cell body. A choice of fixed pathlengths include 0.5, 1.0, 2.0, 5.0 or 10mm. The transmission windows are permanently sealed in the cell housing using perfluoroelastomer o-rings. Available optical materials include UV Quartz, Sapphire and Zinc Selenide.
The high pressure cells can be used at ambient temperature when mounted on the standard 3" x 2" backplate. For heated or sub-ambient applications, the cells listed below can also be used with the 250°C Solid and Liquid Cell and the Transmission Cell Heating/Cooling Jacket.
Additional options represent a choice of temperature controllers for 110V or 220V operation with or without an RS-232, USB or RS-485 computer interface.
