10cm Vapor Gas Multi-sampler with sheathed Iron Constantan 304SS type J thermocouple, 220v, 250w heater system, Swagelok® vacuum valve, thermocouple port, injection port heatable to 200o C, heated windows to prevent fogging, KCl windows, 303SS body.
This heated cell can be configured as a gas cell or for vaporizing samples that are normally solids or liquids at room temperature. Configured for gas sampling, the cell incorporates 2 valves, an inlet and an outlet, that enable flowing gas samples through the cell.
In its solid and liquid vaporization configuration, the cell has an outlet needle valve from which a vacuum can be pulled and two sample inlets.One inlet is a needle septa injection port on the top of the cell which is similar to the type used in gas chromatography. There is a second inlet in the form of a side port for inserting solid samples, which also doubles as the thermocouple port. Using the side port eliminates the need to recheck vacuum seals whenever the cell is opened to insert solid samples. The 220v, 250w heating jacket extends over the end of the cell so that both the cell body and the optics are heated, and allows operation at temperatures up to 200o C. Condensation on the optics is minimized by heating them to the same temperature as the sample chamber. A type J iron constantan thermocouple is provided with plugs which are compatible with the optional temperature controller. The cell body is type 304 stainless steel and an assortment of seals is provided (silicon rubber, viton and PTFE).The cell comes standard with 47mmx6mm KCl windows. The clear aperture is 39mm.
