Spectrocell has the capability to provide quartz or borosilicate glass cells that contain pure gases, or mixtures of pure gases, as specified by the user. Such cells are used as calibration standards or for other applications where a repeatable spectrum is desirable. The cell is evacuated down to 10 microns of pressure and then purged with the gas or gas mixture. The cell is then permanently sealed by fusing closed the filling aperture. The pressure of gas in the cell can generally be controlled very accurately from about 750 torr (.985 atmosphere) down to 50 to 60 Pa (about 0.5 torr). Exact pressures and specific repeatability are dependent upon the specific gas or gas mixture required. Once sealed closed, the lifetime of the cell is only limited by the permeability of the glass or quartz to the particular gases involved.
