ABSTRACT:
A high pressure optical cell for spectrometry is provided. The cell includes a monolithic crystal having a longitudinal bore within. The cell also includes a sheath/housing for holding monolithic crystal and sample introduction tubes. The sample introduction tubes can be microwelded. Compression ferrules or O-rings are used for sealing. A method for making the cell is also provided. A spectroscopic analyzer having a high-pressure optical cell is further provided.
