Abstract
A liquid cell for IRS comprising a rod-shaped crystal having a cylindrical sampling surface and integral conical end portions forming end entrance and exit faces for a radiation beam. The center of the end faces are masked. All radiation entering the entrance face internally reflects from the conical surface and propagates down the IRE by multiple internal reflections from the cylindrical sampling surface. The IRE can be sealed into a trough or flow-through housing for the liquid sample. The seals are at insensitive regions of the IRE.
