Stewart, et al (1) have described a method for the analysis of trace organic compounds in the blood. An absorption cell has been designed which is particularly useful in this type of work and which may be suited to other applications as well. The cell is easily assembled, is less subject to leakage than most infrared cells, and solution transfer losses are minimized by its use.
