Figure 9.15 presents an example of the in vivo measurements of the oxygen content in the arterial blood of dogs over a period of 10 h. The dots represent the batch gas analysis performed with a Nova Biomedical blood gas analyzer. The solid lines represent the analyses monitored by the instrument. Blood oxygen measurements were obtained continuously (not shown in the figure) about every 3 sec. Two different polymer solutions are shown. The measurements performed by the instrument are not affected by the presence of unmetabolized clots and/or anesthetics in the blood stream. Additionally, no deterioration of the signal was found after 10-h periods. 

The apphcation of derivative techniques to spectroscopy is very useful when signal overlap or interference exits and it offers a powerfnl tool for both qualitative and quantitative analysis of components in pharmacentical [11, 12], biomedical [13, 14] and food analysis [15, 16],... 

Very few, if any, recent biomedical publications describe the use of ion-impact mass spectrometry without the use of GC or some other separation method because most biological samples are chemically complex. The production of clean and useful El mass spectrometric signals requires the substance of interest to be very pure, and thus direct El experiments are usually confined to preliminary studies of highly purified biomolecules or to studies on the metabolism of pure materials. Two publications that describe direct El methods applicable to biochemical analysis and neuropharmaceutical studies are those of Costa et al. (1992) and Karminski-Zamola et al. (1995).
