The LC/flame AAS has been employed for a number of years and Holak [5] used it to monitor the
separation of a number of mercury-containing drugs, mersalyl, thimerosal and phenyl mercuric borate.
Suzuki et al. [6] used the technique to identify the heavy metals bound to isoproteins extracted from
liver tissue. Robinson and Boothe [7] used the selectivity of the LC/AA system to monitor the alkyl
lead compounds in sea water and Messman and Rains [8] separated five alkyl leads, tetramethyl lead
(TML), trimethylethyl lead (TMEL), dimethyldiethyl lead (DMDEL), methyltriethyl lead (MTEL) and
tetraethyl lead (TEL) in gasoline. An example of their separation is shown in Figure 10.3.
