Enhancement of Instrument Response

Enhancement of detector performance by FIA is exemplified by increase in sensitivity, ability to distinguish between different species and by conversion of nondetectable species into detectable ones. 

The on-line microcolumn technique allowing improvement of the detection limit of atomic absorption and atomic emission spectroscopy by 

Indirect determination of sulfate by AAS is an example of instrument enhancement achieved in a novel way. When developing a conversion method for sulfate, based on the formation of BaS04, A. J. Rasmussen, a graduate student at Chemistry Department A, observed that the quan- 

The term hyphenation was proposed by the late Thomas Hirschfeld [8.4] to emphasize a novel source of information obtained by a suitable combination of two mutually independent instrument responses with the purpose of enhancing tthe selectivity of response not attainable by a single instrument or even by the two individual instruments operated separately, but achieveable when these two instruments are appropriately linked— by a hyphen. Examples of well-known suitable combinations are GC-MS
