Summary
Chromatography-based techniques for automating trace component determination in biological matrices are examined. Once samples are brought into solution or extracted, a range of fluid handling systems may be applied to automate most analyses. However, extraction remains a limiting step and the development costs and time required to automate any method successfully must be carefully considered. These and other factors which will influence the decision to automate any analytical method are explored and the problems of trace analysis discussed. Methods based on solid-phase extraction, dialysis and column switching approaches are evaluated in detail and interesting approaches described.
