Flow Injection Tutorial

Sorbent extraction has been automated by Sequential Injection in two ways:

1) using prepacked microcolumns or cartridges as outlined on the previous slide.

2) in BI renewable column format, as described in Chapter 3.

Renewable microcolumns are accommodated within the LOV module and can be automatically packed and removed as needed.

Since successful method development in renewable or traditional column format depends on understanding the underlying chemical reactions, the reader is encouraged to consult the following reviews that are helpful in optimizing conditions for trace metal analysis in sea and fresh water (Miró 2008, Motomizu and Sakai 2008). For manual methodology of SPE for assay of a wide range of organic compounds, the monograph (Fritz 1999) offers valuable information.
