Incorporating a Separation Into a Flow Injection Analysis

Dialysis and gaseous diffusion are accomplished by placing a semipermeable membrane between the carrier stream containing the sample and an acceptor stream. Shown here is a flow injection manifold incorporating a semipermeable membrane. The smaller green solutes can pass through the … Continue reading

Liquid-Liquid Extractions

Shown here is an illustration outlining the progress of a traditional liquid–liquid extraction (LLE) using two identical extractions of a single sample with fresh portions of the extractant. The numbers give the fraction of analyte and interferent in each phase … Continue reading

Liquid-Liquid Extraction

Illustration showing a liquid–liquid extraction using a separatory funnel: (a) before the extraction, 100% of the analyte is in phase 1; (b) after the extraction, most of the analyte is in phase 2, although some analyte remains in phase 1. … Continue reading
