摘要: Apparatus and method for sequential injection liquid-liquid extraction analysis. Under the control of a bidirectional precision pump, stream-selection valve, microprocessor, series liquid zones is built up in holding/mixing coil. The are transferred from coil to separation cell. After phase into an extract raffinate, withdrawn cell sent detector, which determines amount component was extracted sample by solvent. principal advantages this automated technology elimination need dynamic separation; on-line pre-extraction chemical conditioning; substantial reduction solvent, reagent, usage; similar waste generation.
