Sequential injection lab-on-valve platform as a miniaturisation tool for solid phase extraction

Micro solid phase spectrophotometry in a sequential injection lab-on-valve platform for cadmium, zinc, and copper determination in freshwaters

“…The combination with the SI-LOV technique has proven to be advantageous with increased use and application [5].…”

On-line coupling of Micro-Extraction by Packed Sorbent with Sequential Injection Chromatography system for direct extraction and determination of betaxolol in human urine

“…This methodology is widely used for the analysis of trace level compounds in complex samples because of its potential for on-line sample extraction and automation [8]. Low pressure flow techniques represent a powerful tool for automation of both liquid and solid phase-based sample pretreatment due to their versatility, as it was discussed in several reviews [9][10][11]. Sequential Injection Chromatography (SIC) was introduced as a low pressure separation system in 2003 by Ša-tínský et al [12].…”

Flow Analysis: Looking Back and Forward

“…70 This circumvents drawbacks related to excessive backpressure and preferential pathways, also improving the analyte-sorbent interaction. Applications of solid-phase microextractions in flow systems encompass miniaturization, 71,72 bioanalysis, 72 and chemical speciation. 73 Emphasis has been given to selective materials, biosorbents, and nanomaterials, including modified magnetic nanoparticles.…”

“…73 Emphasis has been given to selective materials, biosorbents, and nanomaterials, including modified magnetic nanoparticles. 71,74 These materials are dispersed into the sample and further separated by means of an external magnet, thus favoring the analyte sorption and avoiding the increase in backpressure. On the other hand, monolithic columns and fused-core particles have been exploited for low-pressure chromatographic separations, especially in sequential injection systems (named as sequential injection chromatography).…”
