In this work we demonstrated a facile method for in situ fabrication of the Fe 3+ 1,3,5-benzenetricarboxylic acid (BTC) metalorganic coordination polymer gel in a capillary, which was efficiently applied to the online enrichment of trace polycyclic aromatic hydrocarbons (PAHs) in environmental water and amphetamines drugs in urine. A facile method for in situ fabrication of the organometallic gels in a capillary for online enrichment of trace analytes has been presented.
