摘要: The needle trap device (NTD) is an extraction that contains a sorbent inside small needle, through which fluid can be actively drawn into and out of by gas-tight syringe or pump, analytes introduced passively to the diffusion. (NT) potentially solventless sampling technique/sample preparation introduction device. Both fluid-borne particles trapped then adsorbed are desorbed in inlet analytical instrument for identification quantification. may either gaseous liquid. objectives this critical review summarize theory process both active passive time-average modes addition outlining evolution technology main applications.
