In this work, analytical performance of a laboratory built double membrane desolvator (DMD) was studies using perfluoroalkoxy (PFA) nebulizer and microconcentirc nebulizer (MCN) in inductively coupled plasma atomic emission spectrometry. Compared with MCN, PFA nebulizer coupled to DMD showed similar analytical sensitivity for aqueous solution and better sensitivity for isopropyl alcohol. Since PFA resisted various acids, HCI, $H_2SO_4$ and HF solution were analyzed with less than 2% RSD. Rinse-out time for the signal reduction to 1% was obtained to be 35 s for PFA but about 45 s for MCN.
