Comparison of MiraMist® PTFE nebulizer and a standard glass concentric nebulizer performance in analysis of polydimethylsiloxane (PDMS) by Evaporative Light Scattering Detector (ELSD). The MiraMist® nebulizer was seen to perform significantly better at low flow rates and also demonstrated a significantly improved lifetime. Sensitivity of various polymer chains was seen to decrease by approximately 90% over the course of two weeks of run time with the glass concentric nebulizer. However, after nearly 3 months of analysis with the MiraMist® little to no sensitivity loss was observed indicating the PTFE nebulizer is significantly less prone to clogging during the analysis of polymer chains.
