PFA LC Microflow Nebulizers, 150 µm I.D. with zero dead volume, are made from high purity, HF resistant PFA. Included are CTFE Union fittings (N8152478), a PTFE connection line (N8152479) and a capillary tube (N8152480). The sample uptake rate is controlled by the diameter of the external capillary or probe. MicroFlow nebulizers are resistant to clogging, reliably self-aspirated or pumped to produce a fine aerosol for high transport efficiency and high sensitivity.
