direct injection nebulizer (DIN)

The direct injection nebulizer (DIN) is a microconcentric pneumatic nebulizer with no spray chamber for sample introduction to the inductively coupled plasma (ICP). The DIN is placed directly in the torch, taking the place of the injector and nebulises the liquid sample directly into the central analyte channel of the ICP. Because of the limited solvent load capacity of the plasma, the DIN must be operated at low flow rates between 30-100 µl/min.
