Handling of Activated Emitters

Note To apply a solution of the analyte, the emitter can either be dipped into, or alternatively, a drop of 1-2 pi can be transferred onto the emitter by means of a microliter syringe. [46] The latter method exhibits better reproducibility and avoids contamination of the emitter holders. Special micromanipulators are available to handle the syringe, [15] but a skilled operator with some exercise can accomplish it manually.
