Manual emitter loading by using a 10 µl microliter syringe. (a) A drop of 1–2 µl at the tip of the needle is attached sideways to the activated emitter while strictly avoiding any other contact than to the liquid surface. (b) Gently retracting the needle by a movement to the side and up leaves the drop hanging like dew on a spider’s web. One can see that the liquid spreads out almost to the ends of the activated zone. After evaporation of the solvent the emitter is ready for insertion into the ion source.
