Sample Application as Spots

The simplest technique to apply samples as spots is to use a fixed volume pipette that fills by capillary action and delivers its content when it touches the layer. Variable volumes can be applied with a syringe, preferably one with micrometer control. Instruments for sample application should ensure two things: first, that the spots are precisely positioned and second, that the layer is not damaged during application. The Camag Nanomat is a mechanized spotting device using fixed volume glass capillaries, which are lowered onto the layer with reproducible contact pressure (Figure 1). The exact position of the spot is mechanically controlled. An instrument designed for the use of microlitre syringes is the Desaga PS 01 Sample Applicator.
