Sample Preparation

Typically samples are physically incorporated into two conductive electrodes (usually either carbon or silver) between which a high-voltage electric spark is produced, ionizing the material at the tips of the electrodes. If metals are being analyzed the sample may serve as an electrode.

Famous quotes containing the words sample and/or preparation:

    The present war having so long cut off all communication with Great-Britain, we are not able to make a fair estimate of the state of science in that country. The spirit in which she wages war is the only sample before our eyes, and that does not seem the legitimate offspring either of science or of civilization.
    Thomas Jefferson (1743–1826)

    With memory set smarting like a reopened wound, a man’s past is not simply a dead history, an outworn preparation of the present: it is not a repented error shaken loose from the life: it is a still quivering part of himself, bringing shudders and bitter flavours and the tinglings of a merited shame.
    George Eliot [Mary Ann (or Marian)
