Abstract
A spotting pin contains a probe solution. The spot volume is determined such that the probe solution may not intrude into the neighboring spot area. A spot volume is calculated from a pore ratio of the membrane and the spot volume. The spotting time is determined from the spot volume. An end of the spotting pin is contacted to the spot area of the biochemical analysis unit, and the probe solution is spotted to the membrane which is pressed into the spot area. Then the spotted region becomes extended gradually. When the predetermined spotting time has passed, the spotting pin is upheld. The spot volume of the prove solution becomes uniform, and the mixing of the probe solution is prevented between the neighboring spot areas.
