摘要：<p>A method and a device are proposed for the injection of very small amounts of samples into cells (74) with the aid of a microcapillary (10). During the injection, a constant injection pressure of about 0.12 bar, provided by a pressurized cylinder (46) is applied to the microcapillary (10), which is reduced after the completion of the injection to a holding pressure of 0.02 bar until the next cell (64) is to be injected. A high-pressure (p1) supplied from another pressurized cylinder (44) serves for blowing out the microcapillary tip (12). A three-way valve (42) permits simple and rapid switching between the various pressures (p1, p2 and p3). Reproducible amounts of sample in the range from 10-11 ml to 10-13 ml can be injected reproducibly, simply and rapidly.</p>
