    摘要： The present invention provides a method for measuring and calibrating sample injection volume or mobile phase delivery rate of any type of micropumps or their integrated systems by using the direct proportion of the total activity (or mass) to the delivery rate (or volume) of a radiochemical nuclide with known activity in a certain time period. Also, the present invention may adjust the range of measurement and calibration from micro-liter (μL) to pico-liter (pL) or from μL/min to pL/min by selecting nuclide species and their concentrations from different liquid calibration radiation sources.

    摘要翻译： 本发明提供了一种用于通过使用总活度（或质量）与总活性（或​​体积）的直接比例相比，来测量和校准任何类型的微型泵或其集成系统的样品进样体积或流动相递送速率的方法， 放射化学核素在一定时间内具有已知活性。 此外，本发明可以通过从不同的液体校准辐射源中选择核素种类及其浓度，将测量和校准的范围从微升（μL）调整到微升（pL）或从muL / min调节到pL / min。
