An instrument in which a beam of electrons or other radiation is focused onto a minute area of a sample and the resulting secondary radiation (usually X-ray fluorescence) is analyzed to yield chemical information.
- Until recently, ion microprobes could only analyze dozens of such sub-grains at one time and so were able to deduce only the average properties of a sample.
- In view of these complexities, further U-Pb geochronology was carried out using the ion microprobe.
- Pressure in the xylem elements, monitored with a pressure microprobe, changed from the initial pressure at the time of pressure step to the new steady pressure after some time.
