Our probe lab has been recently upgraded with a new JEOL JXA8230 5-WDS electron microprobe.

Exciting new features, including but not limited to:

1) 5 WDS, which would cut the counting time into halves;

2) Improved EDS system detecting B~U;

2) Fully integrated WDS and EDS system, which enables major elements measurements by EDS, trace by WDS to save even more time;

3) Integrated imaging package, which will better record the probed locations and make  “mapping with WDS” become possible;

4) Optional Xenon detector and special spectrometer with smaller Rowland circle which enhances the count rates for metals;

5) Stage holder with greater capacities and tolerance;
