My Work
Using an ICP analyzer, I perform compositional analysis of our material products to ensure their quality. I also create new calibration curves, which serve as the "yardstick" for determining how much of each component is present. In the manufacturing process, analytical data plays a critically important role in certifying the quality of finished products at the time of shipment. It is a job that carries great responsibility, and at the same time, is very rewarding.
I love my job! — Memorable moments and what makes this work rewarding
During my training, I rotated through various departments and had the opportunity to communicate with people of all different ages. Even now that I am assigned to the analysis department, people greet me when we pass in the hallway and check in on me, making it easy to talk about work. I often feel that the connections I made during training continue to support me today, and that makes me truly happy.
Why I chose this company
I studied chemistry in university, but I had never learned about rare earths in school and had no opportunity to encounter rare earth elements. However, when I researched them, I discovered that rare earth elements are indispensable materials for cutting-edge industries in a wide range of fields. It was the hidden potential and the prospect of entering a new field that drew me to this company.
A story I can finally tell — my biggest mistake
When preparing a standard solution, which is fundamental to analysis work, I accidentally added the wrong solution. That single mistake meant I had to start the entire preparation over from scratch. To prevent repeating that error, I now make it a point to always cross-check the preparation sheet against the solution labels every time.
