Resolution
- Add Triton X-100 to the rinse solution (0.1%). It has been found that this has helped along with increasing the rinse time.
- Decrease the concentration of the highest calibration standard and perform dilutions of the samples before analysis.
- If hydrofluoric acid is used decrease the concentration as much as possible or use another acid if feasible.
