Conclusion
The automated titration system provides high precision in determining calcium levels in sea-water.
Supporting Evidence
- The titration system achieved a precision of 0.16% for calcium measurements.
- The system is capable of simultaneous titration of zinc using zincon as an indicator.
Takeaway
Scientists created a machine that can quickly and accurately measure calcium in ocean water, making it easier to test many samples.
Methodology
The system uses a Commodore PET 2001 computer for photometric titration, employing a modified Metrohm motor burette and a Brinkman PC/600 Colorimeter.
