Author Information
Author(s): Celio Pasquini, Lourival C. de Faria
Primary Institution: Instituto de Quimica- Universidade Estadual de Campinas
Hypothesis
The study aims to develop an operator-free flow injection analyser capable of processing up to 40 samples.
Conclusion
The constructed analyser demonstrated high performance with a relative standard deviation of 0.5% for Cr(VI) determination.
Supporting Evidence
- The analyser can run up to 40 samples without operator intervention.
- The relative standard deviation for Cr(VI) determination was found to be 0.5%.
- The device was built using low-cost components and can be controlled by digital signals.
Takeaway
The researchers built a machine that can test many samples without needing a person to operate it, making it easier and faster to get results.
Methodology
The analyser was constructed using a microcomputer to control a sample introduction device and an adapted auto-sampler.
Limitations
The study does not discuss potential limitations of the analyser's design or performance.
