Conclusion
The IQAS discrete analyser provides improved precision, accuracy, and efficiency for routine water quality analysis compared to traditional methods.
Supporting Evidence
- The IQAS analyser showed significantly lower carry-over rates compared to traditional autoanalysers.
- Detection limits for the IQAS were an order of magnitude better than those of the autoanalysers.
- The precision of the IQAS was improved through method modifications, achieving a CV of 0.4 at 75% full scale.
- Results from the IQAS were closely aligned with those from standard methods, indicating high accuracy.
Takeaway
The IQAS machine helps test water quality faster and more accurately than older machines, making it easier for scientists to check if water is safe.
Methodology
The study involved assessing the performance of the IQAS analyser by comparing its results with standard procedures and analyzing various water quality parameters.
Limitations
The IQAS cannot handle on-line phase separation or distillation methods.
