Palintest paired up with CEBAS CSIC in Spain, Campden BRI in the UK, and SGS in China to get external validation of the sensor products against laboratory methods such as titration and HPLC.
Why are accurate measurements important?
In the fresh produce washing industry, the best way to ensure that the produce is free of pathogens is to monitor the disinfectant level of the water. Accuracy describes how close to the true value your measurement method result is. An inaccurate measurement result will give you a false view of the disinfectant level in the wash water.
Palintest’s sensor technology has been proven in fresh produce washing applications to be more accurate than the traditional drop count kit, and also comparable in terms of accuracy to the laboratory methods.
With each partner, Palintest’s sensor technology was tested at the same time as the traditional industry method of drop count kits, and either the standard laboratory titration or the laboratory high-performance liquid chromatography (HPLC) method.
Each method was used to measure produce wash water with differing disinfectant levels, and the average results for each method compared to ensure that the sensor methodology was comparable to the lab methods, and had improved accuracy and precision compared to the drop count method.
Across all concentrations of disinfectants, Palintest’s sensor technology produces measurements with a similar degree of accuracy and precision to the laboratory methods.
Accuracy in disinfectant measurement is key to keeping customers safe and managing cost efficienciesOutcomes
