英文摘要:

      Objective To establish a method for evaluating handheld ATP fluorescence detector, and analyze the technical status of portable ATP fluorescence detector in the market. Methods The main performance indexes of the handheld ATP fluorescence detectors of the 10 common companies in the market were tested, including linear range, reproducibility, detection limit and attenuation rate. The test results were summarized and analyzed. Results There had difference of 10 companies in product testing capabilities. There was an order of magnitude difference for the linear range and the limit of detection. The precision were 7.3%-36.8% and the attenuation rate were 4.3%-81.5%. Finally, only 3 companies met the requirements of linearity, repeatability, detection limit and attenuation rate. Conclusion In order to meet the requirements on hygienic quality of different industries and apply the handheld ATP fluorescence detectors in more fields, the technical level of the products needs to be further improved.
