摘要
样品浓度影响到微生物膜上菌种的活性。在仪器的适用范围内,标准可以按3个级别来确定,即5 mg/L,10 mg/L,20 mg/L。为了获得样品的准确浓度,可在这3个浓度范围内分别取一至两点进行点控,灵敏度下降表明,应该更换微生物膜。样品的精密度变化可以作为更换管路的一个依据。
The concentration of sample affects the activity of strains on the microbial film. The standard could be divided into 3 levels, 5mg/l, 10mg/l and 20mg/l, in the application range of the instrument. To get the accurate concentration of the sample, the one or two points could be selected for the point control in the range of the three levels. The decrease of sensitivity means the microbial film should be replaced. The precision change of sample is a basis for the pipeline replacement.
