Surface water is generally coloured and turbid.When total phosphorus is analyzed by luminometer, the monitoring result will be somewhat high.

地面水一般带，采用光度法分析水样中总磷时，会使测结果偏高。

The luminometer accepts samples in 12 mm diameter test tubes with lengths ranging from 45 to 100 mm and 15 mL microcentrifuge tubes.

光度计使用45～100纳米的波长范围，12毫米直径的测试管和15毫升的微量离心管。
