Ph of milli-q water
WebThe Milli-Q ® EQ 7000 ultrapure water system is designed to produce consistent ultrapure water quality [resistivity 18.2 MΩ·cm @ 25 °C; total organic carbon (TOC) ≤ 5 ppb] that can be adapted to each user’s specific application requirements. WebAs said by bob1, pH for MilliQ should be around 6, usually a range of ±0.5. A given distillator/purification system uses to be quite constant in this value while there is no contamination. pH 8 is too high for MilliQ If there is no problem with the pHmeter... In these systems or in the reservoirs is quite easy that some bugs can proliferate.
