Earlier we’d blogged about quality standardization in waste water treatment facilities’ labs. This EPA handbook goes even deeper and provides you with guidelines for analytical quality control in the waste water labs. Note that the handbook is useful both for wastewater as well as for water labs. One particular area of concern is the care and maintenance of the analytical balance. This is important since the accuracy of all data in the analytical lab will depend on the accuracy of the balance. The handbook lists specific do’s and don’ts that will aid you in maintaining your balances. The information in this handbook is still valid even though the document is slightly dated (1979 to be precise). Thus, you will find mentions of the balance beam, the predecessor of the modern analytical balance. Those can be safely ignored unless you still have one of them in service!
