Quality assurance:
To check the measurement system (test reagents, meas-
urement device, and handling) we recommended to use
®
Spectroquant CombiCheck 30, Cat.No. 114677.
Use 10 ml R-1 instead of the sample.
Ready-for-use manganese standard solution Certipur
Cat.No. 119789, concentration 1000 mg/l Mn, can also be
used after diluting accordingly.
To check for sample-dependent effects the use of addition
solutions (e.g. in CombiCheck 30) is highly recommended.
Use 10 ml sample + 0.1 ml R-2.
