Inter-laboratory calibration

The laboratory operates to a set of standard operating procedures, which the client scan examine. The quality of our analytical approach is tested by conducting inter-laboratory comparisons. In the example right, a set of hydrolysed bone proteins from an artificial degradation experiment were analysed bling by the Institut für Rechtsmedizin Kiel and neaar. The slight offset from the 1=1 line indicates that in the case of HPLC the D-aspartic acid residue has a lower response factor than its L- counterpart.
