applicable to all analytes in all sample types. Therefore, there is a need to become
familiar with different analytical techniques and to become qualified to combine the
individual techniques and approaches for a successful detection and determination
according to the varying chemical properties of the numerous analytes. This is
roughly illustrated in Fig. 1.3.
General Note
To analyse organic substances with high sensitivity and accuracy, a suitable
analytical approach needs to be adopted to the chemical properties of the
analytes. An universal method does not exist.
