| Manual | During the determination of amino acids and acylcarnitines within the scope of newborn screening the internal standard is used as an individual calibrator for each sample, so matrix effects are reduced to a minimum. The internal standard is added directly to the dried blood spot disk and is prepared and analysed together with the blood sample. |

| Reconstitution | Remove the seal and rubber stopper from the vial. Reconstitute the lyophilised internal standard with exactly 50 ml of extraction buffer (order no. 57008): For this purpose add 5 ml of extraction buffer into the vial. Replace the stopper and allow to sit for 5 to 10 min at room temperature. Swirl the vial to dissolve the contents until homogeneity. Then transfer the content of the vial into a 50 ml volumetric flask. Wash the vial twice with 5 ml extraction buffer and combine the solutions. Dilute the volumetric flask with extraction buffer to exactly 50 ml and swirl the flask. |
