(A) On-line flow through sampling analysis with prederivatized amino acids 5 mM serine (S), GABA, glutamate (E), aspartate (D), and ortho-phosphoserine (OPS), internal standard) with temporal resolution of 25 s. Separation buffer: 20 mM borate, 10 mM SDS, pH 9.2, injection time 0.5 s, 500 V/cm separation voltage. The mi-cromixer chip was used with 1 inlet for prederivatized amino acids.
