In continuation of earlier work on the detection of δ-aminolevulinic acid (ALA)-induced protoporphyrin IX (PPIX) in blood and serum both the extraction method and the analysis were improved considerably. Liquid chromatography (LC) analysis was transferred from capillary equipment to an analytical workflow reducing the experiment time from several hours to 10 min. These promising results enable LC coupling to modern mass spectrometers which boosts the sensitivity about 100-fold.Als Fortsetzung von Arbeiten zur Bestimmung von δ-Aminolävulinsäure (ALA)-induziertem Protoporphyrin IX (PPIX) in Blut und Serum wurden sowohl die Extraktionsmethode als auch die Analysis wesentlich verbessert. Von Kapillar-Flüssigchromatographie wurde auf eine höhere...
