Among non-LAL based assays, GC/MS willpower aims to target lipid A and its three-hydroxy fatty acid molecules. Some scientific tests advise that GC/MS Examination can be clinically productive if its sensitivity and accuracy ended up markedly improved [nine,forty six]. A quantitative method was produced by fluorescence labeling of three-hydroxy fatty acid, but a complex course of action with preparative HPLC is necessary [47].
