of pyruvic acid with triple quadrupole LC
The HPLC chromatogram
of compounds that were identified in stem of Citrus sinensis have been shown in Fig.
The GC-FID and GC-SCD chromatograms
of distillates of KH are shown in Figures 2-7 together with chromatograms
of the corresponding hydrotreated oils.
obtained after the injection of 1.0 [micro]L of standard stock solution containing the palmitate esters of methyl (1), methyl stearate (2), methyl oleate (3), methyl linoleate (4) and methyl linolenate (5).

Caption: Figure 1: (a) Questioned Enbrel chromatogram
included in Figure 3 panel b of Miranda-Hernandez et al.
(a) gave only one peak, but (b) gave two peaks, in which the longer retention time peak was caused by the lower molecular weight products.

As it can be observed from the figures, the first PC is mainly related to the behavior of the peaks eluting in the second part of the chromatogram
(long retention times), almost all characterized by large positive loadings; an opposite behavior is observed for [PC.sub.2], which shows large negative loadings of the peaks belonging to the first part of the chromatogram
(short retention times).

As an abnormal chromatogram
was detected, it suggests there may be problems with the measurement on the primary analyser (Bio Rad Variant).
