The HPLC
chromatogram of Citrus sinensis root extract showed a total of five polyphenolic compounds; chlorogenic acid, quercetin, rutin, mandalic acid and hydroxy benzoic acid that were identified through comparison with standard
chromatogram of eight standard antioxidants (Fig.
There are pairs of distinguishing peaks of n-alkanes and n-1-olefins in the GC-FID
chromatograms of MD.
Chromatogram obtained after the injection of 1.0 [micro]L of the transesterification reaction diluted in heptane (1:1000) using Nb[Cl.sub.5] as a catalyst containing methyl palmitate, (1), methyl stearate (2), methyl oleate (3), methyl linoleate (4) and methyl linolenate (5).
This term refers to a raised "baseline hump" in
chromatograms composed by a mixture of compounds unresolved by capillary columns [17].
The
chromatograms have been labeled (a) and (b) for this letter.
Figure 7 shows
chromatograms of the reaction mixtures of Boc-Gly-L-Asp at 130[degrees]C for varying reaction times.

Exp 1 and Exp 2 are the closest to the worst: Exp 1 is characterized by small areas of the peaks located both in the first (negative scores on [PC.sub.2]) and in the second (negative scores on [PC.sub.1]) part of the
chromatogram. Exp 8 and Exp 4 are the best ones for what regards [PC.sub.1] (larger areas for the peaks of the second part of the
chromatogram), while Exp 7 is the best one for what regards the peaks eluting in the first half of the
chromatogram.

Three
chromatograms of the heat induced methyl linolenate sample are shown in Fig 2.
HPLC is used as the primary method for HbA1c analysis in many laboratories in New Zealand and an abnormal
chromatogram trace does not give specific result of the precise variant, but can elucidate different haemoglobins by means of their physicochemical characteristics, in the context of clinical and family history, ethnic origin, blood count and blood film (4).
