HPLC enables users to view the LA1c as a distinct peak in the chromatogram
in TIC, which is labor-intensive, and the relatively low responding ions from the complex chemical background in full-scan mass chromatograms
is difficult to be detected and identified by HPLC-MS.
On m/z 217 mass chromatograms
pregnanes were recorded in all the oil shale samples.
Figures 2 and 3 showed different of peak area of oligosaccharides determined from chromatograms
at different sonication time for respective samples as shown in Table 1.
A skilled researcher can detect many more compounds in an oil sample, creating finely detailed gas chromatograms
with more peaks that can be mined for more information.
Unlabeled and undated chromatograms
with no unique identifiers such as your lot number and the date of analysis can be recycled over and over again both for your samples and those of other manufacturers.
shown in Figure 2 are from a Bio-Rad D-10[TM] analyzer.
The substitution of data was performed by cutting and pasting of chromatograms
, substituting vials, changing sample weights and changing processing methods.
The total ion chromatograms
of fresh and baked pear also showed similar flavor profiles, but some compounds were at different concentrations because they underwent a heat treatment, or there were oxidation reactions or enzyme activity in the baked pears.
In HPLC, the drugs were well separated and gave discrete peaks as shown in the representative chromatograms
of NVP (Fig.
The three chromatograms
revealed that the major metabolite produced from 25(OH)D3 was 1,25(OH)2D3.
were exposed to a phosphor screen at room temperature for 4 h, scanned, and the image digitalized using a PhosphorImager (Model 425F, Molecular Dynamic, Sunnyvale, CA) and an image acquisition and analysis program (ImageQuant 3.
showed a heterogeneous population of virus possessing either Q or K at position 136, with a dominant peak for the K136 mutant (Figure 2).
were evaluated with the BioEdit[TM] biological sequence alignment editor (http://www.
