of the degradation products of Escherichia coli DH5[+ or -] at 285 and 315 nm are shown in figure 4 and 5, they were used for comparison with 1-naphthol chromatograms
data implemented in the test algorithm presented in
It appears that that peak heights in the chromatograms
of the reference standard in Fig.
As such, inspection of the HPLC chromatogram
for abnormal peaks is crucial to identify erroneous HbA1c results due to the potential presence of haemoglobin variants.
6 x 150 mm, 5 m) column and recommended mobile phase comprising acetonitrile - methanol - potassium dihydrogen phosphate (22+34+44 v/v), the desired results obtained were not according the chromatograms
provided by European Pharmacopeia (EP), but by using another column (ACE 5 C8) (4.
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.
2 *% * Values outside of expected ranges FIGURE 2: (a) Chromatogram
of HbE trait showing HbA2 24.
Therefore, the HPLC chromatogram
for the polyphenols of the extract with excipient in the capsule was different from that of the extract alone, without excipient.
Isoniazid, pyrazinamide and ethanbutol, which are often co-administered with RIF, did not interfere with the chromatograms
In fact, this is only a segment of the entire Macondo oil chromatogram
The HPLC chromatogram
identified 3 major hemoglobins, HbA, HbS and a large amount (15.
Now, if you think the FDA has been sleeping on the job, there is a little snippet from the Administration's Web site (19) that is available for all to see: "The printed paper copy of the chromatogram
would not be considered a "true copy" of the entire electronic raw data used to create that chromatogram
, as required by 21 CFR 211.
