Annotations
Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.
Photodiode-array spectral homogeneity across the main peak would convert 99.93 % from a good number into a checked one. It is a free measurement on any instrument that already has the detector.
Photodiode-array spectral homogeneity across the main peak would convert 99.40 % from a good number into a checked one. It is a free measurement on any instrument that already has the detector.
Peak purity by spectral comparison across the main peak flags co-elution where chromatography cannot resolve it. It does not quantify the co-eluting species, but it establishes that one exists.
Photodiode-array spectral homogeneity across the main peak would convert 99.33 % from a good number into a checked one. It is a free measurement on any instrument that already has the detector.
Photodiode-array spectral homogeneity across the main peak would convert 99.72 % from a good number into a checked one. It is a free measurement on any instrument that already has the detector.
Photodiode-array spectral homogeneity across the main peak would convert 99.51 % from a good number into a checked one. It is a free measurement on any instrument that already has the detector.
