The Agilent rep was in the position to prioritize our provider request and be onsite six times earlier compared to the quoted support date.
Separation aspect (alpha) is a relative comparison on how effectively two neighboring components from the mixture were separated (i.e., two neighboring bands over a chromatogram). This component is defined regarding a ratio on the retention elements of the set of neighboring chromatogram peaks, and may additionally be corrected for from the void volume from the column.
