From: Acetaldehyde and hexanaldehyde from cultured white cells
Chromatogram of hexanaldehyde from the bioreactor headspace of HL60 cells from 4-, 24- and 48-h incubations and ambient lab air. For clarity, media chromatograms are not shown (see Fig 4 for associated media responses and standard deviations). Hexanaldehyde was not present in appreciable concentrations in any of the identified sources of contamination such as Teflon vials, plastic culture ware, room air samples, and incubator air samples.
