They have patented an interface for APCI-MS that uses a venturi pump to sample air from the nose, mouth or headspace above a food. |
With travelling reduced to a manageable level, stress levels have decreased, and headspace has been restored. |
Transfer the apple sauce to clean pint jars, leaving one-half inch headspace. |
The larger sample size was used if the level of malodor observed in the headspace of the sample was low. |
Odors were collected from the headspace of individual flowers and analyzed by gas chromatography coupled to mass spectrometry. |
A dummy bolt is in place in the receiver so headspace is set at the same time. |
