We used proton-transfer-reaction mass spectrometry (PTR− MS) to examine the products
formed when ozone reacted with the materials in a simulated aircraft cabin, including a …

Rennet whey and skim milk were compared as media for fermentation by commercial
cheese, yogurt, and probiotic starter cultures. Effect of culture, medium, and their interaction …

A major new discovery made in the last decade is that plants commonly emit large amounts
and varieties of volatiles after damage inflicted by herbivores, and not merely from the site of …

We present a newly developed instrument that uses proton-transfer ion trap-mass
spectrometry (PIT-MS) for on-line trace gas analysis of volatile organic compounds (VOCs) …

Grass crop species, rice and sorghum, that are widely grown in the southeastern Texas
region were analyzed for release of biogenic volatile organic compounds (VOCs) in …

We have used a newly developed proton-transfer ion-trap mass spectrometry (PIT-MS)
instrument for online trace gas analysis of volatile organic compounds (VOCs) during the …
