Gas Chromatographic Determination of N-Alkyl Nitrosamines

Abstract

although this does not exclude the possibility of in vivo adsorption. Preliminary experiments with class-specific anti-M lg suggest that the lg on any one cell belongs to a single class. This result is most easily reconciled with the third hypothesis. The question of whether the surface lg molecules function as antigen-specific receptors remains to be answered.We thank Mr R.

Use of vacuum distillation and gas chromatography-mass spectrometry for determination of low levels of volatile nitrosamines in meat products

“…A wide range of analytical techniques was used (Fishbein and Falk, 1969) including nitrite release (Daiber and Preussmann, 1964), polarography (Heath and Jarvis, 1955;Lydersen and Nagy, 1967), tic (Preussmann et al, 1964) and glc (Serfontein and Hurter, 1966). Many of these methods are open to criticism and several recent studies (Heyns and Koch, 1970;Foreman et al, 1970;Howard et al, 1970;Henriksen, 1970) indicate that many, if not all, of these methods may lack the necessary specificity and/or sensitivity to give reliable results. It follows that if the methods themselves are suspect, the results thus obtained are also suspect.…”
