Direct mass spectrometry combined with automation has potential to significantly increase sample throughputs in routine laboratory analysis. This article describes the performance of direct-analysis selected ion flow tube mass spectrometry (SIFT-MS) integrated with automated thermal desorption. The performance of thermal desorption-SIFT-MS in several air quality applications of conventional thermal desorption-gas chromatography mass spectrometry is described. Compared to gas chromatography mass spectrometry analysis, one of the most significant advantages of thermal desorption tube analysis using SIFT-MS is that volatiles are analysed as they are desorbed, providing at least four-fold greater throughputs.  ....

“So, what happens with your Biosafety Level 3 lab waste?” I asked the laboratory manager. “Our safety assessment says to just mix it with sterilant wash it down the drain - there is worse stuff down there already.” “How about genetically modified material?” “Yeah, that goes the same way - It’ll die in the drains”.
Treating biologically hazardous waste in such a way is not uncommon in the UK - the combination of chemical sterilants and a well-developed system of sewerage and treatment plants can handle a wide range of biologically active substances, but it is not a failsafe system. ....

Saving the Planet, One Meal at a Time


Saving the Planet, One Meal at a Time
Numbered footnotes, with hyperlinks, appear at the end of this article.
My attitude toward becoming a vegan was similar to Augustine’s attitude toward becoming celibate “God grant me abstinence, but not yet.” But with animal agriculture as the leading cause of species extinction, water pollution, ocean dead zones and habitat destruction
2, and with the death spiral of the ecosystem ever more pronounced, becoming vegan is the most important and direct change we can immediately make to save the planet and its species. It is one that my wife who was the engine behind our family’s shift and I have made. ....
