The Analyzer Source

Accepted for presentation at the 2015 American Industrial Hygiene Conference and Exposition on Wednesday June 3, 2015 at SPCC: 355 C Real-Time Detection of ppb Levels of Benzene in Industrial Atmospheres  By: J.N. Driscoll and Jennifer Maclachlan Objective The OSHA method for benzene involves the collection on a charcoal tube and return to the lab, for desorption with carbon disulfide and analysis by gas chromatography with a flame ionization detector (GC-FID). While the PID is an ideal tool for detecting low or sub ppm levels of benzene, it responds to all VOC’s, so the measurement of benzene at or below 1 ppm is not very accurate.  We propose to develop a hand held GC with a PID to detect to detect low ppb of benzene in real time and “on site”. Method The hand held GC weighs less than 3 pounds, is able to operate for >6 hours on a battery,is easy to operate and has a small external tank for carrier gas (nitrogen) that can be clipped onto a belt. The hand held G

CALL FOR ABSTRACTS CLOSES 4/15/15 Scholarly journal publishing is now web based and web first, but this migration to the Internet has brought with it other changes as well. Scientists are now collaborating with each other globally in ways that would not have been possible even ten years ago. Some researchers are using social media, such as blogs and twitter, to comment on and recommend articles, and in so doing establish a reputation beyond journal article publication and citation. Some scientists are posting research results directly to the Internet, where other scientists can analyze the data and discuss its meaning. Tools and algorithms to deliver the right content to the right person help researchers navigate the ever increasing amount of scholarly content. At the same time, both scientists and funding agencies are interested in the broader impact of their research on society. A growing contingent of scientists and science communicators from academia, government, and i
