Science on the Street on the Cape or how my six year old and I bonded

I spent Saturday afternoon at the Cape Cod Museum of Natural History participating in the Cambridge Science Festival, Science on the Street STEM outreach event. This was an event I had planned to attend with my family but instead we ended up as exhibitors, representing the American Chemical Society. My eight year old daughter enjoys the VIP experience of working at a science festivals for several reasons: getting there before the public is allowed to enter, as the kid of a volunteer she gets to check out and try all the cool activities before everyone else since the other exhibitors are eager to practice on a real kid before the rush and the best is of course having a place to come and rest between doing fun activities. 

Since both of my girls had planned to assist me at the ACS table, I told each of their teachers about it. The second grade teacher suggested I make a flyer that she would send home with the students in the class plugging the event with a call-out box stating that their…

Sensitive photoionization (PID) method for the measurement of ppb levels of inorganic arsenic in well water

This research paper is part of the Arsenic Contamination in Food and Water symposium Agricultural & Food Chemistry Poster Session which precedes the two day oral symposium at #ACSNOLA.    


166 - Sensitive photoionization (PID) method for the measurement of ppb
 levels of inorganic arsenic in well water

Bennington College is located in southwestern Vermont, an area that has recorded many
 bedrock wells with arsenic levels near and above the 10 ppb limit. We are interested in 
exploring the geochemical conditions and redox chemistry that contributes to the 
solubilization of As(III), the more toxic form of arsenic. We plan to set up some model 
systems in the lab as well as test conditions with samples of local bedrock. We would have 
chosen the older colorimetric method rather than the AA or ICP-MS bec…

Comparison of sensitive methods for the measurement of inorganic arsenic in apple juice: Photoionization (PID) and ICP-MS

This will be presented in the Analytical Methods subsection of the two day Arsenic Contamination in Food and Water Symposium at the American Chemical Society Spring National Meeting in New Orleans April 10 and April 11, 2013 on the AGFD Track.  299 - Comparison of sensitive methods for the measurement of inorganic arsenic in apple juice: Photoionization (PID) and ICP-MS

Authors: Jack Driscoll1,  Jennifer Maclachlan1,  (1) PID Analyzers, LLC, Sandwich, MA 02563, United States

In January of 2012, Consumer Reports found 10% of apple juice samples tested from five brands had total arsenic levels above the drinking water standard of 10 parts per billion. Most of that arsenic was inorganic arsenic, a known carcinogen. American apple juice is made from apple concentrate, a majority of which is imported from China. Inorganic Arsenic has been detected as AsH3following reduction via AA or ICP MS. The cost of these types of spectrometers is in the $60-200K price range. Many labs would have to choos…

PID Analyzers at #Arablab 2013

Together with our friends at Hillsborough Scientific we will be exhibiting at Arablab 2013 in Dubai 10th-13th March. 

The PID Analyzer products that will be displayed at Arablab Stand No: 816/916 are: Model 102+ portable hydrocarbon analyzer, customize with up to 3 additional sensors, Model 210 paramagnetic oxygen analyzerand Model114 IR-based analyzer for leak detection, environmental, area, or laboratory monitoring applications.

Here is a recent presentation that we did on our Model 102+, one of the featured portable analyzers which will be on display at Arablab and at the Quadrex Corp booth #1202 at Pittcon 2013 in Philly.

Objective:

There is a need to know the exact composition of the air that workers will be breathing in confined space areas like coal mines. The conventional four gas analyzer does not have the accuracy, range or a sufficient number of sensors to assess extremely toxic atmospheres. Method Confined space atmospheres are typically measured using four gas meters for LEL, O2, CO, H2S. Confined spaces where unknown gases (other inert or toxic gases) may be present include tunnels, manholes, utility vaults, pumping stations, storage tanks, coal mines etc. 

While it is okay to know that an atmosphere is possibly deficient in O2, it is also im…
