The Analyzer Source

Accepted for presentation at #ACSDenver 2015 on March 23, 2015: PAPER ID : 2152487  PAPER TITLE: “Separation of mercury from VOC’s and selective detection using gold film amalgamation and photoionization detection”  DIVISION: [ANYL] Division of Analytical Chemistry SYMPOSIUM : Advances in Analytical Separations  PRESENTATION FORMAT : Oral  Authors: J.N. Driscoll and J.L.Maclachlan, PID Analyzers, LLC Sandwich, MA USA We used a sensitive but nonspecific photoionization detector (PID) with a 10.6 eV lamp to measure mercury that has an ionization potential of 10.43 eV. The PID responds to both mercury and VOC’s and the VOC’s have to be removed to make the technique specific for mercury. The chemistry of the gold/mercury amalgam makes this method specific for mercury and eliminates interference from VOC’s. This technique also concentrates the sample making the method sensitive to sub ppb levels. Mercury permeation tubes were used to generate levels from 0.02 to 1

It was a perfect New England October Saturday for the Cape & Islands Boy Scouts Council of America to have their mostly outdoor Wicked Cool Autumn Welcome at BSA Camp Greenough in Yarmouthport, MA.  This is the second  consecutive year that we have partnered with the Cape & Island Council of the Boy Scouts of America for their Wicked Cool Autumn Welcome which features a fall themed day of family fun: pumpkin carving, wood-working, fishing, archery and more . Last year and this year the and more was a science cafe in celebration of National Chemistry Week! We won a ChemLuminary Award from the American Chemical Society for our 2013 collaborative efforts. Above is the participation patch that was given to all 400 children in attendance.  This is what the cafe part of a science cafe for kids looks like: cookies, hot chocolate and oranges. Since it was almost Halloween, we had Halloween themed cookies. Special thanks to Amy Zahn and her son for baking 30 dozen cookies

Accepted for presentation at Pittcon 2015 New Orleans, Louisiana March 8-12 2015 Abstract Number: 1370 - 5 Session 1370 - Advances in Energy Research: From Unconventional Fuels to Solar Energy Day and Time:  Tuesday, March 10, 2015, 03:05 PM Room 240 Authors: Jack Driscoll and Jennifer Maclachlan , PID Analyzers, LLC Significant shale deposits exist in 22 states including the Northeast states of Ohio, Pennsylvania, and New York Utah and Wyoming in the West; and gas-producing states such as Texas, Louisiana, Arkansas and Mississippi. The use of horizontal drilling and hydraulic fracking of shale has catapulted the US into the leading producer of natural gas in 2013.  Natural gas is bought or sold based on the quantity of energy delivered. The product of the concentration (determined by gas chromatography) and the heating value (BTU) determines the BTU content of the fuel. Although the natural gas from Marcelis shale is primarily methane, the compositi
