Sandwich STEM Academy Clean Energy Festival 2018

This event was funded through Massachusetts Clean Energy Center, through a grant that was written and facilitated by the Sandwich STEM Academy Science and Engineering teachers and took place at Sandwich High School for Sandwich students in Grades 6, 7 and 8 on Tuesday, May 22nd (9:30am-2pm) and showcased and celebrated renewable energies. The Clean Energy Fair’s mission is to promote sustainable and renewable energy through hands-on education. The event included a brief welcoming ceremony, an energy carnival, hands-on learning energy activities, exhibitor booths, a “passport” to record their learning experiences, and a gift bag for all students. Grade 7 and 8 students attended a brief welcoming ceremony in the auditorium, then headed to the gym, where they spent a total of 75 minutes, rotating through three stations: the energy carnival, exhibitors’ booths, and hands-on energy activities.


PID Analyzers, a Sandwich-based manufacturing company, was among the 10 exhibitors at STEM Academy…

GC/FUV for analysis of ambient (ppb level) greenhouse gases

ABSTRACT SYMPOSIUM NAME: Joint Symposium of the Separation Science Subdivisions ABSTRACT SYMPOSIUM PROGRAM AREA NAME: ANYLCONTROL ID: 2980438PRESENTATION TYPE: Oral
TITLE: GC/FUV for analysis of ambient (ppb level) greenhouse gasesAUTHORS (FIRST NAME, LAST NAME): Jennifer L. Maclachlan1, John N. Driscoll1INSTITUTIONS (ALL): 1. PID Analyzers, LLC, Centerville, MA, United States. ABSTRACT BODY: 
Abstract: 
We have recently improved the sensitivity of our far UV absorbance detector by nearly an order of magnitude so that it can now detect ppb levels of methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2). We have added a concentrator to our Portable GC 312 so that we can further improve the accuracy of the measurement. Nearly a decade ago the U.S. Environmental Protection Agency (EPA) required large emitters of heat-trapping emissions to begin collecting greenhouse gas data under a new reporting system since CH4, N2O, & , CO2 , since these gases absorb strongly in the infrared tr…

Photoionization detector with sealed or windowless discharges for ppb detection of VOC’s or and or fixed gases

ABSTRACT SYMPOSIUM NAME: Advances in Sensors & Biosensors for Environmental Monitoring

ABSTRACT SYMPOSIUM PROGRAM AREA NAME: ENVR
CONTROL ID: 2976537PRESENTATION TYPE: Oral Only

TITLE: Photoionization detector with sealed or windowless discharges for ppb detection of VOC’s or and or fixed gases

2. PID Analyzers, LLC, Sandwich, MA, United States. 

ABSTRACT BODY: Abstract: The Photoionization detector (PID) with a 10.6 eV lamp and a sealed window has been shown to be 50-80 times more sensitive for aromatic hydrocarbons than the flame ionization detector (FID) but the 10.6 PID does not respond to small molecules like formaldehyde, chloro alkanes, MeOH, C2-C4 alkanes, The 11.7 PID will respond to many of these compounds with sub ppm detection limits but it has a lithium fluoride window that results in decreased transmission after absorption o…

Analysis and identification of ppb levels of VOC’s in ambient air via GC-PID-FID

ABSTRACT SYMPOSIUM NAME: Analytical Division Poster SessionABSTRACT SYMPOSIUM PROGRAM AREA NAME: ANYLCONTROL ID: 2980432PRESENTATION TYPE: PosterTITLE: Analysis and identification of ppb levels of VOC’s in ambient air via GC-PID-FIDAUTHORS (FIRST NAME, LAST NAME): John N. Driscoll1, Jennifer L. Maclachlan1INSTITUTIONS (ALL): 1. PID Analyzers, LLC, Centerville, MA, United States. ABSTRACT BODY: 

Abstract: 
We have developed a GC system with a PID/FID in-series that will concentrate an ambient air sample so that low ppb or even ppt levels of VOCs in ambient air can be detected. We have shown that the PID (10.6 EV) has a response that increases with the number of double bonds while the FID does not have the same dependence. All these structures have the same response for the FID. This feature can be utilized to identify alkanes, alkenes and aromatic hydrocarbons in a concentrated ambient air sample. Using a capillary column, the PID /FID ratios were 15 (alkanes), 30 (alkenes) and 75 (aroma…

Talking safety: Why safety matters

Invited presentation on the PRES track at #ACSBoston
Talking safety: Why safety matters
by Jennifer Maclachlan, PID Analyzers, LLC


Safety is a core value for many professional societies including the American Chemical Society (ACS) and the American Industrial Hygiene Association (AIHA). Through education, training and leading by example, members of the ACS and AIHA can create what ACS President, Peter Dorhout, has coined an "ethos of safety". 40 young workers die each year, and 60,000 more are rushed to the emergency room due to workplace injuries. Educating students about workplace hazards that include but are not limited to chemical, electrical, physical (fall, trip, slip), emotional (includes verbal abuse, bullying etc.) and more using tools like the National Institute of Occupational Health and Safety (NIOSH) Talking Safety curriculum and abbreviated materials known as Safety Matters, developed jointly by NIOSH and AIHA, member volunteers of AIHA and ACS can introduce these…

Analysis of Greenhouse Gases in Ambient Air by GC/FUV accepted for presentation at #Pittcon

On January 1, 2010, the U.S. Environmental Protection Agency required large emitters of heat-trapping emissions to begin collecting greenhouse gas data under a new reporting system. Nitrous oxide (N2O) Carbon dioxide (CO2), methane (CH4) and are considered the main greenhouse gases in the Earth's atmosphere. These gases absorb strongly in the infrared trapping heat in the atmosphere and affecting the temperature on the Earth. These gases have been measured using expensive long path infrared analyzers or complex gas chromatography using as many as three detectors and three valves. We developed a far UV absorbance detector (FUV 1) that we will apply to analysis of all three gases. It will just require a concentrator to detect ppb levels of these gases. The FUV detector recently has been improved so that it can detect low ppm levels of these compounds. We had developed a concentrator for N2O that could also be used for CO2 and plan some additional changes to the FUV to improve its s…
