PID Analyzers' Technical Program SUNDAY at Pittcon 2020





  • SUNDAY AFTERNOON AT PITTCON 2020:

    Analysis of Medical Cannabis Terpenes by GC-PID   

    • Room: Room W176A
    • Session Number: 5-3-3
    Sunday, March 01, 2020: 2:10 PM - 2:30 PM
    Authors: Driscoll, Maclachlan (presenting)

    Description

    With recent changes and liberalization in the law, cannabis is now a rapidly growing industry and lab testing is required for medicinal and recreational cannabis as well as residual cannabis solvents. There are a few gas chromatography (GC) detectors presently used for this analysis but each has its challenges. The Flame ionization detector (FID) requires hydrogen support gas and can have problems with flameout during injections. The GC Mass Spectrometer (GCMS) detector is not very useful for analysis of residual solvents or terpenes since more than a dozen of the important terpenes have an m/e of 136 with different secondary ions. Alpha and beta-pinene have similar parent ions but slightly different secondary ions. The Photoionization Detector (PID) does not require any support gases like hydrogen, has a strong response for terpenes, has a long lifetime lamp, is non-destructive and can be easily added to any GC. It has both analog and digital signal outputs and will accept a digital signal from the GC to autozero the amplifier at the start of the run. One interesting detector combination is using a PID (non-destructive) coupled with an FID in-series for structural identification of peaks (1). We used a new to the market GC model 323 with a PID and have developed a method for profiling of medical cannabis terpenes (22 components). We use a low mass capillary (624) column and a PID for the analysis. We can cool the low mass oven from 290 degrees C to 60 degrees C in less than 2 minutes thereby reducing the overall analysis time. This system can also be used for residual solvent analysis that involves the extraction of active ingredients from cannabis using solvents such as ethanol, carbon dioxide, butane, and water. 1.

    ACS SUNDAY EVENING POSTERS:

    Rapid Analysis of Volatile and Semivolatile Organic Compounds with a Field Portable GC-PID
    Authors: Driscoll, Maclachlan (presenting)

    Room: Skyline Ballroom


  • Session Number: 6-2-11P

Sunday, March 01, 2020: 5:30 PM - 7:30 PM

Description

We used our line operated Portable Gas Chromatograph (GC-311- 115VAC) with a Photoionization Detector (PID) for many years at hazardous waste sites and for industrial hygiene surveys of volatile hydrocarbons at ppm and ppb levels. In order to bring our Model GC312 directly to the field, we needed a longer battery life. We have developed a low mass capillary column which required significantly less power, improved the insulation, and used a lower power PC and a lower power color monitor. Now we can operate the GC for 4-6 hours at 75 degrees C or for 8-10 hours at 5-10 degrees C above the ambient temperature. This allows us to analyze volatile compounds like vinyl chloride monomer (gas), benzene (BP 78 degrees C) at 30-40 degrees C or non volatile compounds like 1 vinyl 2 pyrrolidone (BP 148 degrees C), ethylbutyric acid (BP 195 degrees C) and, Napthalene (BP 218 degrees C) or other PAH’s at 75 degrees C to detect ppm to ppb levels. We can operate the GC at temperatures up to 150 degrees C but above 75 degrees C, the GC has to be line powered. Benzene at refinery or chemical plant fence lines can be detected at low ppb levels with an analysis time of < 30 seconds. A complete BTEX analysis (benzene through o-xylene) can be accomplished in 3 minutes.

CAPE COD CELEBRATES THE INTERNATIONAL YEAR OF THE PERIODIC TABLE AT SCIENCE SUNDAY FUNDAY



The Cape Cod Science Cafe and the Sandwich Public Library present Science Sunday Funday in celebration of The International Year of the Periodic Table on Sunday, December 15, 2019, from 1pm-3pm. This is a FREE event for everyone. Students in grades K-8 will enjoy and learn about the importance of the Periodic Table through hands-on activities while older students and adults will learn from the lecture by the American Chemical Society's
Dr. Jens Breffke

International Activities Committee Chair, Dr. Jens Breffke, as he discusses the history of the Periodic Table, the interdisciplinary use of the Periodic Table of the Elements in the sciences and how scientists around the world have celebrated this 150-year-old discovery by Dmitry Mendeleev during 2019, the International Year of the Periodic Table. There will be two seatings for the lecture portion of the event: 1pm and 2pm. You must RSVP using the Eventbrite to reserve a spot for either of the identical lectures as seating at this event is limited. 

This is the second time the Sandwich Public Library has hosted the award-winning Cape Cod Science Cafe for families. The first time was in 2011 during the International Year of
Chemistry which featured hands-on activities related to healthy kids. This time around we are adding the Periodic Table Talk lecture for older learners so we can offer something for every science enthusiast. Hands-on Periodic Table themed activities will be led by three local sections of the American Chemical Society: The Northeastern Local Section (of which Cape Cod is part of), the Lehigh Valley (Pennsylvania) and the Rhode Island Local Section. PID Analyzers, LLC, Palladium Science Academy, Scientists are Superheros, too, Cape Cod Learning Tours, Smithers Viscient, LLC. PiRShared, and Marine Educators, Eben Franks will be leading hands-on activities related to the Periodic Table of the Elements.




The Cape Cod Science Cafe is a cooperative effort between Sandwich-based business, PID Analyzers, LLC and the Northeastern Section of the American Chemical Society to create a social and educational forum where scientists and the general public, including students, can meet in a relaxed atmosphere and fuel their passion for science and STEM-related fields.

What to expect If you plan to attend the event: Please RSVP if you want to attend the lecture as seating is very limited. Use this link to reserve your tickets: http://bit.ly/ScienceSundayFundaySPL There are 1pm and 2pm lecture seatings available. Tell your friends and family to come on down to the Sandwich Public Library for free hands-on science activities that will run continuously from 1pm-3pm. We hope you can join us at Science Sunday Funday at the Sandwich Public Library.

And ACTION: AIHA announces their Young Worker Health & Safety Policymaker Meeting Request Campaign

Every minute, a young worker is injured on the job, and every day, a young worker loses their life as a result of an incident at work. By working with policymakers we can help protect young workers. One of the first steps on the road to protecting workers is meeting with policymakers, which is also one of the most effective forms of advocacy.



The American Industrial Hygiene Association (AIHA) has launched an action alert titled Young Worker Health and Safety Policymaker Meeting Request with a pre-written letter to your LOCAL policymakers. All you have to do in click on the link below, fill in your name and address and click on START WRITING, which opens up a letter to your policymakers (you can select the letter as is or customize it if you wish), then click SEND.

The letter requests a meeting. The AIHA Teen Workplace Health and Safety Task Force can assist you with the next steps in this advocacy process by providing preparatory materials for your meeting/visit. Contact us to learn more. If meeting with legislators is out of your comfort zone, please send the action alert anyway and pass on the lead to the AIHA Teen Workplace Health and Safety Task Force and we'll follow through with it either by identifying someone local who is willing to take the meeting or scheduling a telecon if we need to complete the meeting remotely. 

Advocate for the education of young workers so that they are able to identify and correct workplace hazards and teach them to expect a safe and healthy workplace. Take action now.
