It's STEM Journey time of year and we've partnered with Penn State Berks Chemical Society, A Student Chapter of the American Chemical Society to bring our STEM Journey and Cape Cod Science Cafe audiences an amazing opportunity to participate in this virtual and FREE after school enrichment series that encompasses all that STEM Journey offers but weekly and over the course of 3 months.
STEM Journey and the Cape Cod Science Cafe are partnering with this
FREE VIRTUAL AFTER SCHOOL CHEMISTRY PROGRAM organized by The Lehigh Valley Section of the American Chemical Society (LVACS) funded by the American Chemical Society (ACS) Diversity, Inclusion, & Respect Grant, is partnering with community organizations to provide an interactive, virtual after-school chemistry enrichment program via Zoom! 

This program provides students with an opportunity to make new friends while meeting and connecting with scientists and college STEM students from across our vibrant, diverse communities. Not only will students learn about chemistry careers, and summer research opportunities for high schoolers through the ACS Project SEED Program, but weekly activities also include free fun experiments, themed demonstrations, guest speakers, a movie watch party, book club, and more! 

Please do let me know if you decide to signup for this program (Penn State Berks is handling registration).

Thanks and hope to see you Wednesdays at After School Chemistry!

All the best,

  • A New Simpler Method for Mercury in Water using HG/PID
    • Session Number: L55-02
    •  
    • Friday, March 12, 1:50 PM - 2:10 PM

    Description

    At the 2015 PITTCON held in New Orleans, LA we discussed "A new method for the analysis of ppb levels of mercury in air and water". This method used hydride generation (HG) to generate elemental mercury which was made specific using gas chromatography (GC) to remove any organic interferences configured with a photoionization detector (PID). In 2021, we have developed a new simpler method of hydride generation by adding permanganate to the reducing solution to oxidize any organic compounds, we remove any residual water, then employ a PID with a 10.6 electron volt (eV) lamp to detect mercury which has an ionization potential of 10.4eV. Eliminating the need for the use of a GC with this new method not only saves time, it is more cost effective. Additionally, the detection limits for the HG/PID have been improved by at least an order of magnitude.

  • Optimization of a GC/PID Method for Terpene Identification and Analysis
    • Session Number: L53-06
    •  
    • Friday, March 12, 3:25 PM - 3:45 PM





    Description

    At PITTCON 2020 in Chicago, IL we discussed "Analysis of Medical Cannabis Terpenes by GC-PID" and have spent a significant amount of lab time optimizing the gas chromatography (GC) by photoionization detector (PID) method.This optimized method includes improved chromatography (improved low dead volume PID, peak resolution and comparative analysis of carrier gases), the addition of proportional valves for the management of flow control and makeup gas, evaluation of methods for sample handling: Headspace, dilution, and, direct injection, and the development of a terpene profile library.
