HNU PID Lamp Sensitivity

 PHOTOIONIZATION DETECTOR LAMP TECHNOLOGY


The Photoionization Detector (PID) is very sensitive and provides a response to a wide range of organic and some inorganic compounds at part per billion (ppb) levels. The HNU PID consists of an ultraviolet lamp and an ion chamber.  The detector measures the concentration of gases present in a sample  using the method of pbotoionization.Photoionization occurs when a molecule absorbs a photon (light energy) of sufficient energy, creating a positive ion and an electron as shown below:
R  + hn  = R+  + e-
The sample drawn into the ion chamber is exposed to photons generated by the ultraviolet lamp. Molecules in the sample with ionization potentials less than or equal to the energy level of the lamp are ionized. The ionization potential is that energy in electron volts (eV) needed to free an electron from a molecule. A positively biased accelerator electrode repels these ions, causing them to travel to the collecting electrode, where an analog signal proportional to the concentration of the sample is generated.  The signal is amplified to provide an analog output for graphic recording or electronic integration. Ultraviolet lamps are available in four energies; 8.3, 9.5, 10.2, 10.6 and 11.7 electron volts (eV).  Our lamps have the longest lifetime and operating hours in the industry.

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,
Jen Maclachlan, Organizer
