A Multifunctional Analyzer for IAQ Monitoring #IAQ, #ATF, #photoionization,#PID,# VOC's, #Indonesian _National_Police,#CO2, #Model_102

This paper describes a Model 102+ for monitoring VOC's (ppb), CO2 and other contaminants (using electrochemical sensors) for monitoring the condition of indoor air quality. A headspace method for soil & water is also described along with information of the monitoring of accelerants in arson investigations by ATF and the Indonesian National Police.

A photo of the Model 102 with 9.5. 10.6 & 11.7 eV Snap On Heads is shown in the photo below:

Relative Photoionization Sensitivities for the HNU and PID Analyzers PID's #AIHA, #industrial hygiene, # photoionization, #response factors

A list of the relative photoionization sensitivities and ionization potentials for more than 500 compounds are listed below for the HNU and PID Analyzers Models PI101, HW101, IS101, DL101, & DL102:

Photo Ionization Relative Sensitivities and IP's for HNU and PID Analyzers Instruments

Note that in the 102 & 102+ the sensitivities are embedded in a library containing 300+ response factors for the 10.6, 9.5 and 11.7 eV lamps. Any of these gases in the table can be used for calibration and the response factors will still be valid. A photo of the PID Analyzers Model 102 with Snap on Heads is shown below.

Suffolk University Solar Energy Project #Suffolk

Suffolk Unversity has a field station in Maine. In addition to the biological studies there, the Physics Department, under the direction of Prof. Walter Johnson, has a research project comparing wind and solar generated power. A preliminary paper was given at the Second Cape Cod Science Cafe in Hyannis, MA in April 2011. The Third Cape Cod Science Cafe on the Topic of Recycling is coming up shortly. Look for the announcement.
