Sum of Results, Dynamic vs Others Which RPF is Right?
Horicon Co-Location Study • Horicon is AMNet WI-07, since 2011 • Extra instrumentation provided by AMNet, multiple audits by Mark Olson throughout study • Study intended to investigate RPF effects • Two instruments between 09/2013 and 09/2014 • Three instruments between 09/2014 and 01/2015
Horicon Co-Location Study Initial Phase (09/2013 – 04/2014) • Compare Typical RPFs to establish variability • Confirm Dynamic RPF • Swap between instruments to confirm readings related to RPF, not other instrumental effect • Frequent inlet flow measurements
Horicon Co-Location Study Second Phase (04/2014 – 08/2014) • Typical RPFs only in primary system (reported to AMNet) • Clean High Reading RPF in stages (stem only, remove quartz wool, acid/water/methanol wash) • Repeated for 2 High Reading RPFs
Horicon Co-Location Study Final Phase (09/2014 – 01/2015) • Typical RPFs only in primary system • Confirm effectiveness of cleaning • Evaluate additional RPFs • Clean Low Reading RPF, Not completed prior to end of study
Horicon Co-Location Study • Overall, 9 RPFs Used: 1 “Dynamic”, 1 BECAME “Dynamic”, 6 “Typical”, 1 consistent Low Reader • While cleaning did appear to convert “Dynamic” RPFs to “Typical” status, they quickly returned to “Dynamic” status. Does this imply more frequent cleaning required, or is it an artifact from the cleaning being completed in summer? • Note in final slide how sometimes all 3 RPFs line up, but at other times both “Dynamic” pieces responding much more strongly. Does this indicate preferential capture of different PBM forms?
Glassware Effects on PBM Measurements Which RPFs are more accurate? What are we measuring? Where do we go from here??
