Elemental Analysis Light, v1.08 Notes by Donna Sueper 21 Apr 2016 A few small bug fixes have been implemented. This ipf has been updated to include the Canagaratna correction in ACP 2014. This ipf is for use with stand-alone spectra, such as one may obtain via a HR PMF analysis. This ipf is self-contained and will compile by itself; it does not need the squirrel and pika infrastructure. It presumes the input spectra contains only HR ions under consideration (typically all Organic Mass, OM). Such a spectra can be generated with Pika version 1.07 or greater, because these versions have the ability to precisely define HROrg, the High resolution version of the typical AMS organic species. The ability to define HROrg greatly simplifies the elemental analysis. Much of the original APES code dealt with the cumbersome, limited assumptions about organic mass HR ions that did not have a C atom within an ion.
