Abstract: Analysis methods are provided that include generating a sample data set using a sample, the sample data set comprising first and second data sets, wherein each of the first and second data sets comprises at least one of an analytical parameter and a sample characteristic acquired using the analytical parameter; and using the first and the second data sets, identifying the sample. Instruments including an ionization source configured to apply different ionization energies to a sample to provide different sample characteristics, and processing circuitry configured to process the different sample characteristics to identify the sample are provided.

Abstract: A pneumatic raisin harvester for harvesting dried-on-the-vine raisins grown on a trellis system comprising a plurality of support stakes and a trellis wire interconnecting the stakes spaced apart from the vine trunk. The harvester has a support assembly attached to and transported by a tractor or other vehicle. A support arm extends outwardly from the tractor to support a harvesting head having a head enclosure configured to straddle the trellis wire and support stakes. A crop separating mechanism, such as a plurality of beater rods, disposed inside the head enclosure dislodges raisins from the vines. A raisin collecting system transports the raisins to a venturi inlet that is hydraulically connected to a hydraulically powered pneumatic conveying system comprising a blower that discharges pressurized air through one or more air tubes so as to deposit the raisins in one or more raisin bins on a bin trailer towed by the tractor.
