H/Comet-Mobile by Haverly Systems allows H/Comet customers to access their existing H/Comet assay libraries, slates, blends, and cut sets on the go by logging in with their H/Comet credentials. Users have several search filters they may use to find the perfect assay and view detailed assay data. Assays can be re-cut with H/CAMS technology by editing the gray boiling point fields, or with a saved cut set. Users can also create and modify cut sets (with or without tray inefficiencies). In addition, users can access and modify existing slates or create new ones. Slate operations such as cut comparisons and group graphing can be done on a slate. H/Comet Mobile also supports blends, so users can access (and modify) existing blends as well as create new ones. Finally, assays can be graphed and then analyzed with value/cut lookup tools.
