LimeR protocols and calculators
Jinsheng Huang and Paul Fisher (University of Florida), with contributions from William Argo (Blackmore Co.), and Paul Nelson (North Carolina State University).
The pdf file contains detailed laboratory procedures for the LimeR protocols and provides instructions to use the Excel files. Materials for conducting LimeR series tests are also provided.
Overall LimeR Model Oct 2012.xlsx
This Excel file combines the LimeR protocols and their underlying research and chemistry into a prototype Excel spreadsheet model called 'Overall LimeR Model'. Please refer to pages 32-37 in the 'LimeR Protocols.pdf' for details.
LimeR tests 1h.xls
This Excel file can be used for both LimeR Substrate Lime Requirement Test and LimeR Lime Reactivity Test. This Excel file contains 'Lime reactivity test' worksheet and 'Substrate lime requirement test' worksheet. For details, please refer to page 13 and page 17 in the 'LimeR Protocols.pdf'.
Residual Lime Calculator.xls
This Excel is to be used for the 'LimeR Residual Lime Calculator'. The Excel file contains 'System Calibration', 'Standard Curve' and 'Residual Lime Calculator' worksheets. Please refer to page 21 in the 'LimeR Protocols.pdf' for details.
