The zip folder contains Chemtax.exe, Chemtax2.dll, Testrun195.xls, PicoDataWorkup.xls (example), CHEMTAXHelper for V195.xlm.
Also included are two Word files (Chemtax 195 Instructions.doc, and Chaxmanw.rtf, which is the manual for Version 1).The latter manual contains details on the algorithms used in Chemtax, which are unchanged, but the operating instructions in that manual are superseded by those in Chemtax 195 Instructions.doc.
