Hello,

You are probably importing using the "Crosstab" or "Tabular" method that is easiest for historical data.

This comes from the "Importing Historical Chemistry" section of the help file as applies to importing cross-tabbed data: 

 If a result is Field Filtered the word "Filtered", "Dissolved" or "Soluble" (case insensitve) needs to be included in the compound name. If this is the case the results will automatically be given a "Total_or_Filtered" value of "F". Result prefixes can be included with the result.

I hope this helps,

Alex

Hello,

Please have a read of http://www.ESdat.net/ESd...istorical_chemistry.htm, and if that doesn't resolve it, check if the data is actually already in the database.

You may like to Check Units in ESdat (to make sure there are no unit conversion issues), then produce a Chemistry Output table, to confirm what has already been imported.

Regards,

Warwick
