Thanks, Brian, Appreciate your help. I've been able to add the analytes of interest. Kind regards, Clint

Hi All, I've been attempting to add water quality measures such as Total Nitrogen and Total Phosphorus to GSS. As these measures are an aggregate of different constituents I cannot specify a molar mass. I have attempted to add them as a user-defined analyte and specified concentration and the units in mg/L. However, when I go to add these analytes to GSS the unit's default to mmol/l. I'm sure I've been able to add these measures in the past but have come up short. Any tips/guidance would be much appreciated. Kind regards, Clint

Hi All, It has been a few years since I last used GWB. I'm looking forward to getting started again! I've been having a few difficulties with loading up a large number of user defined anlaytes. Specifically, I want to add the following: Site ID Abs. 440 nm B (mg/L) Ca (mg/L) Mg (mg/L) Na (mg/L) K (mg/L) SO4 (mg/L) Cl (mg/L) F (mg/L) I (mg/L) FeII (mg/L) MnII (mg/L) Si (mg/L) D.O. (mg/L) d13C-DIC (‰, V-PDB) DIC (mmol/L) DNPOC (mg/L) NPOC (mg/L) TOC (mg/L) SpC (us/cm) Total Hardness (mg/L, CaCO3) d18O-H2O (‰, V-SMOW) d2H-H2O (‰, V-SMOW) DKN (mg/L) TDN (mg/L) TKN (mg/L) TN (mg/L) ORP (mV) Turbidity (NTU) Water Temp. (◦C) pH Talk (mg/L) HCO3 Alk. (mg/L) Carbonate Alk (mg/L) Br (mg/L) Cd (mg/L) Clarity B.D. (m) E. coli (CFU) Faecal Coliform (CFU) NNN (mg/L) Nitrate-N (mg/L) Nitrite-N (mg/L) TAM (mg/L) DOP (mg/L) DRP (mg/L) TDP (mg/L) TP (mg/L) SSC (mg/L) TSS (mg/L) VSS (mg/L) Zn (mg/L), Abs. 440 nm B (mg/L) Ca (mg/L) Mg (mg/L) Na (mg/L) K (mg/L) SO4 (mg/L) Cl (mg/L) F (mg/L) I (mg/L) FeII (mg/L) MnII (mg/L) Si (mg/L) D.O. (mg/L) d13C-DIC (‰, V-PDB) DIC (mmol/L) DNPOC (mg/L) NPOC (mg/L) TOC (mg/L) SpC (us/cm) Total Hardness (mg/L, CaCO3) d18O-H2O (‰, V-SMOW) d2H-H2O (‰, V-SMOW) DKN (mg/L) TDN (mg/L) TKN (mg/L) TN (mg/L) ORP (mV) Turbidity (NTU) Water Temp. (◦C) pH Talk (mg/L) HCO3 Alk. (mg/L) Carbonate Alk (mg/L) Br (mg/L) Cd (mg/L) Clarity B.D. (m) E. coli (CFU) Faecal Coliform (CFU) NNN (mg/L) Nitrate-N (mg/L) Nitrite-N (mg/L) TAM (mg/L) DOP (mg/L) DRP (mg/L) TDP (mg/L) TP (mg/L) SSC (mg/L) TSS (mg/L) VSS (mg/L) Zn (mg/L) So far I can add the normal basis species. However, when I need to specify user defined analytes, of which I have many, I'm finding that GWB is using mmol/kg as default units. I've attempted to edit these to specify mg/L but it defaults back to mmol/kg. An additional issue, and perhaps the root cause (?), is that I do not have molar mass for some of these species (e.g., Total Organic Carbon, Dissolved Non-purgeable Organic Carbon etc). Secondly, I was wondering how folk deal with adding measures of carbonate alkalinity into GSS? The lab data we use reports Total Alaklnity (mg/L as CaCO3), Bicarbonate Alkalinity and Carbonate (CO3) Alkalinity. As GWB uses alkalinity to assign major ion facies I was hoping someone had experience with adding alkalinity measures (all 3)? Any pointers on either of the above would be gratefully received. Kind regards (Cheers), Clint
