Hi Tom,
I have been questioned on the relationship between calculated TDS and Density outputs in SpecE8 and was wondering if you might be able to provide some insight.
Two water compositions, with very different TDS (confirmed by field EC measurements) had very similar density.
SpecE8_output_SE_run4: TDS 1.0 mg/L Density 1.018 g/cm3 T = 18 deg C
SpecE8_output_SE_run16: TDS 34561 mg/L Density 1.017 g/cm3 T = 18.5 deg C
I noticed that an automatic density calculation is based on chlorinity and temperature. For both of these anaylses, Chlorinity is 0.00 molal. I can't see where or how chlorinity is caluclated or input.
Could you please give me a few ideas?
Cheers
