I’d like to know how ESdat would calculate Xylenes in a situation where Xylenes (o) and Xylenes (m & p) have been analysed using two different methods, resulting in two results for each analyte. 

Would ESdat combine all four results or would it select two and if so, how would it select the two?

If an analyte is present twice the following logic is used to determine which value is used:

Both Detects - Maximum Value

Both Non Detects - Minimum Value 

One detect and one non-detect - Maximum Value 

Non-detect multipliers are treated the same as elsewhere in calculating combined compounds.
