Question
How much sample water is required in each vial to be analyzed by the QBD1200?
Summary
QBD1200 and sample volume for analysis
Answer
The amount of water sample required depends on the number of analysis replicates selected by the user.
For water samples with <4,000 ppb TOC, 8mL of water sample is consumed when analyzing each sample from the vials loaded into the autosampler. In addition, the sample line forward-flush performed at the start of each new vial analyzed uses 5 mL of the water sample in the vial. So, for example, if the autosampler was configured to analyze three samples from each vial, then analyzing each vial would consume: (3 x 8 mL) + 5 mL = 29 mL of water/vial
