Anatel Operator Manual
Use extreme care when installing and removing the sample vessel and vials. Contact with the
exposed needle could cause serious injury.
13) Press Enter to view the average of the blank replicates, which establishes the
reference for the calibration, then press it again to continue.
14) Remove the blank bottle and insert the requested standard (250, 500 or 750 ppb).
Press Enter and its contents are sampled, analyzed and reported.
15) Repeat step 14 for each of the selected standard levels. The blank average is
subtracted from each replicate and the results for each are displayed once all analyses
have been completed. Note that only one blank is analyzed, not one blank per
calibration level.
16) Press Enter to display the correlation coefficient. The instrument is suitable for
measuring TOC in HPW if the slope change is within ±15% of the factory calibration.
