Additional Information |
1) Laboratory QC duplicates are required for samples. One in ten samples should be collected in triplicate. For the sample to be triplicated, add the words “+DUP” The sample and duplicates will be submitted with the one analysis form. 2) If the chlorine residual is >5 mg/L, additional dechlorinating agent is required. For every mg/L of chlorine above the initial 5 mg/L add an additional 10 mg of Na2SO3. For example: a sample with 7 mg/L chlorine would require 70 mg of Na2SO3. Be careful not to add too much Na2SO3 to the sample because this may cause interference in the analysis. 3) If you must collect a sample for prometon, you will NOT add the acid. Make sure that the submission form is labeled well stating “PROMETON, NO ACID”. Contact the laboratory at (512) 776-7587 for currently supported analyte list. |
