If I use the silica Series 5500 analyser molybdate 3 reagent, how do I account for the reagent blank?
Summary
Reagent blank using Series 5500 molybdate reagent
Answer
The ULR Silica program 645 (method 8282) allows for a reagent blank value to be entered into the spectrophotometer. The reagent blank is based on the reagent part number. See below for reagent blank options (as provided in the “before starting the test” section of the procedure). *Verify the accuracy of the ULR method using a 500ug/L standard solution.

Series 5000 2.9L 199503 = multiply reagent blank on label by 1.09
molybdate 3 100mL 199532 = use the blank value on the bottle
molybdate 3 Reagent 1L 199553 = use the blank value on the bottle
