Filter solution through a 0.45-micron syringe filter. Sample Preparation: Accurately weigh an amount of sample into a volumetric flask and dilute to volume with 0.1 N HCl. If necessary, dilute the sample so the final concentration approximates the standard concentration or falls within the linear range. Filter solution through a 0.45-micron filter.
Sample Preparation - Filter papers for EPA Method 353.2. We've experienced some trouble while running nitrate (NO3) by automated colorimetry using EPA Method 353.2. There seemed to be an interference from the filter paper that results in a false positive. We've noticed that the false positive was not seen when analyzing for NO2.
