One vial is marked as a “blank,” and three or four vials are marked with known standard levels. Two vials are then marked for the wastewater sample to make a duplicate run. Note: If multiple wastewater samples are being run, at least 10% of samples are duplicated. 5. 2 mL of liquid are added to each vial. In the case of the “blank,”

Method 524.4: Measurement of Purgeable Organic - EPA

INTERFERENCES 4.1 SAMPLE CONTAINERS, SHIPPING AND STORAGE - Volatile organic compounds (VOCs) present in ambient air, shipping containers and in the laboratory environment may permeate the PTFE-lined septa of the sample vials or be present at high concentrations in the headspace of the vial (especially if the vials were prepared in a laboratory).

Total Organic Carbon (TOC) - Water Quality Parameter Overview

Total organic carbon is a measure of the amount of organic compounds contained in a water sample. Organic carbon-containing compounds can either be dissolved in water or exist in water as undissolved, suspended material, or liquid. This organic matter can enter water naturally and through man-made sources/processes.

EPA Method 524.2: Measurement of Purgeable Organic Compounds

INTERNAL STANDARD (IS) -- A pure analyte(s) added to a sample, extract, or standard solution in known amount(s) and used to measure the relative responses of other method analytes and surrogates that are components of the same sample or solution. The internal standard must be an analyte that is not a sample component. 3.2
