ENVIRONMENTAL TESTING CATALOG SM 5310 B

DCLS Method

Total and disolved organic carbon, combustion

Reference Method

SM 5310 B

Test Description

Following the removal of inorganic carbon, organic carbon is oxidized to carbon dioxide (CO2). The CO2 is then detected by a non-dispersive infrared detector.

Sample Collection

Collect approximately 40 ml of representative sample in a glass vial sealed with TFE-backed septa preserved with H2SO4 to < = pH 2.

Storage Guidelines

Samples must be cooled to <= 4 °C after collection, and preferably shipped to the lab within 24 hours. If samples will not be analyzed within 24 hours after collection, then store samples at <=4 °C for up to 28 days following collection.
