Abstract
Microgram amounts of organic carbon in seston and periphyton samples were measured with an infrared analyzer after combustion with an induction furnace. Replicate standards gave the same results to within 3%. Replicate seston samples prepared by filtering 135 ml of Castle Lake water or 500 ml of Lake Tahoe water usually agreed within 10%; replicated periphyton samples agreed within 20%.
