METHODS FOR THE DETERMINATION OF NITROGEN AND CARBON IN SMALL AMOUNTS OF PLANKTON

THEODOR v. BRAND 1

1 From the Laboratory of Zoöphysiology, Copenhagen University

The method of Krogh and Keys for nitrogen determination is adapted for determinations on plankton. The range of nitrogen to be determined is 0.5-5ggr, the accuracy about 10 per cent.

A method for the determination of small amounts of carbon for the same purpose is described. Amounts of 10 to 100ggr C can be determined with an accuracy of about ± 3ggr C.
