Abstract
The method of Krogh and Keys for nitrogen determination is adapted for determinations on plankton. The range of nitrogen to be determined is 0.5-5γ, 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 100γ C can be determined with an accuracy of about ± 3γ C.Keywords
