摘要：

Analytical conditions for temperature controlled pyrolysis of recent sediments were optimised using 1:10 mixtures of a Skagerrak sediment with various biopolymers. These included polysaccharides, proteins, lignins, pollen, an acylglyceride, ribonucleic acid and a marine humic acid. Lowering the S1 temperature to 180-degrees-C and increasing the S2 heating rate to 50 K min-1 was found necessary to give C(ORG) values comparable with those from other techniques. Recent sediments give complex pyrograms potentially useful in elucidation of source and bulk composition.
