HPLC-DAD-ESIMS Identification of Light Harvesting and Light Screening Pigments in the Lake Sediments at Edmonson Point

الملخص EN

The composition of sedimentary pigments in the Antarctic lake at Edmonson Point has been investigated and compared with the aim to provide a useful analytical method for pigments separation and identification, providing reference data for future assessment of possible changes in environmental conditions.

Reversed phase high performance liquid chromatography (HPLC) with electrospray-mass spectrometry (ESI-MS) detection and diode array detection (DAD) has been used to identify light screening and light harvesting pigments.

The results are discussed in terms of local environmental conditions.
