Some parameters affecting the accuracy of various approaches to methylmercury (MeHg) determination in biological and environmental samples were studied. Different isolation techniques (ionexchange, extraction, volatilization, distillation) and final measurement via coid vapour atomic absorption spec
The determination of methylmercury in sediment by gas chromatography with electron capture detector is proposed. Performance of a 0.53 mm i.d. capillary column SPB-608 has been evaluated. A procedure of extraction of methylmercury from sediment, based on an alkaline digestion (KOH/CH 3 OH) in ultras
## Abstract The preparation of (glass) capillary columns of high quality is still not without difficulties. Six problems in this context are highlighted. Column material choice(l), glass wall modification(2) and coating(3) are considered to have reached a satisfactory level. Deactivation(4) is stil
