Lineage | Samples are collected from a boat by surface water collection in sterilised glass nalgene bottles. Samples are filtered within 24 hours under vacuum filtration, using Whatman GF/C47mm glass microfibre filter papers. Filter papers are left overnight at 4 degrees celcius in the dark with cold acetone to extract. Analysis is performed in house on a Turner Designs 'Trilogy' fluorometer. Samples are analysed in duplicate and the average is reported. Solid standard QCs are used at the start and end of runs and reported on Shewart charts. Calibration is carried out at 4 points using RS AQUA liquid standards. Participation in QUASIMEME is mandatory for all staff who take part in the analysis. In house training is provided by competent staff members. Analysis is of Chlorophyll a only. |
