| Extraction methods for POPs Pesticides | The extraction in water is made with cartridges of C18, later solution with suitable solvents and concentration under nitrogen atmosphere.
Determination in GC-µECD.
The extraction in soils and sediments is done with irradiation of microwaves on the matrix previously dried with anhydrous sodium sulphate, using a mixture of suitable solvents. 8321u03pfd|1010D1E6ADDITIONALS|COMMENT 8321u03pfdidval|120 8321u03pf8|0010D1E61973|UNEP_Labs|ADDITIONALS|COMMENT|10C6C791-1C7A-4A06-A24D-BBFC64F74236 |
| Quality Control and Costs | The applied quality controls are: analysis of samples by duplicate, recovering of fortified samples and comparative analysis with standards. Control of chromatographic bullfight with control standards. Control and preventive maintenance of the used equipment. Since the laboratory is in a stage of development of analytical methodology, still the costs of the different analyses by sample have not been defined. 8321u03pfd|1010D1E6ADDITIONALS|COMMENT 8321u03pfdidval|121 8321u03pf8|0010D1E61973|UNEP_Labs|ADDITIONALS|COMMENT|9C39D8A9-5A91-427A-A659-2AAF556ACF52 |
