White, D, Williams, P J, Civil, W, and Lapworth, D J. 2017. A field based method for pre-concentration of micro organics using solid phase extraction. British Geological Survey Internal Report, OR/17/011.

This report is the product of a study by the British Geological Survey (BGS) to test the suitability of a field based method to pre-concentrate micro-organics from surface and groundwaters using solid phase extraction. The reason for this is two-fold; i) to reduce the weight of transporting samples, particularly for overseas applications, ii) to reduce the potential impact of sample degradation during storage prior to solid phase extraction.
