SCP reference standard
Although the use of SCPs as a means to identify contamination from industrially derived fossil-fuel combustion, or as a technique to provide chronologies for lake sediment cores and other natural archives, is now widely employed, the possibilities for intercalibration between analysts remains limited.
This 2008 paper suggested a set of standard criteria that could be used to positively identify SCPs under the light microscope and also introduced a sediment reference material for SCP analysis.
210 replicate SCP analyses were undertaken on an homogenized sediment sample compiled from a variety of lake sites. These replicate analyses resulted in an estimated mean SCP concentration of 6005 ± 70 SCP per gram dry sediment (gDM–1). More information is provided in the paper.
Small quantities of this sediment material are available on request to SCP analysts for the purposes of quality control. Please contact geog.lab@ucl.ac.uk.
