    This dataset of paper records holds details of analysis of all the sample batches (from both internal and external customers) analysed by the Analytical Geochemistry Laboratory of the BGS since June 1996. It was installed to underpin the UKAS (United Kingdom Accreditation Service) accreditation of the geochemistry laboratories at Keyworth, which was awarded in August 1999. There is a file for each batch of samples submitted for analysis. The file documents the progress of the samples through the laboratories, including sample registration, sample processing, raw data from analytical instruments and the data reported to the client. The records are archived to provide supporting evidence for any query regarding geochemical data provided by the laboratories.

    This dataset contains records of the BGS analytical chemistry laboratories prior to the year 2000. It is basically an archive of original records and includes card indexes, files and raw analytical data. Files may contain background detail on the samples themselves but coverage is variable; information has been collected over many years in different formats. Different analytical techniques have been used over the years; consequently data are of variable quality as systems have improved with time. Samples analysed could be from anywhere in the world and were usually analysed for internal BGS customers. These are paper records and are available for viewing or copying. Any constraints on data usage would be dependant on individual files. Anyone wishing to access the records would require assistance from staff familiar with the data.
