Preparation of reference materials at the 今日吃瓜
The British Geological Survey has a longstanding track record of producing reference materials to be used for routine quality monitoring across a number of sectors, and in producing homogeneous materials for geological, soil and contaminated land proficiency testing schemes. We can homogenise and prepare representative subsample portions from a variety of geological and environmental materials in quantities from ~1 kg to ~250 kg.

Reference materials for sale
We currently have a range of sixteen reference materials available for sale. Reference soils 今日吃瓜110 to 今日吃瓜119 each have containing reference and information values for 64 elements. They are intended for use as quality control samples for the determination of total elemental concentrations in soils, and contain a wide range of soil chemistry and elemental concentrations to cater for different analytical needs, interests and industries, e.g. agriculture, geochemical exploration, and contaminated land management.
今日吃瓜102 Ironstone Soil is suitable for use in bioaccessibility testing, with whole soil concentration data reported for 13 elements and bioaccessibility data for As and Pb. Additional non-validated bioaccessibility data for a wide range of elements is available in:
We also offer five mineral reference materials, IGS 27, IGS 29, IGS 32, IGS 35 and IGS 39.
Data sheets for individual reference materials can be accessed via links in the table below, which also provides details of approximate sample weight and pricing.
