Inorganic geochemistry reference materials

Preparation of reference materials at the BGS

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 BGS110 to BGS119 each have data sheets 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.

BGS102 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: Hamilton et al., 2015. Microchemical Journal, 123. 131-138. https://doi.org/10.1016/j.microc.2015.06.001

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.

How to purchase reference materials

For purchasing, and more information on the reference materials, please contact the inorganic geochemistry team with details of the specific reference materials of interest to you. A quotation for supply will be provided, incorporating packing/postage charges (detailed below). On approval of the quotation, you will be contacted regarding payment options. These items cannot be ordered and paid for directly from the online BGS shop.

Packing/postage is added as follows:

Tracked UK delivery: £15.00
Tracked European delivery: £25.00
Tracked worldwide delivery: £35.00

All prices quoted exclude VAT at the applicable rate.

Sterilised samples of BGS110 to BGS119 (by gamma irradiation of at least 50 kGy) are available on request for supply to countries outside of the UK.
