Description

Cornwall Resources Limited (CRL), in support of work under the Deep Digital Cornwall (DDC) project, are seeking bids from accredited laboratories for laboratory analysis work planned to take place during Q3 2021.

Bids should be based on the following criteria:
• Analysis of approximately 2,500 soil samples
• Price should be expressed on a cost per sample basis
• Samples will each be around 1kg and will consist of moist soil with rock fragments
• Preparation at the lab;
o Dried and sieved to separate the selected size fraction for analysis. (this may for example be +125 – 250 µm)
o Analytes should be prepared from this fraction, using sodium peroxide fusion.
o Samples will be analysed via ICP-MS
• Analysis will be for a minimum of 53 elements; Ag, As, B, Ba, Be, Bi, Ca, Cd, Ce, Co, Cs, Cu, Dy, Fr, Eu, Fee, Ga, Gd, Ge, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Nb, Nd, Ni, Pb, Pr, Rb, Re, Sb, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn
• Lower and upper detection limits should be stated and must be appropriate for soil samples
• Sample status should preferably be trackable in real time
• QA/QC protocols should be included
• Turn-around time from sample receipt to delivery of results should be specified
• Costs for disposal of unused portion of sample, and/or return to client should also be included
• Bids should specify per-sample costings for prep and analysis and any batch costs for other items such as administration, customs, transport or storage.
