Notes

Diffusion coefficients have been selected taking into account in house measurements and literature values. Generally there are insufficient independent measurements between laboratories to view the values as definitive. These diffusion coefficients at 25oC, D25, can be converted to a value at any temperature, ToC, within the range 0 to 35oC, DT, using the equation below. This can be readily accomplished in an Excel worksheet.

The symbol* in the product code replaces the letters, N, L or P, indicating the three different plastic housings for solution device, soil device or sediment probe respectively. The last three letters in the product code indicate the binding gel, diffusive gel and the membrane filter material.

Binding gel (before the hyphen) C – XAD18; D – HLB; R – AC; W – WAX; T – TiO2
Diffusive gel (after the hyphen) A – agarose; N – polyacrylamide
Filter membrane (last letter) G – GHP; P – PES; T – PTFE

Abbreviations

HLB                            proprietary copolymer

AC                               activated charcoal

WAX                           weak anion exchanger

GHP                           hydrophylic polypropylene

PES                             polyethersulphone

PTFE                           polytetrafluoroethylene

We have only listed products where performance is proven with a robust DGT device. Some other products can be measured with some compromises. Please enquire whether we can meet your needs.
