DGT revolutionised the measurement of sulfide in sediments by providing a cheap, quick and easy way to obtain 2D images of its distribution. Calibration was not so easy as it involved conventional measurement of a substance prone to oxidation and volatilisation. We have overcome this problem by supplying pre-calibrated grey-scale strips. A detailed, easy to use, guide to the measurement of sulfide by DGT has also been added.
