Preparation of 2-amino-2-hydroxymethyl-1,3-propanediol (TRIS) pHT buffers in synthetic seawater
Buffers of known quality for the calibration of seawater pHT measurements are not widely or commercially available. Although there exist published compositions for the 0.04 mol kg-H2O−1 equimolar buffer 2-amino-2-hydroxymethyl-1,3-propanediol (TRIS)-TRIS · H+ in synthetic seawater, there are no explicit procedures that describe preparing this buffer to achieve a particular pHT with a known uncertainty. Such a procedure is described here […]
