The UK Health & Safety Laboratory provides screening for urinary hexamethylenediamine (UHDA), a biomarker of exposure to 1,6-hexamethylene diisocyanate (HDI).

The high-frequency reorientation dynamics of O–H bonds is investigated in various amorphous ices including eHDA (expanded high density amorphous ice), LDA-II (low density amorphous ice II) and HGW (hyperquenched glassy water) using H-NMR spin–lattice relaxation as a local probe. Both low density forms, HGW and LDA-II, show similar spin–lattice relaxation but differ in the thermal stability with...
