N,N-Dimethyl-p-phenylenediamine dihydrochloride (DMPD) has been used in the HID-AB (high iron diamine-alcian blue) staining of intestinal tract samples. N,N-Dimethyl-p-phenylenediamine dihydrochloride (DMPD) is used for the determination of peroxidase. DMPD is converted into a red pigment of semiquinone nature. It is also used in the HID-AB (high iron diamine-alcian blue) staining procedures, which are used to differentiate between sialomucin and sulfomucin in the gastrointestinal tract.

Spectromelt® A 14 51% di-lithium tetraborate/ 27% lanthane(III) oxide/ 12% lithium metaborate/ 10% lithium fluoride for XRF (X-ray fluorescence), Supelco®

Supplier: Merck

Spectromelt is based on lithium borates for fluxing digestion as granulate or as fused material used for X-ray fluorescence analysis (XRF).
The fused particles are spherical, have a small particle size distribution and a higher bulk density.
The material is easy to handle and has a low loss on ignition.
