Popis: 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.

Popis: MAX phases are a family of ternary carbides and nitrides that share a similar layered hexagonal crystal structure. They are so called because of their chemical formula: M(n+1)AXn where n = 1, 2, or 3, where M is an early transition metal, A is an element from the IIIA or IVA groups, and X is carbon and/or nitrogen class of materials. MAX phases combine attractive properties of both ceramics and metals, and has been suggested for potential applications in nuclear reactor. The specific activities of Ti₃AlC₂ and Ti₂AlC were found to be similar to SiC, and are three orders of magnitude less than Alloy 617 after 10 to 60 years decay for all three activation times in both the fast and thermal spectra.

Popis: The amine-reactive portion of SPDP reagents is the N-hydroxysuccinimide (NHS) ester. Reactions are most commonly performed in phosphate, carbonate/bicarbonate, or borate buffers at pH 7-8. Other buffers can be used provided they do not contain primary amines (or thiols or disulfide reducing reagents – see discussion of the sulfhydryl reactivity). The rate of reaction and degradation by hydrolysis increases with increasing pH; for example, the half-life of the NHS ester is several hours at pH 7 and less than 10 minutes at pH 9. NHS-ester reagents like SPDP and LC-SPDP have limited aqueous solubility and must be dissolved in organic solvent before adding them to a reaction mixture. Sulfo-NHS-ester reagents like Sulfo-LC-SPDP are water-soluble and can be added directly to aqueous reaction mixtures.
