Reichardt′s dye 90% (Farbstoffgehalt)

Lieferant: SIGMA ALDRICH MICROSCOPY

Beschreibung: Reichardt′s dye belongs to the class of azo merocyanine dyes. Reichardt′s dye, also known as ET(30) or pyridinium N-phenoxyde betaine dye is a highly solvatochromic betaine dye useful for determining solvent polarity effects. It plays an important role as a probe of solvent polarity in biological systems and on surfaces. Reichardt’s dye, a solvatochromic betaine dye has been used for the determination of solvent polarity.

Solid phase extraction cartridges, Bond Elut™ PRS

Lieferant: VARIAN

Beschreibung: Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.
