Three Questions about solvents for Spectrophotometry and Fluorometry Ί. Which manufacturer offers the widest selection of high purity polar and non-polar solvents? 2. What manufacturing procedures are used to assure the quality of solvents for spectrophotometry and fluorometry? 3. Does it cost more to buy the best solvents for spectrophotometry and fluorometry?
Answers 1. MC&B (Spectroquality Solvents®) 2. MC&B research has developed specialized techniques for removing foreign chromophors and fluorophors* from Spectroquality solvents. The utility of these solvents is further enhanced by the removal of excessive residues and moisture. Purity is maintained by packaging, under an inert gas, in the exclusive MC&B Crown and Cap bottle. *Spectroquality benzene, toluene, glycerol, nitromethane, and carbon disulfide are not certified for use in fluorometry; however, benzene and toluene, suitable for this t e c h n i q u e , are available under separate listings S 2 7 3 8 and S5037 respectively.
3. MC&B Spectroquality Solvents are priced slightly higher than most competitive products. However, consistently superior quality make Spectroquality Solvents the most economical solvents to use. Write for free wall chart showing UV, IR, and Near IR transmittance of MC&B Spectroquality Solvents.
