Risultati analitici
These two sets of chromatograms show separations on 100, 50, 30, and 20 mm x 2.1 mm I.D. columns and at different flow rates and demonstrate the utility of the 1.9 μm Titan particles. The highest grade solvents provided clean, robust operation. Cerilliant CRMs provided reliable quantification.
