ReliableColumn-to-ColumnPerformance
Chromatographers need toknow every column they receive is going toperform in the sameway as the column it replaces.Rxi™-5ms
column technologyhas enabledus to tightenour quality control standards for passing columns, and guarantees column reproducibility.
Columns from threemanufacturingbatches show the excellent reproducibilityof retention times andpeak shape assuredby thenew
