Inspection Report

To give our customers an insight into the strict criteria with regard to the silica base, the derivatised final product and the reproducible chromatographic behaviour, each column of the ProFamily is supplied with a lot inspection report and an individual column test chromatogram. The first report illustrates the narrow window for physical parameters such as particle size distribution or surface area and the reproducibility of chemical properties. The test chromatogram illustrates the efficiency of the column with a guaranteed minimum performance of 100,000 theoretical plates for 150 and 250 x 4.6 mm i.d. and an asymmetry of 0.90 to 1.15 (at 10% peak height for 5 μm particle size).
