Performance Guarantee and Validation Kits
Guaranteed Packing Materials
The strict quality control system of Nacalai Tesque supports customers with an individual Inspection Report, which accompanies each and every COSMOSIL, COSMOGEL, and COSMOCORE packed column (except guard columns), and an additional Certificate of Analysis for the packing material of the below products.
Columns for Validation
The below columns are available in 3-lot method validation kits to demonstrate high reproducibility. Please contact us for information on other products.

COSMOSIL Certificate of Analysis
Tested items include physical properties of the silica gel, carbon content, metal content, polar selectivity, hydrophobicity, silanol capacity, steric selectivity, and inertness to basic and chelating compounds.
Certificate of Analysis for 5C18-MS-II
The Inspection Report is included with every COSMOSIL packed column to guarantee high quality. You can use our strictly controlled products with confidence.
Sample Inspection Report

- Peak asymmetry
- Capacity factor
- Separation factor
A period of more than 30 years has passed since the first COSMOSIL 5C18 columns were developed. Continuous technical improvement has made many of these columns obsolete. However, many long-term users continue to employ these older columns for routine analysis and quality control. Nevertheless, the manufacture of these products will eventually cease, and we strongly urge customers to replace these legacy columns with their higher-performance equivalents outlined in the table below.
