Thank you for choosing a Viridis
®
SFC column. The Viridis SFC packing
materials are designed to provide excellent stability, minimal column
bleed, and high mass loading. The Viridis SFC packing materials are
manufactured in an ISO 9000 certified plant using ultra-pure reagents.
Each batch of Viridis SFC material is tested and the results are held to
narrow specification ranges to assure excellent, reproducible performance.
Every column is individually tested and a Performance Chromatogram is
provided with each column along with the Certificate of Batch Analysis.
