Frequently Asked Questions
1. What is the Macherey-Nagel CHROMABOND Sorbent C18 ec, 100g, Endcapped C18 SPE, 45µm, Glass Container used for?
It is designed for reversed-phase solid phase extraction, sample clean-up and enrichment applications using hydrophobic C18 retention.
2. What type of SPE chemistry does Macherey-Nagel CHROMABOND C18 ec use?
It uses an endcapped octadecyl-modified silica phase, commonly referred to as C18 or RP18 chemistry.
3. What particle size and pH stability does Macherey-Nagel CHROMABOND C18 ec provide?
It uses 45µm silica particles and has a specified pH stability range of 2.0-8.0.
4. Why choose the bulk format of Macherey-Nagel CHROMABOND C18 ec?
The 100g loose sorbent format allows laboratories to prepare customised SPE packing configurations.
5. How does the Macherey-Nagel CHROMABOND Sorbent C18 ec, 100g, Endcapped C18 SPE, 45µm, Glass Container compare with the Supelco Supelclean LC-18 SPE Bulk Packing, 100g?
Both are real 100g bulk C18 reversed-phase SPE sorbents. The Macherey-Nagel product uses endcapped 45µm C18 silica with published carbon-content and surface-area specifications, while Supelclean LC-18 is a directly comparable C18 bulk packing option from Supelco.
