SUPELCOSIL™ LC-NH2 Supelguard™ Cartridges are high-performance liquid chromatography (HPLC) guard cartridges that are designed to protect analytical columns from contamination. The cartridges are made with a 5 ?m SUPELCOSIL packing and a 2 cm stainless steel body that is enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 ?m porosity). This design ensures that the cartridges are able to provide excellent performance and reliability. The cartridges are available in two sizes: 2 cm ? 4 mm and 2 cm ? 3 mm. The 2 cm ? 4 mm cartridges are a good choice for protecting analytical columns containing 3 ?m particles, while the 2 cm ? 3 mm cartridges are a good choice for protecting analytical columns containing 5 ?m particles.
