MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-DP Supelguard Cartridge Kit, 5 μm Particle Size

Contains a diphenyl bonded phase, which gives greater selectivity for aromatic groups compared to alkyl-type bonded phases.

4

MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-NH2 Supelguard Cartridge Kit, 5 μm Particle Size

SUPELCOSIL™ LC-NH2 Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).

5

MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-1 Supelguard Cartridge, 5 μm Particle Size

Due to a mixed retention mechanism, selectivity differences for polar groups are more pronounced than on C8 and C18 columns. C1 columns require 20-30% less organic modifier to provide retention similar to C18 columns.
