一般描述
Discovery® C18 Supelguard™ Guard Cartridges [Kit, 5 μm particle size, L × I.D. 2 cm × 4 mm] contain a Discovery® packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity). A Supelguard kit (one cartridge, a stand-alone holder, tubing, and 2 nuts and ferrules) enables one to use the cartridge with any analytical column. A direct-connect guard cartridge holder can directly connect a Supelguard cartridge to a Supelco analytical column. 3.0 mm cartridges are available in packs of two only-purchase a stand-alone or modular holder separately. Low volume 3.0 mm ID cartridges are a good choice for protecting an analytical column containing 3 μm particles.
附注
套件包括一个保护柱芯、一个独立式保护柱套、一段管路、2 个接头螺母和密封垫圈。

A highly sensitive and selective on-line two-dimensional reversed-phase liquid chromatography/electrospray ionization-tandem mass spectrometry (2D-LC-ESI/MS/MS) method was developed and validated to determine rifaximin in rat serum by direct injection. The 2D-LC-ESI/MS/MS system consisted of a restricted access media column for trapping
