YMC America, Inc Triart Phenyl 120A 5um 30x10mm
YMC-Triart phases are based on organic/inorganic hybrid particles that combine the high mechanical stability and efficiency of a silica-based packing material with the robust chemical stability of a polymer-based packing material This versatile resin is produced using tightly controlled particle formation technology adapted from micro-reactor technology The resulting uniform particle and pore size distributions as well as the smooth surface greatly contribute to excellent peak shape and separation reproducibility In addition YMC-Triart materials are highly resilient and robust when used at extreme pH elevated temperature and high pressure
Perkin Elmer US LLC Brownlee Aquapore ODS RP-18 NewGuard Cartridge - 15 mm x 3.2 mm I.D., Pkg. 3
Aquapore ODS RP-18 NewGuard cartridges are based on a spherical silica support suitable for the separation of large biopolymers. These cartridges prolong column life by 2 to 5 times while protecting columns from particulates and strongly bound sample components. Actual bed length of each 15 mm NewGuard is approximately 13 mm. These NewGuard Cartridges require a holder: To couple with a conventional column - NewGuard Holder (07150001) To couple with an MPLC cartridge - Union (07150018) Quantity: Package of 3 Interaction Mode: Reversed Phase USP Code: L1
Perkin Elmer US LLC Brownlee NewGuard Cartridge Holder
This holder can be used to couple any NewGuard directly to any LC column.
YMC America, Inc SIL guard 60A 5um 20x4mm
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery The absence of silica impurities reduces non-specific sample adsorption and the totally porous nature of the silica provides high sample loading The elevated chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength YMC-Pack SIL is suitable for separation of fat-soluble compounds using non-polar mobile phases as well as the separation of positional isomers that are difficult to separate in reversed-phase mode SIL-06 (60 pore size) has greater adsorption properties than SIL (120 pore size) due to its larger surface area and is generally useful for separating natural products with low molecular weight
