Waters Corp Atlantis T3 Prep Guard Cartridge, 100Å, 5 µm, 10 mm X 10 mm, 1/pk
Atlantis T3 columns are universal, silica-based, reversed-phase C18 columns that provide balanced retention of polar and hydrophobic molecules and should be your first choice when developing separations of polar and non-polar compounds.
Waters Corp XTerra MS C18 Sentry Guard Cartridge, 125Å, 3.5 µm, 2.1 mm X 10 mm, 2/pk
XTerra MS C18 columns are general purpose, hybrid-based, reversed-phase C18 columns that are designed to be compatible with mass spectrometry applications. These first generation columns provide superior pH stability compared to a silica-based column.
Waters Corp Atlantis T3 Prep Guard Cartridge, 100Å, 10 µm, 10 mm X 10 mm, 1/pk
Atlantis T3 columns are universal, silica-based, reversed-phase C18 columns that provide balanced retention of polar and hydrophobic molecules and should be your first choice when developing separations of polar and non-polar compounds.
Tosoh Bioscience LLC GD CART TSKGEL AMIDE-80(3) 3/P
LC Guard Cartridges, Guard Cartridge for 2 mm ID TSKgel Amide-80 columns, 3 um, 3 pk
GL Sciences Inc Inertsil ODS-3, 3 Micron, Conventional Guard Column, 10 X 4.0mm
Virtually perfect peak shape for most bases and acids. Predictable selectivity with very low operating pressure making this ideal for fast/LC, UPLC, and LC/MS. Exceptional physical and chemical durability provides long column life. Vast database of chromatographic applications available to assist in method development.
Waters Corp XBridge BEH C18 Prep Guard Cartridge, 130Å, 10 µm, 10 mm X 10 mm, 1/pk
As a workhorse for HPLC method development, XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1-12). The trifunctionally bonded C18 ligand provides you with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed.
Waters Corp XBridge BEH Shield RP18 Prep Guard Cartridge, 130Å, 5 µm, 19 mm X 10 mm, 1/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.
Waters Corp XBridge BEH C8 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk
The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent. Anyone developing methods may prefer the speed offered by a less retentive column, while improving peak shape and chromatographic performance. The trifunctionally bonded sorbent offers you the widest usable pH range (1-12), superior low pH stability, and ultra-low column bleed.
Waters Corp SunFire C8 Prep Guard Cartridge, 100Å, 10 µm, 10 mm X 10 mm, 1/pk
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
Waters Corp SunFire C8 Sentry Guard Cartridge, 100Å, 5 µm, 4.6 mm X 20 mm, 2/pk
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
Waters Corp Spherisorb C8 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb C8 columns are general purpose, silica-based reversed-phase columns that contain an Octyl ligand. These USP L7 columns are used when you require a less retentive sorbent compared to the Spheriorb ODS columns.
