What is zorbax eclipse?
ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns are eXtra Densely Bonded (XDB) and double endcapped through a proprietary process to cover as many active silanols as possible.
What is XDB C18 column?
Datasheet. General Description. Eclipse XDB-C18 utilizes the technologies of eXtra- Dense Bonding (XDB) of organo-silane ligands and double endcapping to protect the ultra-pure (Type B) silica support from dissolution in mobile phases of in- termediate and higher pH.
How does reverse phase work in HPLC?
Reversed-Phase HPLC The reverse phase chromatography principle affirms that the separations in reverse phase chromatography rely upon the reversible adsorption/desorption of solute molecules with changing levels of hydrophobicity to a hydrophobic stationary phase.
What is SB C18 column?
ZORBAX Rapid Resolution High Definition (RRHD) SB-C18. threaded columns are specially designed for use with ultra-high. performance liquid chromatographs (UHPLCs) such as the Agilent. 1290 Infinity LC and can be used up to an operating pressure of. 1200 bar.
Why zorbax eclipse XDB columns?
Because ZORBAX Eclipse XDB columns solve many of their separation challenges. In fact, Agilent Technologies includes a 4.6 × 150 mm, 5 µm ZORBAX Eclipse XDB column with every Agilent 1100 HPLC instrument it delivers.
What is the particle size of zorbax XDB C18?
(p/n 993967-902) C. ZORBAX Rapid Resolution Eclipse XDB-C18 4.6 ×75 mm, 3.5 µm (p/n 966967-902) Eclipse XDB columns, available in 1.8, 3.5, and 5-µm particle size packings, are highly efficient.
What is the water flow rate of the zorbax eclipse xdb-c18?
4.6 ×150 mm, 5 µm p/n 993967-902 Mobile phase: 60% Methanol 40% Water Flow rate: 1 mL/min Temperature: 25 °C Column: ZORBAX Eclipse XDB-CN 4.6 ×150 mm, 5 µm p/n 993967-905 Mobile phase: 60% Methanol 40% Water Flow rate: 1 mL/min Temperature: 25 °C Column: ZORBAX Eclipse XDB-C18
What is eclipse xdb-c18 made of?
The uniform, spherical Eclipse XDB-C18 particles are based on ZORBAX Rx-SIL silica support that has a nom- inal surface area of 180 m2/g and a controlled pore size of 80Å. Columns are loaded to a stable, uniform bed density using a propri- etary, highpressure slurry-loading technique to give maximum column efficiency.
