What is zorbax eclipse?
Agilent ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns provide good peak shape over a wide pH range (2–9) for additional method development flexibility with one family of columns.
What is C8 and C18 column?
C8 and C18 both refer to the alkyl chain of a bonded face of a column. They are both used in the high performance liquid chromatography system. On the other hand, Octylsilane(C8) has only 8 carbon atoms on the column parking bonded to silica (Si). C18 will tend to retain more than C8.
What is ODS C18?
Reversed-Phase C18 Columns (ODS) 78. 06. Octadecyl-silica (ODS) is the industry standard packing material for HPLC applications. YMC offers packing materials with an impressive assortment of functional groups for liquid chromatography and a selection of ODS columns that is far ahead of all others in variety.
What is the difference between agagilent zorbax RX-SIL columns?
Agilent ZORBAX RX-SIL columns have less acidic silica than ZORBAX-SIL, with lower metal content, which make them ideal for normal-phase separations of polar compounds that exhibit poor peak symmetry on more acidic silica. ZORBAX Rx-SIL is useful for very hydropholic compounds with high organic mobile phases in HILIC mode.
What is the size of the adsorption column in Agilent zorbax?
Agilent ZORBAX SIL uses proprietary ZORBAX SIL to create a high performance adsorption chromatogaphy column. IDs: 2.1 mm, 4.6 mm, 9.4 mm, 17 mm, 21.2 mm
Which zorbax columns are tested before shipment?
Every normal-phase column is tested before shipment and shipped in a normal-phase test eluent, with the exception of ZORBAX Eclipse XDB-CN, InfinityLab Poroshell 120 EC-CN, InfinityLab Poroshell 120 HILIC, InfinityLab Poroshell HILIC-OH5, InfinityLab Poroshell HILIC-Z, and ZORBAX HILIC Plus columns which are shipped in reversed-phase solvents.
What is rx-c18 HPLC column?
Zorbax Rx/Rx-Sil HPLC Columns from Agilent ZORBAX Rx columns are made from pure porous silica microspheres and are optimized for high throughput analysis. Rx-C18 is recommended for alternate selectivity at low pH relative to Eclipse XDB-C18 and StableBond SB-C18.
