Agilent ZORBAX Extend-C18 RRHT Threaded Column Datasheet
The Agilent ZORBAX Extend-C18 RRHT threaded columns are engineered for high-performance reversed-phase HPLC, featuring a patented bidentate organosilane bonded to ultra-pure silica support. This design provides exceptional stability at high pH levels, making them suitable for separating highly basic compounds as free bases. The columns utilize a proprietary high-pressure slurry-loading technique to ensure a uniform bed density and maximum efficiency.

Questions answered in these manuals
What is the maximum pressure rating for 4.6-mm ID columns?
4.6-mm ID columns support 16,000 psi (1000 bar) operation.
From: Agilent ZORBAX Extend-C18 RRHT Threaded Column Datasheet
Can these columns be used with high pH mobile phases?
Yes, they are designed for stable use with high pH mobile phases up to pH 11.5.
From: Agilent ZORBAX Extend-C18 RRHT Threaded Column Datasheet
What is the maximum pH for the Extend-C18 column?
The column can be used up to pH 11.5 with good results, provided organic buffers are used and the temperature does not exceed 40 C.
Is the Extend-C18 column suitable for separating basic compounds?
Yes, it is especially well-suited for separating highly basic compounds as free bases, which often produce poor peak shapes on other columns.
Which columns are used for EPA 8330 explosives separation?
The study uses ZORBAX Extend-C18 columns with Rapid Resolution High Throughput (RRHT) and Solvent Saver Plus configurations.

How does the 1.8 µm column compare to the 5 µm column?
The 1.8 µm column reduces analysis time and provides high resolution, though it generates higher back pressure.
