Installation
• The direction of flow is marked on the column.
•  1.8 µm columns (ZORBAX RRHT, ZORBAX RRHD) can only be 
operated in the flow direction marked on the column.
•  InfinityLab Poroshell 120 columns may be operated in the opposite flow 
direction when cleaning the column. The frit porosity on the outlet of InfinityLab 
Poroshell 120 columns is smaller than on the inlet and can plug more easily.
 •  Agilent recommends InfinityLab Quick Connect fittings (5067-5961 for
0.075 x 105 mm) or Quick Turn fittings (5067-5966) for a perfect column 
connection, every time. Polyketone fittings (5042-8957) can also be used for 
columns up to 600 bar. 
Important Safety Considerations for all LC Columns
•  
All connection points in LC systems are potential sources of leaks. Users should 
be aware of the toxicity or flammability of their mobile phases.
•  
Because of the small particle size, dry column packings are respirable. Columns 
should only be opened in a well-ventilated area.
•   Adhere 
to operating pressure limits noted for each column (see chart on next 
page). Exceeding these limits will compromise chromatographic performance 
and could be unsafe.
