2.3.3 Installing the column stabilizer assembly
If your application requires passive preheating using the column stabilizer, you must remove the
APH assembly and retainer from the column-heater compartment and install the column-stabilizer
assembly.
Notice:
Waters does not recommend using the column stabilizer with normal-phase
solvents, including the following and other similar solvents: tetrahydrofuran (THF),
methylene chloride, ethyl acetate, chloroform, hexane, heptane, octane,
trichlorobenzene (TCB), dimethyl sulfoxide (DMSO), toluene, hexafluoroisopropanol
(HFIP), and N-methly-2-pyrrolidone (NMP) due to the chemical compatibility of the
thermal gasket.
Requirement:
If the CH-A is fitted with an APH assembly, you must uninstall the APH assembly
from the column-heater compartment before you install the column-stabilizer assembly. Also,
before operating the system, you must change the column preheater setting in the console to
Active, disabled
. For instructions, see
Specifying the preheater setting
Warning:
To prevent burn injuries, set the column temperature to Off, and then allow
the column compartment and its components to cool for 60 minutes before touching
them. Monitor the column compartment's internal temperature to ensure that all
components are cool.
Warning:
To avoid personal contamination with biologically hazardous, toxic, and corrosive
materials, wear chemical-resistant, powder-free gloves when performing this procedure.
Warning:
To avoid eye injury, use eye protection when performing this procedure.
Required tools and materials
• Chemical-resistant, powder-free gloves
• Protective eyewear
• Needle-nose pliers
• #1 Phillips screwdriver
• 1/4-inch open-end wrench
• 1/2-inch open-end wrench
• Column gripping tool
• Column stabilizer kit
The figures below represent the tubing connections and components required for a CH-A column-
stabilizer configuration.
