The P/ACE is a state-of-the art computer-controlled instrument, providing automation to most steps of the analysis. It is important, however, to understand the components of the instrument to ensure successful operation and reliable results.
Vials containing buffer, cleaning, and sample solutions are held in this units concentric carousels. The outer carousel serves the inlet end of the capillary, while the inner carousel serves the outlet of the capillary. Access to the capillary coolant reservoir is also near the carousel. This coolant circulates around the capillary to help minimize the detrimental affects of heating of the capillary.
B. Instrument Controls and Status Indicators
While most of the instrument control functions are controlled by computer through the CE software, these manual controls and indicators are still useful. The digital display allows real-time viewing of parameters such as separation voltage and current, and detector response. While an experiment is running, the indicators show the current operation that is being executed. The carousel control buttons are used to manually position the carousel for sample loading and unloading.
A black cartridge houses the separation capillary. Typically this is a coil of silica capillary 50-75 cm long. Near the end of the capillary, a portion of the plastic coating on the capillary is removed to serve as a window for the optical detection scheme.
Each end of the capillary extends toward the carousel to allow interaction with the inlet and outlet vials.
Once the appropriate vials are positioned at the capillary inlet and outlet, pressure from a compressed gas cylinder (typically nitrogen) is applied inside the carousel. This pressure increase causes the vials to raise and allows the solutions to make contact with the capillary ends and the cathode and anode.
The P/ACE system is capable of utilizing three different detection schemes: UV absorbance with photomultiplier tube detection, UV absorbance with photodiode array detection, or detection by laser-induced fluorescence. Each option is housed in its own module and can readily be removed and switched, depending on your needs. This unit powered up and serviced last by Dow Agro Sciences.
