 r1 \section{Cell Assembly}\label{cellassembly} AUC cells for the An-50 Ti and An-60 Ti are most easily assembled when using the assembly tools shown in Figure \ref{fig-tca}.\begin{figure}[htbp]\begin{center}\includegraphics[width=0.7\linewidth]{section-cells/CellAssemblyTools.png}\caption{Required tools for cell assembly.}\label{fig-tca}\end{center}\end{figure}\\ \indent Also very convenient is a nitrogen pistol and a table for assembling and filling cells. For an example see Figure \ref{fig-npt}.\begin{figure}[htbp]\begin{center}\includegraphics[width=0.6\linewidth]{section-cells/CellAssemblyCorner.png}\caption{Convenient cell assembly facility. Panel A shows an overview (from left to right) of the table with a balance, rotors on their stands, cell assembly table with a hang-up for a nitrogen pistol (panel B) and the collet for torquing cells (also see Figure \ref{fig-twc}).}\label{fig-npt}\end{center}\end{figure}\\ \indent The windows are assembled as shown in Figure \ref{fig-wha}. The window gasket should be checked and changed when it becomes transparent indicating compression (Figure \ref{fig-wha}). The window liner is placed so that the open end is opposite of the alignment mark and the window inserted as shown with the arrow lined up with the keyway. The window should fit snuggly and the liner changed if it does not.\begin{figure}[htbp]\begin{center}\includegraphics[width=0.35\linewidth]{section-cells/WindowHolderAssembly.png}\caption{The assembly of the window in the holder. Window gaskets need to be changed periodically. Check to see if it has become transparent from compression.}\label{fig-wha}\end{center}f\end{figure}\\ \indent The bottom window assembly is pushed down to the bottom of the housing, window side up aligning the keyway with the key, the centerpiece inserted part number right side up, and the top window assembly inserted (Figure \ref{fig-scwas}).\begin{figure}[htbp]\begin{center}\includegraphics[width=0.5\linewidth]{section-cells/StackingCenterpieceWindowAssySpacers.png}\caption{Stacking a standard double-sector centerpiece (left) or a 3-mm centerpiece, window assemblies with or without spacers.}\label{fig-scwas}\end{center}\end{figure}\\ \indent Place the screw ring gasket and screw ring into the top and torque to 120 in-lbs (inch pounds). Over torquing may result in the warping of the cell or crushing of windows.\begin{figure}[htbp]\begin{center}\includegraphics[width=0.6\linewidth]{section-cells/AssemblyOfSixChannelCells.png}\caption{The assembly of six-channel cells. The bottom centerpiece is inserted from the bottom as shown and a window assembly placed in position. A screw ring gasket and screw ring are tightened to 60 in-lbs (inch pounds). The cell is inverted right side up and the part number placed to the left. The front row holds the reference buffer while the back row holds the three samples. The top window assembly is inserted and the top screw ring gasket and screw ring positioned and torqued to 120 in-lbs (inch pounds). The center of the keyway is used to align the cell in the rotor as there are no scribe marks.}\label{fig-ascc}\end{center}\end{figure}\\ \indent Cell housing for 6-channel centerpieces have screw rings on both sides (Figure \ref{fig-ascc}) unlike housing for 2-channel centerpieces. The centerpiece is inserted as shown in Figure \ref{fig-ascc} and the bottom window assembly is added. The screw ring gasket and screw ring and put in place and tightened to 60 in-lbs (using a torque wrench with a collet). The reference and samples are added as described and the top window inserted and then the screw ring gasket (screw ring washer) and screw ring (Figure \ref{fig-chsrw}). The entire assembly is torqued to 120 in-lbs (inch pounds) using a collet to hold the cell and a torque wrench for tightening (Figure \ref{fig-twc}). Use of SpinKote$^{\circledR}_{}$ aids in the proper torquing of the cells, but should be used sparingly.\begin{figure}[htbp]\begin{center}\includegraphics[width=0.3\linewidth]{section-cells/CellHousingScrewRingWasher.png}\caption{The screw ring washer and screw ring.
