    4 In the following sections various parts of the Beckman Optima XL-A/I AUC are discussed. A protocol to check the performance of the Beckman Optima XL-A AUC (absorbance optics only) can be found in Appendix \ref{protocolperformancecheck}. You may find it useful to read Chapter 2 of the PhD thesis \textit{Analytical Ultracentrifugation of Inorganic Colloids} \cite{aucicplanken} for a detailed discussion on the Beckman Optima XL-A/I instrument and the basic experiments that can be performed with this AUC. Also practical tips on how to set-up and to perform your experiments can be found in that chapter. The thesis is, free of charge, accessible via the internet (click \textit{here} to navigate to the latter document, Adobe$^{\circledR}_{}$ Reader$^{\circledR}_{}$ 5.0 or higher required).

    67\section{Chamber}\label{chamber}A high strength structural steel door covers the chamber and can be opened with the power on and the vacuum off. The inside chamber is constructed of epoxy-coated aluminum with a drive spindle and safety plate visible on the bottom. The slit-assembly, required for the absorbance optical system, which is driven by a motor pot is integrated in the safety plate. Also on the bottom the condenser lens used in Rayleigh interference optical systems, the index pulse detector (Hall-effect sensor) which determines the rotor position, a photoelectric device which determines the maximum speed of the rotor based on the alternating reflective and non-reflective surfaces of the over speed ring, and the radiometer which is activated at a vacuum less than 100 microns (100 $\mu \text{m\, Hg}$) and measures the temperature of the rotor are visible. A thermistor (underneath the safety plate and therefore not visible) measures the temperature of the chamber above 100 microns. The monochromator mounting receptacle is positioned on the bottom of the chamber outside the safety plate.\begin{figure}[htbp]
