The optimum light level is adjusted automatically to compensate for lamp degradation and flow cell staining. A thermal design that allows initial setup in less than two hours, typically; warm-up of the module is generally less than one hour for fast startup. A recycle valve that can be switched on to keep the system at operating conditions avoiding any warm-up time and saving solvent. Early maintenance feedback (EMF), with user-settable limits for continuous tracking of the reference flow cell purging. Built-in GLP/GMP compliance, such as operational qualification/performance verification (OQ/PV) maximize productivity. Automatic purging of the reference flow cell by applying user-settable purge and wait times. For unattended operation autozero can be programmed as part of the method.
