29 Routine Operation and Limitations Routine Operation and Limitations Routine Operation Always filter freshly prepared washing solvents. Recommended mesh size is 0.47 mm or finer. If pure water is used, be aware of possible biological growth. To avoid biological growth, one can add an organic modifier. The maximum concentration allowed depends upon the application, but it should not exceed 15 vol% of methanol, 10 vol% acetonitrile, or 5 vol% 2-propanol. After refilling or changing the solvent(s) in the reservoir bottle, always use the priming functionality to ensure that all lines are completely bubble-free and that the solvent has been properly exchanged. If biological samples are analyzed, ensure that the first wash step is performed with aqueous solvent. The second wash step can be done with an organic solvent, but the final wash step must be with an aqueous solvent again. Not observing this procedure may lead to protein precipitation and as a consequence, clogging of the lines. The final wash step is important to prepare the system for the next sampling, and to ensure that the needle is free from protein precipitate. WARNING When filling-up standard reservoirs or replacing a solvent, such as a washing solvent, remove the solvent reservoir bottle from the system to avoid a possible spill over the instrument. Depending on the physical, chemical, and hazardous properties of the solvent, use the appropriate protective measures for handling. Limitations Currently, the following limitations are known: The Dilutor Valve is designed to bear a back-pressure of approximately 3 bar (300 kpa; 43.5 psig). In case of a higher back-pressure leakage of the valve may occur. The 7-Port Ceramic Dilutor Valve should not be operated with highly pure water otherwise a degradation of the Ceramic Structure may result. The Size of the Dilutor Syringe is limited to the following assortment of offered Syringe Sizes: 0.1 ml, 1 ml, 5 ml, and 10 ml. Thermo Scientific Dilutor Module for TriPlus RSH Instruction Manual 25
