    4 Description of function Description of function This chapter explains the basic principle of the SpeedExtractor E-916 / E-914 and provides a functional description of the assemblies. Functional principle The SpeedExtractor E-916 / E-914 is an automated instrument for parallel extraction of primarily organic compounds from a variety of solid or semi-solid samples.
  • Page 23 4 Description of function a Main power switch The instrument is protected by a 14 A (240 V) circuit breaker. The main fuse button at the rear of the instrument must be pushed in. b Solvent reservoir The maximum possible number of solvent bottles depends on the type of mixer. With the 2-port mixer up to 2 different solvents, with the 4-port mixer up to 4 different solvents can be connected allowing any user-defined solvent ratios.

  • Page 24: Overview Of The Extraction Process

    4 Description of function Overview of the extraction process A complete extraction process involves the following phases: Phase 1: Preparation • Creating an extraction method (see section 6.2.3). • Preparing the instrument for operation. This involves filling the solvent reservoirs and preheating the instrument to the temperature of operation (equilibration), see section 6.2.3.

  • Page 25: Schematic Representation Of The Process

    4 Description of function cells is absolutely mandatory. Placing the cells in the cold instrument followed by heating up the closed system might damage the cup seals. It is therefore crucial to note that the temperature of the instrument must not be changed once the system is closed. The instrument is ready once the set temperature is reached (which is shown in the main display) and the extraction process is started by pressing START.

    6 Operation Extraction process Each extraction procedure occurs according to a set of predefined operating parameters such as pressure, temperature, flow rates etc. which are all part of the extraction method. The SpeedExtractor can store up to 100 methods. The optional PC software SpeedExtractor Record allows to create and manage an unlimited number of methods.

    6 Operation to 1/3 and 2/3 of the final pressure. The HEAT UP time is defined as the time during which the pressure remains at 1/3 of the total pressure. A further prerequisite is that the temperature of the heating block reached its equilibrium. It is a method-dependent intrinsic parameter which depends mostly on the size of the extraction cell and is therefore not adjustable by the operator.
  • Page 53 6 Operation Specify the vial volume: • Specification of the volume of the collection bottle is an important safety feature, since it alerts the oper- ator if there is a conflict with the total volume used for the subsequently defined extraction volume. The volumes of the most frequently used bottles (60 mL, 150 mL, 220 mL and 240 mL) are predefined.
  • Page 54 6 Operation Define the cycles: • Specify the number of cycles and go to the CYCLES submenu. The CYCLES submenu contains all cycles including their operating parameters such as HEAT- UP, HOLD and DISCHARGE time. There are only as many cycles shown as defined in NUMBER OF CYCLES.

  • Page 81: Replacement Of Check Valves

    8 Troubleshooting 8.1.5 Replacement of check valves The principle of a check valve is a precise ball and seat located in a casing of PEEK material with stainless steel reinforcement. By a stream of liquid the ball is pressed down to the seat, thus creating a seal. With respect to high pressures in the pump, any minute impurity stuck on the surface of the ball or the seat causes pressure fluctuation, or the pump fails to start at all.
