摘要： A centrifugal evaporator includes a chamber in which sample containers are carried and rotated by a rotor and are pivotally mounted so as to swing up to a substantially horizontal orientation as the rotor rotates. The evaporator includes an infra-red source to direct infra-red radiation towards the rotor and the sample containers carried thereon, to heat at least the latter and any sample material therein. A non-contact temperature sensing infra-red pyrometer having a sensor with a defined field of view is mounted in the chamber, such that while the rotor as such is substantially out of its field of view, each sample container at least partly occupies the pyrometer field of view for a part of each rotation of the rotor. The positions of the infra-red source and the pyrometer components are selected so that the radiation from the infra-red source does not impinge on the pyrometer sensor.

摘要： A centrifugal evaporator is described comprising a chamber in which sample containers are carried and rotated by a rotor and are pivotally mounted so as to swing up into a horizontal attitude as the rotor rotates. The evaporator includes an infra red source to direct infra red radiation towards the rotor and the sample containers carried thereon, to heat at least the latter and any sample material therein. A non-contact temperature sensing infra red pyrometer having a sensor with a defined field of view is mounted in the chamber, such that while the rotor as such is substantially out of its field of view, each sample container at least partly occupies the pyrometer field of view for a part of each rotation of the rotor. The positions of the infrared source and the pyrometer components are selected so that the radiation from the infra red source does not impinge on the pyrometer sensor. In particular the infra red source radiation predominantly impinges on the sample containers rather than the rotor. The position of the pyrometer sensor is chosen so that the rotor does not protrude into the pyrometer field of view. The direction of rotation of the rotor is such that any debris thrown from the rotor is directed away from the sensor. Temperature sensing means measures the temperature of the chamber, the pyrometer sensor body and the body of the chamber temperature sensor. Electrical signal processing means receives signals from the IR pyrometer sensor and the temperature sensing means to adjust the temperature values from the IR pyrometer sensor to take account of the chamber temperature, and sensor body temperature.

摘要： A method and sample holding assembly are described for use in the preparation of samples for analysis. The method comprises the steps of collecting a sample in a concentration tube which is open at one end and closed at the other, the closed end being selectively openable. A vial is coupled to the open end, the tube is inverted, the closed end is opened, and then solvent is evaporated from the sample via the opened end until the concentrated sample is confined to the vial. A sample holding assembly for use in the present method is also described. It comprises a concentration tube, and an adaptor arrangement for coupling a vial to the open end of the tube and defining a fluid path between the tube and the vial.

摘要： A method of controlling the pressure within a chamber (12) of a drying apparatus (10) from which air and vapour is removed by a pump (30), which is operated continuously during the drying process. If both of a vent valve (18) and a pressure control valve (32) is opened, air at atmospheric pressure is drawn by the pump (30) directly from the pressure control valve (32), and via the chamber (12) and a non-return valve (26) from the vent valve (18). When the pressure in the chamber (12) is to be reduced both vent and pressure control valves (18, 32) are closed to allow the pump (30) to remove air, gas and vapor from the chamber (12) via the non-return valve (26). After a required chamber pressure has been reached, the pressure control valve (32) is opened while the vent valve (18) remains closed.

摘要： A method and sample holding assembly are described for use in the preparation of samples for analysis. In known techniques, following concentration of a sample using an evaporator, the concentrated solution is manually transferred to a smaller vial compatible with analysis apparatus using a pipette. This leads to loss of the sample and risks cross-contamination. Using the present method, a sample is concentrated directly into the vial. The method comprises the steps of collecting a sample in a concentration tube which is open at one end and closed at the other, the closed end being selectively openable. A vial is coupled to the open end, the tube is inverted, the closed end is opened, and then solvent is evaporated from the sample via the opened end until the concentrated sample is confined to the vial. A sample holding assembly for use in the present method is also described. It comprises a concentration tube, and an adaptor arrangement for coupling a vial to the open end of the tube and defining a fluid path between the tube and the vial.
