    摘要: There is disclosed apparatus and a system for effecting testing on a sample, such as for medical testing. The apparatus includes a sample chip (30) provided with at least two chambers (48, 50) within which analyte and a sample to be tested can be located, one chamber being a mixing chamber (48) and the other a detection chamber (50), the latter being provided with a sensor or means to enable sensing of one or more parameters pertaining to the sample. A detector unit (70, 170) includes a slot (76) for holding a sample carrier (30), drive means (94) for moving parts of a sample from the mixing chamber (48) to the detection chamber (50), such as by electromagnetic force, sensing means (60) for sensing the one or more parameters, a diagnostic unit (84) for analyzing the sensed parameters and a display unit (72) for displaying the results of the test to a user. The test unit (70, 170) is preferably handheld, which the sample carrier (30) is preferably in the form of a disposable chip.

    摘要: A method for determining the presence or amount of a metal-labelled analyte (12) in a sample is described. The method comprises the steps of adding a release agent (20) to the metal labelled analyte (12) to release the metal label (18) from the analyte (12), the release agent (20) forming a charged stable species (22) with the metal label (18), applying a potential to bring the charged stable species (22) to an electrode (22), dissolving the charged stable species (22) under a positive potential to form metal ions (26), and carrying out a quantitative determination procedure such as anodic stripping voltammetry to determine the presence or amount of the metal-labelled analyte (12).

    摘要: A system (100) uses a pyroelectric membrane (122) and an ultrasound absorber (123) to measure the amount of ultrasonic energy received from a transmitter (105) through a sample (110). The thermal response of the pyroelectric membrane (122) is sensitive to ultrasound time-averaged intensity but is insensitive to the phase of the ultrasound. A waveform (200) shows rising (210), peak (220) and decaying (230) portions of a signal from the pyroelectric membrane (122) in response to on/off transitions of the transmitter (105). A system (300) uses a peak detector (333) to automatically turn the transmitter (105) on/off. A system (400) has background removal circuitry (444) to remove unwanted accelerometer-induced noise or electrical noise. A multi-element ultrasonic sensor (520) has cavities (555) so that a dummy sensor (521 b) can be used to compensate for unwanted accelerometer sensitivity of a sensor element (521 a). A sensor (620) has ultrasound absorbing (or reflective) regions (660) to compensate for unwanted accelerometer sensitivity. A system (900) has a low frequency path (909) sensitive to the pyroelectric effect, and a high frequency path (919) sensitive to the acoustic pressure amplitude, of a signal from a sensor (920). A sensor (1020) uses a pyroelectric material (1022) with poled regions (1099) separated by a non-poled region (1098).
