摘要： An X-Ray spectrometry detector comprises a detector head (1). The detector head is connected to a cold finger (8) of a stirling cycle cooling engine by a flexible coupling (11) to provide cooling for the detector head (1). The flexible coupling may take various forms including a metal braid or bellows.

摘要： Apparatus for transmitting an RF magnetic field pulse for use in an NMR or NQR experiment. The apparatus comprising a transmit antenna (10) for transmitting the RF magnetic field pulse and a switching element (12) such as a TRIAC which can be selectively switched on to couple a damping circuit to the transmit antenna. The damping circuit damps the transmit antenna by carrying a damping current. The switching element (12) is responsive to the damping current so as to switch off when the transmit antenna (10) has been damped to an acceptable level.

摘要： A method of obtaining information concerning the content of an experimental sample. The method comprises:
(i) irradiating a standard sample with X-rays and monitoring fluorescent X-rays emitted by the standard sample to obtain a correction coefficient I SID related to the intensity of the monitored X-rays. (ii) Irradiating the experimental sample under substantially the same experimental conditions as in step (i) with X-rays and monitoring fluorescent X-rays emitted by the experimental sample to obtain one or more experimental values I X , each experimental value being related to the intensity of the monitored X-rays corresponding to a particular analyte. (iii) Obtaining the information concerning the content of the experimental sample in accordance with an algorithm incorporating the experimental value I X , a calibration curve for the or each analyte and the correction coefficient I STD . The correction coefficient I STD is used to correct for any difference between the experimental conditions prevailing in steps (i) and (ii) and the calibration experimental conditions associated with the calibration curve.

摘要： Apparatus for monitoring a sample having 'solid' and 'liquid' content as hereinbefore defined, the apparatus comprising a magnetic field generator (3) for subjecting the sample to a static magnetic field in the first direction to cause the magnetic vectors of nuclei to precess about the first direction; means (2) for reorienting the bulk magnetic vector of the sample so as to gain a component in a plane orthogonal to the first direction and for monitoring the resultant FID; and a controller (8) for causing the apparatus to carry out the following steps.

i) Causing the bulk magnetic vector to gain a component in a second direction orthogonal to the first direction;
ii) after a first relaxation period less than the time for the 'solid' component of the resulting FID to decay to zero, causing the spins of the nuclei to rephase in such a way as to give an echo from which the 'solid' component in the sample can be determined;
iii) after a second relaxation period, following step (ii), and during which the part of the FID due to the 'solid' content of the sample decays to zero, causing the spins of the nuclei to rephase giving an echo arising from the 'liquid' component of the sample; and
iv) monitoring the resultant FID signal after step (ii) and after step (iii) to obtain a measure of the 'solid' and 'liquid' content of the sample.
