摘要： The invention concerns a device for picking up liquid samples to be analyzed, especially in automatic samplers, said device comprising a needle connected to a sucking pump and supported by a support which moves said needle downwards to pick up the sample from a vial containing same and upwards from said vial. In order to perform a washing step after one aspiration and before the subsequent one, the needle support is designed to perform an oscillating movement when the support is in its upward position with respect to the vial. The oscillating movement is performed by the cooperation of cam means and a control rod having at least a pivot axis controlling the alternative movements. The oscillating movement makes the needle plunge into a sidewardly positioned trough containing a washing liquid.

摘要： This invention concerns a chamber for chromatographic analyses, in which capillary columns, in particular columns of fused silica, are thermally conditioned. The chamber comprises a thermally insulated space which can be perfectly sealed towards the outside and which houses means for heating the air and at least a fan for air circulation inside said space. In order to make the air flow going to the column(s) within the chamber as homogeneous and stable as possible from the thermal viewpoint the heating means are positioned on the suction side of the fan or of each fan, so to cause a perfect mixing of cold and hot fluid flow threads or lines in correspondence with the fan itself, and thereby obtain a uniform and stable air current from the fan towards the column.

摘要： A method for performing porosimetric analyses and apparatus therefor are disclosed. In particular, a method for performing porosimetric anaylses by the so-called mercury method is disclosed, wherein volumetric variations of mercury placed in a vessel are recorded. These variations are due to mercury penetration into the pores of a solid sample placed in the vessel under the mercury pressure variations. In the method disclosed, additional porosimetric information is obtained by reducing the pressure from a maximum value as a predetermined function of time. For example, the pressure reduction can be at a constant rate. Simultaneously, volume variations of the mercury exiting the sample pores are detected as the pressure decreases. This additional detection, when performed in relation to and/or in addition to the traditional measurement during pressure increase, provides a pressure/volume mercury curve which gives further data on the porosimetric characteristics of the sample, in particular related to the shape of the pores in the sample.
摘要翻译：公开了一种进行孔隙率分析的方法及其装置。特别地，公开了通过所谓的汞法进行孔隙率分析的方法，其中记录放置在容器中的汞的体积变化。这些变化是由于汞在汞压力变化下渗透到容器中的固体样品的孔中。在所公开的方法中，通过将压力从最大值减小为预定的时间函数来获得额外的孔隙度信息。例如，减压可以是恒定的速率。同时，当压力降低时，检测出离开样品孔的汞的体积变化。当在压力增加期间相对于和/或除了传统测量之外执行该附加检测时，提供压力/体积汞曲线，其进一步提供样品的孔隙度特征的数据，特别是与孔的形状有关在样品中。

摘要： A device is disclosed for coordinating the position of an injection syringe needle in a gas chromatographic apparatus with at least one other operation of the gas chromatographic apparatus downstream of the device. The device comprises a first channel for introducing the injection syringe. The first channel is substantially aligned with the injection channel of a gas chromatographic injector. The device also includes a position sensor and a lever rotatable around a lever axis substantially perpendicular to the axis of the first channel, wherein the lever has an arm and a shaped appendix, wherein the shaped appendix protrudes into the first channel when the lever is in its rest position, and wherein the appendix is positioned so that, when an injection syringe is introduced into the channel past said point, the injection syringe contacts said appendix and causes rotation of the lever about the lever axis from its rest position so that the arm acts on the position sensor to indicate detection of the presence of the injection syringe in the first channel at said point. The device further includes at least one servomechanism actuatable in response to the detection of the syringe in the channel for controlling the other operation depending on whether or not the injection syringe is detected in the channel.

摘要： The invention relates to a modified-flame thermionic detector for gas chromatographs, of the type including a burner nozzle, an excitation electrode and a collecting electrode. The electrical connections of the nozzle and the excitation electrode can be changed at the operator's will, together with the spatial position of the excitation electrode with respect to the flame and the collector, to find out the presence of certain compounds, leaving all other conditions of analysis performance and detector supply unaltered. This allows obtaining chromatograms of unknown samples under different conditions of the detector configuration, to put into evidence the presence of certain compounds in the sample by comparing peaks of chromatograms obtained under said different operating conditions of the detector.
