摘要： A device (100) for detecting a condition in a fluid system (14) and initiating a response based on the condition. The device consists of a sensor (12) that responds to a first and second condition of the fluid (13) in the system and a control means (10) that receives the responses and generates command signals in based on the received response. In a liquid chromatography system, the device is used to determine the volume of components of the fluid system. In addition, the device allow leaks to be detected and permits the fluid in the system to be transported at a optimum speed. The device is well implemented utilizing to a light emitter and light receptor that are sensitive to the fluid in either a gaseous or liquid state.

摘要： A device comprising a pressure monitor and a control means that receives a signal representing measured pressure at the pressure monitor and controls the controllable elements of a fluid system is utilized to monitor a fluid system for error conditions, to optimize operations and to diagnose the fluid system. By following a testing protocol that selectively enables parts of the system, the control means narrows the list of possible failing components. Comparing the measured pressure against normal pressures allows the device to identify error conditions. Determining the volume of fluid being transported and controlling the duration of the flow optimizes operation of the fluid system.

摘要： A method for processing a fluid is applied to systems that include a valve unit that has a sample-loading state and a sample-injecting state. The sample-loading state disposes a sample loop in fluidic communication with a sample conduit. The sample-injecting state disposes the sample loop in fluidic communication with a process conduit. The method involves transferring a sample through both the sample conduit and the valve unit so that a leading end of the sample exits the valve unit. After transitioning the valve unit to the sample-loading state and allowing the sample loop to decompress, at least some of the transferred sample is loaded into the sample loop. A fluid-processing instrument includes a value unit and a control unit that manages operation of the instrument. The control unit is configured, for example, to implement the above-described method.

摘要： Described is a method of transferring a chromatographic method between liquid chromatography (LC) systems. The method is based on a determination of an isoretention temperature at which two solutes co-elute. The method enables separations to be performed using different LC systems with reproducible and equivalent results. For example, the method allows for a chromatography method developed for HPLC to be more readily transferred to a UPLC system and for a chromatography method developed for a UPLC system to be more readily transferred to a HPLC system. The method addresses LC systems having column ovens of different design in which the internal column temperatures are not equal although the operating temperatures of the column ovens may be accurately controlled to equal values. The retention behavior and resolution of different LC systems is caused to be substantially the same so that equivalent separation results are obtained.
摘要翻译：描述了在液相色谱（LC）系统之间转移色谱方法的方法。该方法基于两个溶质共洗脱的等离子体停留温度的测定。该方法可以使用具有可重现性和等效结果的不同液相色谱系统进行分离。例如，该方法允许为HPLC开发的色谱方法更容易转移到UPLC系统中，并且为UPLC系统开发的色谱方法更容易转移到HPLC系统。该方法解决了具有不同设计的列炉的LC系统，其中内部柱温度不相等，尽管柱式炉的操作温度可以被精确地控制为相等的值。导致不同LC系统的保持行为和分辨率基本相同，从而获得等效的分离结果。
