Embodiment Construction

[0060] Before describing the figures in more detail, some basic considerations of the invention, on the basis of which the exemplary embodiments have been developed, will be summarized.

[0061] The separation result (chromatogram in the case of chromatography) is defined by a combination of the properties of the fluid sample to be separated, the separation method performed (in particular chromatographic method) and the device characteristics of the sample separation device (in particular chromatographic device). A part of the sample separation device is an injector which has the function of aspirating a fluid sample from a sample container and then injecting the aspirated fluid sample into a separation path of the sample separation device. Each injector has its own influence on the separation result.

[0062] According to an exemplary embodiment of the invention, an injector of a sample separation device is configured via an input interface by providing a data set defining in...

Abstract

A configurable injector (40) for injecting a fluidic sample in a separation path (102) of a sample separation apparatus (10), wherein the configurable injector (40) comprises a sample accommodation volume (100) for accommodating the fluidic sample to be injected into the separation path (102), a valve arrangement (104) fluidically couplable with the separation path (102), fluidically coupled with the sample accommodation volume (100), and being controllable for injecting the fluidic sample into the separation path (102), an input interface (106) configured for receiving input data indicative of an injection profile of an injector to be emulated (108) by the configurable injector (40), and a control unit (70) configured for controlling the configurable injector (40), in particular the valve arrangement (104), so that the configurable injector (40) is operated in accordance with the injection profile to thereby emulate the injector to be emulated (108).

Description

technical field [0001] The invention relates to an injector, a sample separation device, a method for injecting a fluid sample in a separation path of a sample separation device, a program element and a computer-readable medium. Background technique [0002] In liquid chromatography, a fluid sample and an eluent (liquid mobile phase) can be pumped through tubing and a separation unit, such as a column, in which the sample components are separated. Columns may comprise materials capable of separating different components of a fluid sample. The separation unit can be connected to other fluid components (eg samplers or injectors, detectors) via tubing. Before introducing the fluid sample into the separation path between the fluid drive unit (in particular a high-pressure pump) and the separation unit, a predetermined amount of the fluid sample should be injected via the injection needle from the sample source (such as sample container, etc.) into the sample loop. This usuall...
