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

A method for transferring a radioisotope which is fixed on a first stationary phase contained in a first chromatography column to a second stationary phase contained in a second chromatography column, to fix the radioisotope on the second stationary phase, wherein the radioisotope is selected from the radioactive isotopes of thorium, radium, lead, bismuth and uranium, the method comprising at least the following steps: a) eluting the radioisotope from the first stationary phase with an aqueous solution A1 comprising an agent complexing the radioisotope, whereby an aqueous solution A2 which comprises complexes of the radioisotope is obtained; b) dissociating the complexes of the radioisotope present in the aqueous solution A2 by modifying the pH of the aqueous solution A2, whereby an aqueous solution A3 comprising the decomplexed radioisotope is obtained; c) loading the second stationary phase with the aqueous solution A3; and d) washing at least one the second stationary phase with an aqueous solution A4.

An injector includes an injection device and a round turret provided on a front side of the injection device. A sampler is provided with a vial holder and a conveyance arm. The injector has an accessible structure in which a moving path of the conveyance arm of one sampler arranged on the side of the two injectors for accessing the round turret of each of the two injectors is secured regardless of the size of the round turret, when two injectors are arranged so that the back sides of the injection devices face to each other.

Technologies for rapid equilibration for water isotope analysis are disclosed. In at least one illustrative embodiment, a vaporizer may include an injection block that defines a chamber and a septum positioned over an inlet of the chamber to seal the chamber. The chamber may be configured to be fluidly coupled to a pump to develop a vacuum within the chamber, and the septum may be configured to receive a needle that is inserted into the chamber. A thermally conductive wool may be positioned within the chamber and may be configured to receive a tip of the needle.
