The invention relates to initial 68Ge/Ga-generator elute which is guided directly to a cation exchanger, whereon 68 Ga is quantitatively absorbed and is cleaned simultaneously in a chemical and radio chemical manner.

A method and compositions are described for labeling a targeting agent with Ga-68, in which eluate from an acid-eluted Ge-68/Ga-68 generator is combined with a macrocycle-containing targetable agent.

Said eluate, having a pH ≤ 4, is brought in contact with an acidic cation exchanger, wherein the L-cysteine bonds to the cation exchanger.

The system includes cradles for holding shielded vials containing eluate or the final kit from cold kit vials.

The kit of the invention comprises a capturing device, a detecting device, a report molecule for labeling and an analysis substance eluate.

The anion exchanger is then rinsed with a first washing solution, and the bonded L-cysteine is removed from the anion exchanger by means of an acid and transferred into an eluate.

In these cards, TAQ polymerase is stored "on-board" in vitrified dry form without lyophilization or freezing, and is reconstituted by either the sample or a sample eluate during the assay.

In particular, the chromatographic data is acquired during selective reaction monitoring of an eluate from the liquid chromatography column containing the peptide of interest.

Phosphorous ions are extracted (210) from solutions by adsorbing phosphorous ions in a scavenger and by releasing the phosphorous ions into an eluate during regeneration (230) of the scavenger.

A method for preparation of a heat-stable Factor VIII concentrate is characterised by subjecting a controlled pore glass (CPG) eluate to a diafiltration step.

The method comprises the steps of obtaining a sample of the progressively growing tumor from the tumor-bearer and eluting the sample with hypotonic salt to produce an eluate.

The ion exchange tube is folded or wound round multiple times within a plane into a sheet form and is used as an ion exchange tube sheet for flow of an eluate from the separation column.

The waste may be considered as meeting the acceptance criteria for DOC if the results of this test do not exceed 500 mg/l.

The test procedure specified in ISO/TS 21268-2:2007 produces eluates, which are subsequently characterised by existing physical, chemical and ecotoxicological standard methods.

This method also includes disrupting the red blood cells to release hemoglobin and form a hemoglobin solution, which is then treated by high performance liquid chromatography to form a hemoglobin eluate.
