Analytical chemical technician GeoLab for water analysis

Descrizione

Testo originale dell'annuncio (in inglese)

The GeoLab is the central laboratory of the Faculty of Geosciences, where highly diverse research into the system Earth is conducted, often by using advanced analytical instruments. As analytical chemical technician for water analysis, you strengthen our team by analyzing the chemical composition of various types of water samples. Your job The GeoLab is divided into several lab units, each with its own expertise. In the water lab, you analyze the chemical composition of various types of water samples like, for example, freshwater, seawater and porewater. For the analysis, you make use of an ion chromatograph, a discrete analyzer for the spectrophotometric determination of, for example, macronutrients and a DOC analyzer for the measurement of dissolved carbon compounds. You conduct analyses for our students, scientists and sometimes external customers and report the processed results. You are responsible for the proper functioning of the equipment and the quality control of the measurements. Research is constantly evolving and requires new or adapted methods. With your knowledge of the chemistry of complex solutions (i.e. seawater and porewater matrices), you will develop methods in cooperation with research faculty for the available analytical instruments that meet the need of the researchers better, and are preferably also more sustainable. Additionally, you advise lab users (e.g., students) on sample collection and pretreatment where necessary. You work primarily in the water lab, where you will be supported by colleagues from the experimental lab. Vice versa, we expect you to be able to support your colleagues there as well when necessary. In the experimental lab, very diverse research is conducted on geological materials and environmental samples. Some examples of these experiments include reactions of organic compounds under conditions comparable to those on Mars and the release of phosphate from sediments under different circumstances. Within the experimental lab, we have a microbiology lab, cleanrooms and climate chambers available. Your contribution here will be primarily facilitative. Preferably, you are already familiar with Emergency Response (in Dutch BHV) or are willing to become an Emergency Responder to strengthen our BHV team in the lab. Your tasks include: You analyze the chemical composition of water samples using the analytical instruments available and report the processed data; You are responsible for the quality control of the measurements and the proper functioning of the instruments. This includes the preparation and use of standards and reagents. You can conduct daily maintenance independently; You develop new or modified methods together with researchers and can advise them about sample collection and pretreatment where necessary; You work closely together with your colleagues by supporting each other; You support fieldwork and lab courses and their preparation; Preferably, you are willing to act as an Emergency Responder in the event of an emergency.
