Identify and quantify different plastic compositions in the recycling stream
Dr. Omeir Khalid, Dr. Natalie Rudolph, NETZSCH Gerätebau GmbH
Plastics are part of our daily life in various ways. While technical parts are typically used for many years, the vast majority of packaging items are only used for days or weeks. At the same time, packaging applications make up around 50 % of the plastic production. Since plastics have a poor bi...

Supercritical Fluid Chromatography coupled to an Orbitrap Exploris 120 mass spectrometer - Quantitative Viewpoint
Stefan Bieber, Dr. Thomas Letzel, Analytisches Forschungsinstitut für Non-Target Screening GmbH
Achiral supercritical fluid chromatography (SFC) was investigated on its capability to separate molecules in a huge range of polarity. It mostly represents a so-called polarity-extended chromatographic separation technique. A highly accurate and high resolution Orbitrap Exploris 120 mass spectrom...

Electrospray Ionization Efficiency Predictions and Analytical Standard Free Quantification for SFC/ESI/HRMS
Stefan Bieber, Dr. Thomas Letzel, Analytisches Forschungsinstitut für Non-Target Screening GmbH
Anneli Kruve, Stockholm University
Supercritical fluid chromatography (SFC) is a promising, sustainable, and complementary alternative to liquid chromatography (LC) and has often been coupled with high resolution mass spectrometry (HRMS) for nontarget screening (NTS). Recent developments in predicting the ionization efficiency for...

Thermal analysis: Quality differences in commercial charcoal
Dr. Carolin Fischer, NETZSCH Gerätebau GmbH
Summertime is barbecue time. But have you ever wondered which charcoal is best to use? The quality of charcoal can be characterized by the amount containing organic compounds, the ash content and energy released during combustion. These are all properties which can be determined using the simulta...

Strawberries - Ingredients in focus - Universal tool capillary electrophoresis
Jana Boden, Antje Mainka, Ingo Haumann, ICA - Ingenieurgemeinschaft für Chemische Analytik
The most delicious symbol of early summer invites us to enjoy and feast - the strawberry. The first plants of strawberries came to us from America in the beginning of the 18th century. Due to different breeds, we now have many popular types like "Mieze Schindler" or "Senga Sengana" [1]. The g...

New hopes to treat sepsis and metastases: A drug based on metformin binds copper
Sebastian Müller, Institut Curie
How can cells of the human body respond quickly to physical and chemical changes in their environment? Although genetic mutations can cause changes to the properties of a cell, non-genetic mechanisms can drive rapid adaptation, in a process broadly termed cell plasticity. Cell plasticity is invol...

New technology for the development of molecular markers
Dr. Georg Johnen, Prof. Thomas Brüning, Institut für Prävention und Arbeitsmedizin der DGUV Institut der Ruhr-Universität Bochum (IPA)
The detection of specific proteins is the focus of many methods for the diagnosis of occupational diseases. The widely used ELISA is a reliable and precise method for protein detection, but it can be very time-consuming. A novel method is now being evaluated at the IPA that can significantly spee...

Isolation and enrichment of Golgi Bodies from rice seedlings
Kazusato Oikawa, Eppendorf Lab for Biomaterial Chemistry, Kyoto
Shuichi Kani, Eppendorf Himac Technologies, Tokyo
Mark Hünken, Eppendorf SE
The Golgi apparatus of eukaryotic cells was first described more than 120 years ago by Camillo Golgi. Advances in (electron) microscopy revealed the complex structure while further biochemical analysis enlighted various functions of this organelle within the cell [1]. In cells of higher organisms...

Quantitative UV/VIS-spectroscopy on turbid samples
Dr. Bernd Neumann
To obtain correct results in quantitative UV/VS-spectroscopic analyses, clear samples are crucial. In case of the spectroscopic determination of formaldehyde in water-based dispersion paints according to the VdL-RL 03 [1], this prerequisite is not always fulfilled. Certainly, a dispersion paint c...
