How developments in the automotive industry can predict the future of chromatography applications
Dr. Moritz Kneipp, Sensirion AG
Early iterations of chromatography systems required their operators - typically a highly trained scientist in a high-tech research facility - to manually prepare each sample for the next experiment. While an analytical procedure or process can be as short as minutes or even seconds, typical sampl...

Optimization of the stabilization process of aqueous TiO2-pigment dispersions for dip coating applications by means of electrokinetic sonic amplitude
Daniel Moog, Pulveranalyse GbR
The high-quality white pigment titanium dioxide has many applications. Coagulation or agglomeration of a TiO2 dispersion must be avoided at all costs, both in the manufacturing process and in the processing, e.g. by manufacturers of paints and coatings. This applies in particular to highly filled...

The 60th birthday of a pipetting masterstroke
Eppendorf SE
2021 marks a key milestone for anyone working in a lab. Sixty years ago, Eppendorf changed the ways of handling liquids forever by introducing the world's first industrially manufactured piston-stroke pipette. Launched in 1961, the Eppendorf 'Marburg Pipette' featured the same basic elements as t...

MSn analysis of nonderivatized and Mtpp-derivatized peptides
Dr. Dorota Gaszczyk, Prof. Zbigniew Szewczuk, Dr. Alicja Kluczyk, University of Wroclaw
The LC-MS-IT-TOF combines QIT (Ion Trap) and TOF (Time-Of-Flight) technologies. The QIT ion trap gives an efficient MSn capability. After selecting the appropriate precursor ions, several MSn experiments could be performed during one introduction of the sample, with product ions obtained serving ...

What Exactly Is a Pollen Allergy?
Kristen Stewart, Zyrtec
Many people welcome spring with its warmer weather, longer days, and blossoming flowers and trees. For the more than 26 million Americans who suffer from allergic rhinitis including pollen allergies, however, this season can be full of misery. What Is Pollen? Pollen is a very fine powdery substa....

New derivatization reaction of perfluorcarboxylic acids with N,N-dimethylformamide dialkylacetals
Dr. Katrin Schuhen, Wasser 3.0
Monika Breithaupt, SAS Hagmann GmbH
N,N-dimethylformamide dialkylacetals are very powerful derivatization reagents. The most known member of this group is N,N-dimethylformamide dimethylacetal or shortly DMF-DMA. We tried to use this compound to derivatize perfluorooctanoic acid (PFOA) and form an ester. However, our research showed...
