Deadline for product authorization of ADBAC and DDAC PT 3 and 4

The deadline for applying for product authorization for the active substances ADBAC/BKC (C12-C16) and DDAC in biocidal products of PT 3 and 4 is 01 November 2022. Good to know that LAUS has already experience with the analytical determination of quaternary ammonium compounds like DDAC.

LAUS setzt ein Ausrufezeichen beim Fechtsport!

Im Zeichen der Corona-Krise sind besonders Hallensportarten von den Restriktionen betroffen. So sinnvoll hohe Sicherheitsmaßnahmen auch sind, so aufwändig ist es für Vereine, Wettkämpfe zu organisieren. Anlass für LAUS, auszuhelfen und zu unterstützen! Dietmar Kuhn von LAUS war es wichtig zu zeigen, dass zurzeit mit hohen Auflagen Sport in Rheinland-Pfalz möglich ist. – Mit Hilfe von LAUS konnten sich am 04./05.12.2021 in Mainz nicht nur Rheinland-Pfälzer, sondern Fechter aus fast dem gesamten Bundesgebiet zwischen Lütjensee und München zum Winter-Cup in Mainz versammeln. Der Winter-Cup in Mainz ist Teil einer Turnierserie, die von den Leistungszentren Nürnberg, Eislingen, Mainz und Künzelsau organisiert wird. Säbler*Innen in den Klassen U9 bis U17 konnten sich in ihren Altersklassen messen und so die Besten ausmachen. Zeigten sich die Gäste aus den anderen Bundesländern anfänglich verwundert, ob der klaren 2G+ Regeln, so überwog am Ende die Freude, dass Hallensport trotz Corona möglich ist. Angesichts der großen Begeisterung und dem allgemein hohen Niveau waren die Ergebnisse schon nahezu nebensächlich. Dennoch möchte LAUS den Rheinland-Pfälzischen Siegern aus Kaiserlautern (Silantyev/Aktive) und Mainz (Barth/U9, Larres/U17, Graudins/U17+Aktive) herzlichst gratulieren.

Characterization of Nanoparticles

Did you know that there are two direct techniques of characterizing nanoparticles <100 nm?

You need a multitude of analytical tools to describe a nanomaterial sufficiently:

FTIR with ATR / XRF or ICP-MS / XRD incl. Rietveld analysis / BET / Zeta Potential / DLS / PSD / EDX…


But transmission electron microscopy (TEM) and scanning electron microscopy (SEM) are the only direct methods to analyze particles below 100 nm in diameter (in at least one dimension) and to describe primary particles in size and form as well as their agglomeration state appropriately.
