One of the basic determinations in the pharmaceutical field is the determination of bacterial endotoxins (LAL tests). This determination determines the amount of pyrogenic substances in the sample. Pyrogenic substances are all substances that can cause an increased body temperature in a patient after ingestion or administration of a medicament. Testing of final products is inadequate and it is necessary to monitor the occurrence of pyrogenic substances during the whole production process.... Read more »

The new acquired TESCAN VEGA 3 scanning electron microscope (SEM) coupled with an energy dispersive spectrometer (EDS) allows identification of fibers and determination of the number of asbestos fibers in the air – (see news from 10. January 2019), and moreover its configuration is also suitable for observing and analyzing the structure of material surfaces.
Using the EDS detector, it is possible to determine semi-quantitative elemental composition of the observed sample or particle. As... Read more »
