Aseptic Identification of Polysorbates using Handheld Raman
Application Note

As polysorbates are reactive to light and air, packaging is usually in thick, dark, amber bottles. This makes the identification process more difficult, as opening the container could compromise the sterility and quality of these materials. Handheld Raman is capable of identifying these materials without any sampling or preparation.

Simple sample preparation for the determination of vitamin D in serum by LC-MSMS
Application Note

Tecan Group Ltd.

A growing number of laboratories have moved from the use of immunoassay methods to liquid chromatography coupled with tandem mass spectrometry (LC-MSMS) for the determination of vitamin D. The advantage of the latter method is unparalleled specificity combined with high sensitivity, offering the potential for the determination of multiple analytes, such as 25OH-vitamin D3 and 25OH-vitamin D2.
