Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.

Now there's an single-purpose HPLC with a simplified UI that makes it possible for anyone to perform HPLC testing with a sinple one-button pass/fail test function.

The solution is an automated reaction monitoring system capable of unattended sampling, identification, and quantification of reaction components via HPLC. Axcend system is the only separations Process Analytical Technology (PAT) system that’s small enough to be placed in a hood or immediately adjacent to the reaction vessel.

A recent study examines the specific traits of the intestinal microbiota and metabolites in Bactrian camels. The results of profiling 36 intestinal mucosal samples from six Bactrian camels using liquid chromatography with tandem mass spectrometry (LC-MS/MS) provides valuable data for understanding the relationship between regional intestinal immunity and the general health and disease of the host.
