Endogenous steroid hormone extraction from serum, and catecholamine extraction from plasma and urine.

About Biotage

MRM transitions, chromatography and mobile phase additives for use with positive and negative ionisation modes. This poster compares sample preparation options for the extraction of a panel of endogenous steroids from serum.

This application note demonstrates that the Biotage R Horizon using Atlantic C18 disks can effectively extract hormone compounds from 1-L water samples in approx 40 mins. Naaproxen phase extraction was compared to curfe liquid extraction in terms of recoveries, ion suppression, phospholipid content, calibration curve performance and overall sensitivity.

Modern mass spectrometers are extremely sensitive allowing low level detection of many target analytes. This compendium highlights a selection of clinical sample preparation applications from Biotage. However, this sensitivity can come at a price, in that levels of contamination not previously detected with less sensitive instruments can now have larger impact on analysis.

Biotage – Search Literature

As a result sample preparation is an extremely important part of the process in order to provide robust methods. Particular emphasis is placed on the various sample preparation options we looked at for the extraction of these analytes.

Title Document number Year File type File size. Whether you need targeted methods for analytes such as Vitamin D metabolites in serum, or methods suitable for extraction of a wide panel of drugs and metabolites from urine, sample preparation before analysis is essential.

Clinical Applications Compendium Part No: P rev 2 Issued year: During optimization of the extraction process we investigated analyte recovery, co-extractable matrix components, HPLC column degradation, calibration curve performance and limits of quantitation. Particular emphasis was placed on the sample preparation to provide high reproducible recoveries whilst minimizing matrix effects and co-extracted materials such as proteins and phospholipids.

Year This seminar focuses on some of the method development challenges our lab faced when looking at two clinical assays:
