In order to concentrate to 1.0 mL of solvent, the TurboVap must be configured such that the sensor is mounted with spacers on the bottom plate of the internal rack (Figure 1). To concentrate to 0.5 mL of solvent, the TurboVap must be configured such that the sensor is flush to the bottom plate of the internal rack (Figure 3). If the TurboVap is not correctly configured, the light beam from the sensor will not be aligned with the desired endpoint of the tube.

In determining the gas flow rate, the goal is to achieve
the maximum evaporation rate possible without
splashing or compromising the sample. During
evaporation the distance between the nozzle tips
and the liquid surface increases, therefore, the flow
rate may be safely increased as the evaporation
progresses to shorten evaporation time, if so desired.

US EPA method 625 is used to determine acidic, basic, and neutral semi-volatile organic compounds (SVOC) in municipal and industrial wastewater. Revision A of this method is applied to a total possible list of 364 compounds that include; polynuclear aromatic hydrocarbons, chlorinated hydrocarbons, pesticides, phthalate esters, organophosphate esters, nitrosamines, haloethers, aldehydes, ethers, ketones, anilines, pyridines, quinolones, aromatic nitro compounds, and phenols.

This application note describes a protocol for the extraction of 1,25 di-OH Vitamin D2 and 1,25 di-OH Vitamin D3 metabolites from serum using supported liquid extraction prior to LC-MS/MS detection.
A calibration range between 5 and 500 pg/mL is demonstrated using a starting volume of 0.25 mL of serum. Sensitivity is maximized through the use of a simple PTAD derivatization and formation of a methylamine complex.
The method can be easily automated using the Biotage Extrahera. Details of the automated procedure and data comparing manual and automated method performance are included.

Free urinary cortisol levels can be an indicator of a variety of disorders, such as Cushing Syndrome. This poster presents a simple method for the extraction of cortisol from urine demonstrating good recoveries and low ion suppression. LC-MS/MS analysis was performed using a Waters 2795 Liquid Handling Unit coupled to a Quattro Ultima Pt triple quadrupole MS using electrospray ionization, operated in the MRM mode. Supported liquid extraction method development resulted in recoveries greater than 90% for cortisol spiked urine. Calibration curves constructed using this method from 25-2000 ng/mL, demonstrated excellent linearity with coefficients of determination greater than 0.99.
