The TurboVap® 96 is a high speed concentrator designed to work with 96-well microplates and deep-well plates. It is an efficient alternative to the constant monitoring and long evaporation times that are characteristic of conventional techniques — with the added bonus of unattended operation.

In order to decide which model TurboVap will best fit a laboratory’s application, the following questions should be asked, along with following the flowchart on the reverse side:
• After extraction on the Dionex ASE, what is the matrix of my extract?
• After extraction on the Dionex ASE, will the extract require further cleanups or drying steps?
• What other types of samples may require concentration that are not extracted on the ASE, so that I may select the model TurboVap that will be suitable for all types?
• Do I have enough Dionex ASE extracts and enough non-ASE extracts to justify two separate model TurboVaps?
• Does it make sense for me to purchase a standard TurboVap model now, and convert with the ASE compatible kit later?

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.

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.

Acetone is successfully used as solvent in normal-phase flash chromatography when used with an Isolera™ Spektra flash purification system. The new λ-All detection and baseline correction features provide compound detection at all wavelengths in the detector’s range while minimizing any baseline drift due to solvent UV absorption.

With the growing popularity and use of mass-directed flash
chromatography to purify specific compounds, it is important to understand that the sample’s compounds may not be detected as expected (e.g. M+H or M-H ions) because they may fragment or form adducts in the mass detector. This is true with both synthetic and natural product research.

The use of reversed-phase high performance flash chromatography
(HPFC) is gaining traction as a strategy to reduce the
overall purification time for synthetic peptides. Herein we
present data demonstrating that a focused gradient, with a
slope reminiscent to that commonly used for HPLC-mediated
peptide purification, can indeed be used in HPFC to improve the
final purity of a desired peptide with minimal time invested in
