This poster demonstrates that a large urine panel, comprised of 43 DOAs, from multiple drug classes, can be simultaneously screened by mixed-mode cation exchange SPE (using EVOLUTE EXPRESS CX 96 well plates) despite their disparate intermolecular traits, by thoughtfully selecting appropriate organic wash and elution conditions that simultaneously enable sample isolation and detection along with minimizing sample matrix effects.
The extraction method is automated using the Biotage® Extrahera™ Automated sample Preparation Platform.

One of the most common flash purification challenges is
dealing with hard-to-dissolve crude samples. Because polar
solvents cause poor chromatographic results when used as
injection solvents in normal-phase flash chromatography, other
sample load options are needed.

Removing water with a membrane rather than the older technique of passing the solvent through a column of sodium sulfate (Na2SO4) brings several advantages. The most important analytically is that the membrane will not adsorb analytes or contaminate the extract with matrix or other potential interferences.

Why spend hours using traditional evaporation techniques when the automated evaporation capability of the DryVap System can take your compound to
dryness in minutes? Through the precise application of vacuum, heat and nitrogen sparge, the DryVap System gently and predictably evaporates all residual solvent from your compound allowing you to quickly move on to the next step.

With the de-criminalization of recreational cannabis, containing the hallucinogen THC, and other cannabinoids with purported medicinal value, e.g. CBD (Figure 1), in several states a need for higher purity “products” has become a necessity. Current technology uses extraction with supercritical fluids or other non-supercritical solvents to remove the products of interest from other endogenous species such as lipids, terpenes, and chlorophylls as well as pesticides.
These techniques help clean up raw extracts and isolate cannabinoids with higher-purity but not to the levels desired by many producers so there is a developing need for a secondary purification step.

Buprenorphine and Norbuprenorphine are typically problematic for analysis due to analyte stability issues during sample preparation.
This poster will demonstrate two fast and robust methods for the extraction of buprenorphine and norbuprenorphine in urine (using EVOLUTE EXPRESS CX), oral fluid (using EVOLUTE EXPRESS CX) and whole blood (using ISOLUTE SLE+).

Endogenous phospholipids present in biological fluids are a major problem in LCMS/ MS analysis as they are often very difficult to remove during sample preparation. When phospholipids are not removed, they retain very strongly on reversed phase analytical columns. If high organic (end of run) washes are not incorporated into the LC methods these matrix components may elute in subsequent analyses causing regions of suppression/enhancement leading to inaccurate quantitation. This poster evaluates the use of polymer-based solid phase extraction (SPE) sorbents, incorporating hydrophobic and various mixedmode retention mechanisms to address the problems associated with phospholipid removal.

Endogenous phospholipids (outline structure shown in
Figure 1.) present in biological fluids are a major problem
in LC-MS/MS analysis. Due to their strong retention
characteristics in reversed phase chromatography
phospholipids tend not to elute as discrete peaks and are
often very difficult to separate from analytes of interest.
This co-elution often leads to areas of suppression or enhancement in the chromatogram which in turn can cause
quantitation issues. Supported liquid extraction (SLE) is an
analogous technique to traditional liquidliquid
extraction. This poster compares phospholipid removal using a wide variety of solvent combinations, pH control and polar extraction solvents on supported liquid extraction plates

Method 1668A is used for determining the level of chlorinated biphenyl congeners by high resolution gas chromatography with high resolution mass spectrometry (HRGC/HRMS). For aqueous samples (samples containing less than 1% solids) – Stable isotopically labelled analogs of the toxic PCB’s are spiked into a 1L sample, and the sample is extracted using the Biotage® Horizon 4790 Automated Extraction System along with the Atlantic™ C18 solid phase extraction (SPE) disk.
Samples are then dried and concentrated using the DryVap® Automated Drying and Concentrating System with DryDisk® technology.
