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.

As a result, detection using oral fluid devices for Drugs of Abuse (DOA) has come to the vanguard of the scientific community. The use of Supported Liquid Extraction (ISOLUTE® SLE+) prior to LC/MS or GC/MS can improve sample cleanliness without forfeiting sample detection within a diverse panel of DOAs. Here, we demonstrate the effects of altering elution solvent polarity and pH for sample pretreatment upon the simultaneous recovery of 34 compounds comprised of opioids, benzodiazepines, and stimulants to directly measure the effects of the oral fluid buffer, OraSure™, upon extraction and signal intensity at presumed LOQs.

Immunosuppressant drugs are instrumental in preventing organ and tissue rejection in patients undergoing transplant surgery. Mycophenolic Acid is a common immunosuppressant drug used in patient transplant therapy. The ability to monitor the trough levels in patients to evaluate dosing is important for the administering of the drug. The free drug and its glucuronidated metabolite can be found in patient serum. The ability to extract the free drug and metabolite in patient serum is supported by using a fast and efficient sample preparation extraction method called Supported Liquid Extraction (ISOLUTE SLE+). The free drug and metabolite can be recovered from serum using ISOLUTE SLE+ with high enough efficiency to allow for quantitation at target trough levels. MSACL 2014

Drug of abuse testing is typically conducted using urine specimens from patients being screened for illicit drug use. While collection of urine is considered a relatively non-invasive drug testing action, it is not convenient for law enforcement to do in the field. The ability to collect an oral fluid sample in the field can be considered non-evasive and simple to implement. Currently there are oral fluid collection kits (e.g. Immunalysis Quantisal™, Orasure Technologies Intercept®) that facilitate the collection in easy to follow protocols. Oral fluid samples collected using standard collection kits can be qualitatively and quantitatively analyzed by LC-MS/MS, post extraction of the target analytes from the matrix. Drug analytes can be successfully extracted from oral fluid using Supported Liquid Extraction (ISOLUTE SLE+), which offers an efficient alternative to traditional liquid-liquid extraction (LLE). In this poster, we demonstrate a new rapid and reliable sample preparation method to extract a broad suite of drugs (Figure 1) from neat oral fluid and buffered oral fluid matrices. MSACL 2014

Testing for drugs of abuse in oral fluids can strongly benefit the criminal justice field as a less invasive and cost-effective approach for drug detection when compared to blood or urine sampling. Oral fluid analysis has facilitated laboratory analysis for many drugs of abuse and is a constantly evolving analysis procedure which benefits from increasingly sensitive methods of detection. The Laser Diode Thermal Desorption (LDTD) source combined with Mass spectrometry is presented as a new screening tool for drug analysis in Oral Fluids. Analysis speed of LDTD provides accurate results in seconds in combination with exceptional specificity of MS instruments make a powerful platform for the screening of different drugs of abuse and new emerging drugs. Different extraction procedures are available; however those methods depend on specific drug conditions: basic or acid drugs / hydrophilic or hydrophobic. A new extraction approach, Supported Liquid Extraction (SLE+) is evaluated as generic extraction procedure. MSACL 2014

Pain management therapy warrants constant monitoring of therapeutic levels of prescribed drug levels in patient urine samples. The number of samples being submitted for analysis has increased dramatically in the last 10 years with improvements in high throughput automated screening capabilities. Patient samples analysis is complicated by the need for an effective sample preparation methodology that can extract target analytes from complex matrices with good efficiency. Further complicating the process is the need to enzymatically hydrolyse the glucoronidated metabolites prior to extraction from the urine matrix. A fully automated sample preparation process using a TECAN Freedom EVO® 100 was designed to incorporate both the enzymatic hydrolysis and subsequent sample preparation assay as one continuous workflow. Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) and solid phase extraction (SPE) techniques was used to extract a suite of pain management drugs from spiked urine samples. A recovery and quantitation assay was run on the TECAN Freedom EVO® 100 using mock patient samples to demonstrate utility of automation process.

The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in patient urine samples. Screening patient urine samples is further complicated by the metabolic process which converts the free drug to the - glucuronide form. The target drugs in patient urine samples can be enzymatically hydrolysed and extracted using Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) and solid phase extraction (SPE) techniques typically used for this type of clinical sample preparation.

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 ASMS 2011

It is well known that traditional liquid-liquid extraction (LLE) provides very clean extracts prior to LC/MS analysis. Supported liquid extraction is analogous to traditional LLE, however, analyte partitioning takes place using an inert support material, rather than two immiscible liquids. This provides excellent extraction efficiencies while alleviating many of the tedious liquid handling issues associated with LLE.
