Analysis of drug panels in urine samples can be challenging, and the trend towards larger panels including multiple drug classes compounds the issues faced during method development.
This white paper examines a number of aspects of sample preparation, and their impact on the success of subsequent LC-MS/MS analysis of broad urine panels.
Section 1 examines the applicability of various sample preparation techniques: supported liquid extraction, reverse phase SPE and mixed-mode SPE, to the various classes of drugs extracted. In addition, hydrolysis approaches: enzyme type and protocol used (time, temperature), are compared.
Mixed-mode reverse phase/cation exchange SPE is widely used for extraction of basic drug classes from urine, but the inclusion of drugs and metabolites that exhibit ‘non-typical’ functionality within urine panels can be problematic. Section 2 examines the impact of various parameters (interference wash strength, elution solvent composition) on analyte retention, elution and extract cleanliness with particular focus on zwitterionic (gabapentin, pregabalin) and non-ionic (carisoprodol, meprobamate) drugs.

Designed polymers are a class of selective resins with engineered selectivities for particular target molecules or ‘classes’ of molecules. These designed polymers are obtained by careful tuning of their surface chemistry and morphology which allows them to exhibit unique separation capabilities. The tailored and optimized selectivity of designed polymers is utilized to conduct difficult separations that are not able to be accomplished with conventional separation resins or other techniques.

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.

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

This poster demonstrates the extraction of a range of drugs of abuse from oral fluid, collected with common collection devices, prior to UPLC-MS/MS analysis. The target analyte list includes benzodiazepines, z drugs, amphetamines, cathinones, opiates, cocaine, buprenorphine, PCP, THC-COOH, fentanyl and ketamine.

This poster demonstrates the extraction of a range of drugs of abuse from oral fluid collection devices using supported liquid extraction suitable for UPLC-MS/MS analysis. Unlike some sample preparation techniques, SLE allows for the simultaneous extraction of cross-functional analytes in a single extraction protocol without forfeiting extract cleanliness.
The target analyte list includes benzodiazepines, z drugs, amphetamines, cathinones, opiates, cocaine, buprenorphine, PCP, THC-COOH, fentanyl and ketamine.

Matrix components, particularly salts, proteins and
phospholipids, can lead to ion suppression resulting in
inaccurate quantitation and reduced detection limits.
Resin-based mixed-mode cation exchange SPE sorbents
are widely used for the extraction of basic compounds
from biological fluids. The dual retention mechanism
allows a two stage interference wash protocol, which
results in extremely clean extracts.
This poster will investigate the performance of
EVOLUTE™ CX for the extraction of a wide range of basic
drugs from plasma, showing high analyte recovery and
advanced extract cleanliness. The analyte suite was
selected to cover a variety of basic analytes with wide
ranging polarities (LogP values). Extract cleanliness
experiments were performed showing overall ion
suppression, then individual matrix components examined
in terms of protein and phospholipid removal.

This poster evaluates the extraction of a range of drugs of abuse from hydrolyzed and nonhydrolyzed urine using a novel flow through scavenging product, ISOLUTE® HYDRO DME+. Matrix component removal in terms of creatinine and urea, salt residue, pigmentation associated with urobillin content and protein removal will be demonstrated.

Methylisothiazolinone (MI) is used in a variety of personal care products, such as sunscreens, lotions, cosmetics. MI is a cytotoxin and as a result there is concern because of sensitization and allergic reactions as well as cell and nerve damage. A percentage of the population is at risk from contact dermatitis when exposed to this compound at sufficient concentrations. This poster describes the use of ISOLUTE SLE+ for extraction of MI from sunscreen.
