Sample clean-up is performed in the same plate, without the need to transfer samples, saving time and reducing risky sample handling steps. This method provides high analyte recovery, reduced extraction time due to the elimination of a sample transfer step as well as the elimination of the column conditioning and equilibration steps, and a reduced risk for sample carryover or cross-contamination due to the elimination of the sample transfer step.
In this catalog product information is displayed with easy-to-follow application details and supporting documentation. Ordering information is found following each product listing. Whether you are working in the field of bio-analysis during drug development, clinical or forensic toxicology, or with the diversity of samples in food safety and environmental applications, the tools and methods used Sa tjanar karolina pengar pa sin blogg sample preparation have a clear impact on productivity.
This poster presents a method for detection of approximately drugs and metabolites in urine using mixed-mode polymeric cation exchange solid phase extraction SPE. Four different glucuronidase enzymes and several incubation times and temperatures were evaluated to determine optimum hydrolysis conditions for seven commonly detected glucuronide metabolites.
Each approach is assessed in terms of suitability for extraction of analytes with different different properties pka, LogP etc.
Most drugs, both licit and illicit, are excreted in urine as glucuronide conjugates. Hydrolysis using red abalone, abalone, and recombinant beta-glucuronidase enzymes was evaluated using an in-well hydrolysis plate to determine which provided the most efficient hydrolysis of glucuronide metabolites without affecting overall recovery of nonconjugated compounds.
A glucuronide control containing 8 glucuronide compounds was used to determine the extent of hydrolysis that occurred. A non-conjugated control containing 96 licit and illicit drugs of abuse was evaluated to determine if signal suppression occurred as a result of enzyme hydrolysis.
This poster investigates the selectivity of polymer-based solid phase extraction sorbents and rapid extraction of clinical matrices, matrix interference reduction and improved analyte detection. This poster focuses on the different strategies that can be employed when using EVOLUTE SPE sorbents with both single and dual retention mechanisms to reduce or eliminate residual phospholipids in sample extracts.
This poster uses gel electrophoresis data to visually illustrate the amount of residual protein in extracts prepared using protein precipitation, supported liquid extraction and various silica and polymer based SPE approaches. This poster outlines a new method for the extraction of a mixture of peptides from plasma using resin based SPE. at EBF Plasma renin activity PRA determination is used in the diagnosis of primary aldosteronism, an important cause of secondary hypertension high blood pressure.

We have no indications that the performance of non-bonded phase SPE sorbents is affected by long term storage, under recommended conditions. We have no indications that the performance of bonded phase SPE sorbents is affected by long term storage, under recommended conditions. Streamlined Sample Processing The plates contain the Hydro frit technology system, which reliably holds up sample and hydrolysis enzyme during incubation at elevated temperatures, and reduces clogging during subsequent clean up steps.
