SOLAμ for Pre-Analysis Sample Concentration

18 Sept 2014

This application note demonstrates the use of Thermo Scientific™ SOLAμ™ SPE product to enhance sample pre-concentration prior to analysis. Additional benefits include reduced workflow and stability for analytes susceptible to loss or degradation during evaporation and reconstitution. The use of a Thermo Scientific™ Accucore™ HPLC column provided fast and efficient separation without the need for an ultra high pressure system. MS/MS detection was performed on a Thermo Scientific™ TSQ Vantage™ mass spectrometer.

Thermo Scientific™ SOLAµ™ Solid Phase Extraction 96 Well Plates

Thermo Fisher Scientific

Remove variability and optimize high throughput laboratory workflows. Thermo Scientific™ SOLAµ™Solid Phase Extraction (SPE) Well Plates are designed for bioanalytical and clinical research analysts who require cleaner, highly reproducible, and robust sample extraction using very low sample and solvent volumes in high throughput workflows. SOLAµ Well Plates achieve this due to the unique and award winning innovative frit-less SPE technology.Bioanalytical laboratories continue to drive to higher efficacy drugs and long acting formulations which require lower quantification limits. There is also the desire to take advantage of the replacement, refinement and reduction policy which is resulting in reduced animal model use. The growth of biopharmaceuticals also brings into consideration additional analytical issues such as solvation and non-specific binding.Features & Benefits: Processing of low sample volumes High sensitivity due to low elution volumes High reproducibility Low analytical sample failures Ease of use High throughput processing

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats. Find the best SPE, SLE and SPME equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Sample HandlingProper and careful handling of samples is important in scientific studies to ensure the integrity of specimens. This will prevent deterioration and cross contamination, and improve the accuracy of sample tracking procedures.Solid Phase Extraction (SPE)Solid phase extraction (SPE) is a sample preparation technique used to separate and concentrate analytes from complex mixtures. It is widely used in environmental, pharmaceutical, and clinical analysis. SPE provides higher sensitivity and selectivity compared to traditional liquid-liquid extraction methods, making it essential for accurate and reproducible results.
