Varian Introduces two OMIX SPE Formats for Bioanalytical Sample Preparation
Product News Jan 20, 2006
Varian, Inc.has introduced two OMIX® micro extraction solid phase extraction (SPE) formats for bioanalytical research that deliver improved performance and a streamlined sample preparation process.
The first is designed to enable vacuum-free SPE processing of biofluid samples directly in the tip of a popular liquid-handling device. The second is a micro-volume 96-well plate designed to process small sample volumes.
OMIX features a monolithic sorbent technology that allows for efficient extractions performed with low elution volumes, improving sample throughput and analytical quality.
The first format, OMIX micro extraction pipette tips for TOMTEC®'s Quadra instruments, eliminates the need for vacuum processing and allows TOMTEC's instruments to be used in a fully automated, walk-away capacity.
Varian claims that, for the first time SPE can be performed directly in the Quadra compatible pipette tips. This is possible only due to the bi-directional, clog-free flow properties of the OMIX monolithic media.
A second format, OMIX 96-well plates, features the same small-bed micro processing capabilities in an SBS-compatible device which interfaces with standard 96-well liquid-handling equipment used in bioanalytical research.
Analysts can reduce their elution volumes by a factor of up to 10 and still maintain equal or superior recoveries and reproducibility.
This improvement offers significant throughput gains because direct injection of the small extracts achieved with OMIX eliminates the need for additional transfer and evaporation steps.
"The expansion of our OMIX tips for pharmaceutical applications further delivers on our strategy to focus on consumable products in the high-growth life sciences area," said Stephen Schultheis, Consumable Products Vice President and General Manager, Varian, Inc.
