Abstract
SPE and LC
are techniques used in analysis of chemical substances that involve a
stationary phase and mobile phase. The most commonly used and universally
accepted stationary phases are based on porous silica particles. Silica based
stationary phases have the benefit of good mechanical strength, high surface
area, and strong absorption. However, they suffer from several shortcomings,
including limited pH stability, low maximum operating temperature, and wide
selectivity variation. FIU
scientists have developed a new class of
SPE sorbents and LC stationary phases using microcrystalline cellulose
particles as the substrate and sol-gel sorbent coating technology as the
polymer/sorbent immobilization technology. This invention
allows higher temperatures to be used, which is important to reduce analysis
time, enhance column efficiency, and improve detection sensitivity.
Additionally, the stationary phase support will not dissolve at high or low pH
values or temperatures.
Benefit
Reduction of analysis time in chromatography Enhancement of column efficiency when performing column chromatographyImprovement of detection sensitivityHigh thermal stability (up to 350 °C)High pH stability (1-13)
Market Application
Identification of components of substances in forensicsQuality assurance in the food industryIdentification and separation of contaminants
