Article Synopsis
- Ultrasound is a non-invasive technique that has limitations in providing chemical information but can estimate pH in albumin-rich fluids by analyzing ultrasound frequencies.
- Changes in pH affect the attenuation of ultrasound signals in albumin solutions, allowing for pH measurement through multilinear regression of frequency spectra.
- A robust model was developed from human serum samples, achieving high accuracy (R² = 0.93), and this method can potentially be applied to other albumin-rich biological fluids.
Great variations in pollutant concentrations are observed in the environment and pre-concentration is often required to detect trace contaminants in water samples. This paper presents a novel solid phase-extraction device integrated onto a centrifugal microfluidic platform for rapid on-site pre-concentration and screening of organic contaminants in aqueous samples. In-column fluorescence and absorbance measurements are obtained directly from an analyte trapped on the top of a solid phase extraction microcolumn.
