Excellent Optical Performance
Quartz flow cells are typically constructed from fused silica tubing, a material with excellent optical properties. This allows the cells to contain the sample being analyzed and to be illuminated by light sources such as fluorescence or ultraviolet light, enabling fluorescence or other spectroscopic analyses.
High Chemical Resistance
Flow cells made from quartz material exhibit high chemical resistance, withstanding strong acids, bases, and organic solvents, ensuring stable performance in various chemical analyses.
Precise Optical Path Length Control
Quartz flow cells provide precise control over the optical path length, which is critical for spectroscopic analysis. Some flow cells can achieve path length precision of ±0.02 mm, ensuring the accuracy of measurements.
Wide Wavelength Range Applicability
Quartz flow cells are suitable for a broad wavelength range, from ultraviolet to visible and even near-infrared regions. This allows them to be used in various analytical techniques, such as UV/VIS/NIR spectroscopy.
Application Scenario
Environmental Monitoring
Quartz flow cells are used to detect the concentrations of pollutants such as organic compounds, heavy metals, and nutrients in water bodies, aiding in the assessment of environmental quality.
Biomedical Field
In biomedical research, quartz flow cells are used for the detection and quantitative analysis of various biomolecules and biological processes, making them important experimental tools in scientific research and technological applications.
Chemical Analysis
Quartz flow cells are employed for the quantitative and qualitative analysis of various chemical components and are suitable for use in spectroscopic instruments such as fluorescence spectrometers and UV-Vis spectrophotometers.
Pharmaceutical Analysis
In the pharmaceutical development process, quartz flow cells are used to study the photoelectrochemical properties of drug molecules, providing a theoretical basis for drug design.
Optical path contamination is a common issue that can affect the performance of quartz flow cells. To avoid optical path contamination, regularly flush the flow cell with ultrapure water and check that the quartz windows are clean. Also, ensure that the solvents used are pure to prevent contamination from impure solvents.
The pressure resistance of quartz flow cells depends on their design and materials. For example, some quartz flow cells are only rated to withstand pressures of up to 20 bar. Therefore, when using them, avoid excessively high pressures to prevent damage. Different detectors have flow cells with varying pressure resistances. For example, DAD/MWD detectors can typically withstand pressures up to 120 bar, while FLD detectors are limited to 20 bar.
Proper maintenance and cleaning of quartz flow cells are essential. Avoid allowing samples to dry inside the flow cell; they should be cleaned immediately after use, following the manufacturer’s cleaning instructions. Also, avoid direct contact with the measurement window to prevent contamination or scratching, which can affect the accuracy of measurements. To address potential algae growth issues, an organic solvent such as 5% acetonitrile or methanol can be added and the cell should be flushed regularly with double-distilled water.
