FAQ
Q: Why is the black wall design important in the Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector?
A: The black wall absorbs stray excitation light that typically reduces signal clarity in fluorescence assays. By suppressing background noise, the cell improves signal-to-noise ratio and enhances detection sensitivity. This makes the Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector particularly effective for low-concentration fluorescence measurements.
Q: How do the M6 threaded connectors benefit fluorescence analysis applications?
A: The M6 threaded connectors ensure leak-free integration with pump systems and analytical manifolds. This stability is critical in fluorescence analysis, where inconsistent flow paths can cause data variability. With the Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector, users achieve reliable performance during continuous flow assays.
Q: Can the Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector handle high-pressure flow conditions?
A: Yes, the M6 threaded fittings are engineered to withstand up to 1.5 MPa without leakage. This makes it suitable for fluorescence assays in HPLC-linked or continuous flow systems. The Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector maintains optical stability even under demanding flow conditions.
Q: How does this flow cell improve reproducibility in fluorescence assays?
A: Clear-wall cells often introduce optical interference that lowers reproducibility in quantitative assays. The black wall eliminates much of this variability, giving more stable fluorescence signals. As a result, the Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector improves consistency across repeated measurements.
Q: How does this flow cell support trace-level fluorescence detection?
A: By eliminating stray light and maintaining a stable optical path, it lowers the detection limit for trace analytes. This is especially useful in biomarker or contaminant monitoring at very low concentrations. The Quartz Black Wall Fluorescence Flow Cell with M6 Threaded Connector is engineered for high-sensitivity assays.
