Selection Guide for Liquid Scintillation Counter
Liquid Scintillation Counter is essential for accurately measuring low-energy beta emitters like tritium (³H), carbon-14 (¹⁴C), and sulfur-35 (³⁵S) in environmental, pharmaceutical, and biological research.When selecting a suitable model, key factors to consider include sample type and volume, detection sensitivity, background noise level, and the system’s ability to correct for quenching and perform dual-label counting. Models with high throughput and automatic sample changers are suitable for laboratories handling large sample loads. Advanced features like TDCR technology, spectral analysis, and user-friendly software for data acquisition and reporting enhance efficiency and accuracy. Additionally, it is important to choose equipment that meets international safety and quality standards such as ISO, CE, or RoHS certifications, especially for use in GLP/GMP-compliant settings. Reliable after-sales support, ease of maintenance, and compatibility with data management systems further contribute to seamless operation and long-term laboratory performance.
Understanding Liquid Scintillation Counter: Purpose, Process, and Benefits
Liquid Scintillation Counter is a laboratory instrument that measures radiation especially low-energy beta particles by detecting the light (scintillation) produced when radioactive isotopes interact with a scintillation cocktail. This cocktail, which contains fluor molecules, emits photons when excited by the energy from radioactive decay. These photons are detected by photomultiplier tubes, converted into electrical signals, and then analyzed by the system.
Our Scintillation Counter offers reliable, high-precision measurements where other methods fall short. Its ability to detect minute levels of radiation across a range of applications from environmental surveillance to pharmaceutical research makes it a cornerstone of any laboratory working with beta-emitting radionuclides. It features;
High Sensitivity for Low-Energy Beta Emitters
Multichannel Detection
Automatic Background Reduction
Sample Versatility
Liquid Scintillation Counter is widely used across numerous scientific and industrial fields for detecting low-energy beta radiation. In environmental monitoring, they are essential for detecting trace levels of beta-emitting radionuclides like tritium, carbon-14, and strontium-90 in water, soil, and air samples to support pollution assessment and regulatory compliance. In pharmaceutical and biomedical research, they play a crucial role in radiolabeling studies, metabolic pathway tracing, pharmacokinetics, and bioavailability testing of radioactive isotopes. Molecular biology and life science laboratories use Liquid Scintillation Counter to measure radioactivity in DNA/RNA labeling, enzyme activity assays, and receptor-binding studies.
