LSC in a Nutshell
Essential insights into Liquid Scintillation Counting.
What is Liquid Scintillation Counting?
LSC is a standard laboratory technique for detecting β- or α- isotopes, such as 3H, 14C, 90Sr and 222Rn found in nature by human activity or naturally or used as labels in research. It involves dissolving a sample into a liquid "cocktail" containing a scintillator, which converts nuclear emissions into light photons that can be quantified.
Why is Vial Selection & Cocktail Mixing Important?
Proper sample preparation is critical. The choice of vial (glass vs. plastic) and the right cocktail for your specific sample matrix directly impacts counting efficiency and background levels. There are number of factors that need to take account to avoid interference in your data. These include temperature, sample-to-cocktail ratio, chemiluminescence, color, ions, etc.
What is TDCR (Triple-to-Double Coincidence Ratio)?
TDCR is an advanced absolute activity measurement method used in modern counters like Hidex 300 SL, 600 SLe and ULLA. Unlike methods based on External standards, the method utilizes the physical properties of the measurement system itself (three detectors) to calculate the ratio of triple and double coincidences (TDCR), correlating directly to counting efficiency. This allows for direct determination of absolute activity DPM.
Optimization & Calibration
Optimizing LSC involves precise background and efficiency calibration using optimized instrument parameters and conditions. Understanding these parameters ensures your data is not just numbers, but accurate scientific evidence.
