Fermi chem lab response - Fermi does not use quench curves, we distill all water samples and count a matrix matched standard with each sample set to calculate efficiency.

We do not prepare our own quench sets. We looked at this many years ago, and the Chemical Use Review Board (CRUB) has a serious issue with using nitromethane. Due to its toxicity and volatility, we opted not to buy it. Kenneth Walter RP Technical Advisor, Radiological Engineering P.O.

If you do use it, can you tell where you purchase the chemical from, concentration, catalog number, and what quantities you use for quenching your standards?
