1. 适合于环境样品的测定

2. 超高的水容量(闪烁液样品比达到1:1.2)

3. 的背景噪音

4. 无比**的计数效率

5. 非常适合低温环境下的计数测定

ND当初打算设计Ecoscint Ultra闪烁液是为了满足环境样品测定和尿的生物测定需要，Ecoscint Ultra闪烁液优越的性能不仅成功的达到了原来的目标，还成为了**满足市场上大小体积水溶性样品测定需要的复合配方闪烁液。Ecoscint Ultra闪烁液可以从背景中区分出低水平的放射计数，不仅适用于大量的样品，也适用于小量的样品。测定大量样品时可以在饱和容量和非常低的背景下保证30%的 3 H计数效率。小量样品则可以达到60%以上的 3 H计数效率。在18摄氏度时10毫升的闪烁液可以容纳12毫升的水溶液样品形成透明的乳化液。在同样的温度下10ml的闪烁液也可以容纳10ml含0.5M NaCI的样品。

When National Diagnostics laboratories set out to create Ecoscint Ultra, our aim was to create the best cocktail available for environmental sample counting and urine bioassay. We are proud to announce that not only have we succeeded in this goal, we have surpassed it, creating the best all-around performing cocktail on the market for both large and small aqueous samples.

Ecoscint Ultra enables ultra-low level counts to be discriminated from background not only for large but also for small samples. With large samples, Ecoscint Ultra delivers up to 30% 3H counting efficiency at maximum sample hold with very low background levels. With small samples, Ecoscint Ultra yields 3H efficiency greater than 60%.

10ml Ecoscint Ultra holds 12ml H2O or 10ml 0.5M NaCl in a clear emulsion at 18°C.
