Nuc-WipesTM 可溶性環(huán)境檢測(cè)擦拭紙
- Completely Dissolving Wipes for Environmental Tests
- Greater Counting Efficiency
- Increased Reliability
- Safe and Easy to Use
Catalog Number:SG NW-300
1.用于環(huán)境檢測(cè)的完全可溶擦拭紙
2.更好的計(jì)數(shù)效率
3.提高數(shù)據(jù)可靠性
4.安全且方便使用
Nuc-Wipes可溶性環(huán)境檢測(cè)擦拭紙可以完全溶解于任何的液體閃爍溶液中，因而不會(huì)阻礙和吸收待測(cè)物發(fā)射的beta射線。它可以達(dá)到全4π的計(jì)數(shù)效率，排除了因?yàn)V紙本身吸收部分beta射線而丟失計(jì)數(shù)的可能性。使用普通完整的濾紙用于環(huán)境擦拭實(shí)驗(yàn)會(huì)得到錯(cuò)誤不穩(wěn)定的結(jié)果，濾紙上的粒子發(fā)射的beta射線由于濾紙自身的吸收和折射而減弱。而且由于測(cè)試粒子對(duì)溶液相對(duì)親和力的變化，粒子離開(kāi)濾紙進(jìn)入溶液中會(huì)使計(jì)數(shù)不斷的改變。Nuc-Wipes環(huán)境檢測(cè)擦拭紙排除了這些影響實(shí)驗(yàn)結(jié)果的因素，因?yàn)樗耆芙庥陂W爍液中，不存在任何完整的濾紙吸收和削弱beta射線，因而提供更加穩(wěn)定可靠的實(shí)驗(yàn)結(jié)果。
Nuc-Wipes are dissolvable pads which assure superior environmental wipe tests. Nuc-Wipes are completely soluble in any scintillation solution, and because Nuc-Wipes dissolve completely, no emitted beta ray can be hindered or absorbed by an undissolved portion of the wipe. Nuc-Wipes allow full 4π counting efficiencies, thereby eliminating the possibility of lost counts due to absorption of beta rays by the filter itself.
Using intact filters for environmental wipe tests can give inaccurate, erratic results. Beta rays originating from particles on intact filters are attenuated and absorbed by the filter. Furthermore, depending on the relative affinity of the material for the solution, as material leaves the filter for the solution, counts change over time.
Nuc-Wipes eliminate the dependence of results on the direction of the filter paper and time. Because Nuc- Wipes dissolve in scintillation fluid, there is no intact filter to absorb or attenuate beta emissions. 4π counting efficiency is achieved, giving reproducible results.
