[ RadSafe ] LSC Method Assistance Needed - CO2

[blreider at aol.com]

One of my friends, a new HP, asked me if I could assist him in finding a better cocktail for his SC work.  He writes:  "Our breath bioassay monitors 14CO2.  So we have a solution that we make, and we bubble the air from the balloons in the solution to trap the co2 and count it on our LSC.  This has been done for a long while, but the mixture is made up of some nasty stuff, so I just want to see if we can do better." 

The method they use a toluene based cocktail:  "solution that contains toluene,sodium hyrdroxide, trimethylbenzene, and methyl glycol."
It has been a long time since I did LSC so if you have any experience and advice I am sure he will appreciate it.
Thanks in advance.
