Re: Re: does this sound correct?

No - sorry to give that misimpression. You'd need a professional anyway for the

lab work that goes with the testing and the whole chain of custody thing, but

very few professionals have it anyway. My point was only that the service she's

looking at sounds like it doesn't cover very much at all and the only machine

I'm aware of that can do that much with so little effort is the Omni 3000. That

price would probably be a value for its use, but I haven't heard of anyone

getting access like that.

Is high-volume mycotoxin sampling of air being done outside of the

laboratory? It really, really should be.

Impingement samplers left running over long periods of time are about as

close to a human lung situation as you are ever going to get. With

mycotoxins as powerful as they are, you need long periods of sampling to

capture amounts large enough to detect. Kind of like a person breathing for

hours in a day, or hours in many days for weeks or months or years.. (as if

they lived or worked in the sick building)

Mycotoxin testing of bulk samples is much more feasible for most people

because you don't need those high volume pumps running for many hours or

days..

When they do spore testing, they just sample a few cubic meters of air,

catching the particles above the filter size. Many smaller spores just slip

through. Then they look at that under a microscope and count spores. All

aspergillus penicillium type are lumped together, but many smaller asp/pen

spores and many more particles just slip through and particles by definition

cant be identified.

Quack - you generally retain this sort of data better than I do, but what I

learned about the hallowed Omni 3000 is that in 10 minutes, it is doing roughly

30 days worth of 'breathing' the air it's sampling...(those are the numbers I

recall - I hope it isn't just 30 hours - lol), but that's what makes this

machine so very special.

PS - I owe you a call...haven't forgotten.

I don't know of anyone who is currently doing the kind of testing for end

users like us that Texas Tech was doing.
