SV: Re: Real-time mold analysis

[Guest guest]

Interesting !

Do you have any more info on this Mr. Shane ?

There is also the Burkard 9100 sampler that samples air and deposit

the spores /fragments / dustparticles on a slow-moving, coated glass-slide…

 

It is of cours not " real-time " , and you need a good

microscopist, but at least you can detect the variation in a time-serie (up to 6-12

hours )

There are indeed real-time pollen and mold counting

machines. To my knowledge, a Japan group is the most advanced. However, these

are not very good and do not count everything because they use fluorescent

taggants and many of the fungal spores do not bind with the taggant. This is a

long way of saying that whoever told you there was a real-time mold counter was

clearly not talking about something that identifiied the actual mold.

Probably particle counter as you supposed.

MycoMeter does have a device that provides a general qualification of the

amount of total fungal debris in air samples. If this works like their original

MycoMeter samples, then results can be given in 15 minutes or so. The MycoMeter

works on a relative scale, but doesn't give actual counts.

I would really hesitate using air samples or even particle samples unless they

are collected during several rounds, as any single sampling ponint may

drastically vary from the next.

There are standards for duct cleaning that include a visual assessment and

quantifying surface dust amounts. Email me if you want more info on these

standards.

Personally, I do a visual assessment followed by a few surface tape samples to

ensure fungal debris (if it was present) was sufficently removed.

Ole,There are several (including more than one type of Burkard) slit samplers that sample continuously, but you are right, they are real time.The paper I was referring to came out a numbrer of years ago. I will see if I can find my copy. If I find it I will certainly send it to you. It had color plates.As I recall, there was also a Harvard-developed machine that was trying to do the same thing, but nothing was published to my knowledge.Sorry for being so vague. It has been a long time since I have thought about these issue because they simply don't work well.john
