I am facing a problem in ATP bioluminescence.
After washing a surface, the ATP decrease. Then the same surface is sanitized by alcohol and ATP increase after sanitation instead of decreasing!!
Any hypothesis ?!
Hello,
Very interesting issue.
Did you check your your ATP analyzer ? Are you sure it works properly ?
How do you clean the surface ?
Which chemicals do you use ? only alcohol ?
Is the surface smooth or rough ? What is it ? A table, a belt or ?
Any comment please Mr. @gokhan.durmaz
Yes, I checked the analyzer and its working properly.
The surface is first washed then sanitized only by alcohol (isopropyl).
I have done this on many surfaces (table, chair, and even on my hand)
Hello,
as far as i can understand your alcohol contains dna somehow. Even if it kills bacteria i do not think that it decomposes dna. Just the dna is precipitated with IPA. So i can recommend to change alcohol with a purer one or you may distillate before use.
