Ohhhhhhhhhh...I thought NP = not possible!!! You can laugh at me...it was a long day...
But as I said, regardless of whether the method specs a particular SOP, the instrument and operator can still have a "bad day"...you cannot base the efficiency on a single sample. I would be interested to see a second and third sample (and I hope they are just as good), but until all human error is removed, one sample doesn't really say much to me.
And just so you understand where I'm coming from, I have personally collected, submitted for analysis, and then scrutinized the results for more than 500,000 samples (and that's a single job).
You would be amazed at the kind of problems a lab can have and the amount of garbage data they will put on paper. And they have a lot higher accreditations to achieve than our UOA labs probably do...just food for thought, it happens.
