The Verification Standard is a set ppm because you have weighed it and dilluted it.
The Verification Standard is measured in relation to the Internal Standard but that is an entirely different story.
Aren't there any Chemists here?

If the Atomic Absorption doesn't work try ExRay Defraction Spectrophotometry, but be sure to wear a lead suit......I never did! You may also want to clean out your deionization machine. Then take a nap.

So if I understand this, it seems that your verification standard accuracy is determined by the accuracy of your scales?

But seriously, safety equipment is a must, particularly when you work with other people.
My coworker sprayed me with Acetonitrile from the HPLC just the other day, lucky I had my safety glasses on. I had to use the chemical wash but I still have both my eyes.

Analytical Chemistry is madening, don't you agree!
I just spent many hours today trying to figure out why my Standard Verifications were turning out wrong over the past couple of days.
I have taken apart so many syringes to inspect plungers, gaskets and all! I have prepared GC vial after GC vial, checked the gases, even changed the gases! Checked s ...[text shortened]... g!
How many hours has this taken from my chess game over the past few days? Too many!

Sounds like the lab techs need a beating.
