As is with John in the
picture, your first thought
might be “I think I need
RSA Glass,” after learning
how common autosampler
vials can be the source of
your sample problems and
nonreproducing
results. The
presence of “silanols,” metals,
and common contaminants
found on the surface of borosilicate glass vials can absorb
basic compounds and cause hysteresis with pH changes. RSA™
has virtually no silanols or metals and is contaminant free,
eliminating common vial problems at the same cost as ordinary
vials and caps. These vials will meet or exceed the most expensive
“Certified Vials” and do not suffer from “delamination” as
with ordinary vials. www.mtc-usa.com/rsa_glass.asp
