I recently purchased a GV to do waters and carbonates here at Georgia
Tech (a colleague of mine here purchased the same machine), and we have
had nothing but trouble with GV.
I am not replying to the listserv because I still need to work with GV
to finish the installation of the machine.
They are extremely understaffed and over-committed, and it has been a
real nightmare trying to get our machines up and running.
To make a long story short, we purchased the machines in Feb 2004, with
a promised delivery of July 2004.
The machines were delivered to Georgia Tech in April 2005, with an
install estimate of 1 month.
It is September now, and netiher machine has passed specifications and
they still cannot figure out the problem. Obviously they were shipped
prematurely because we were threatening to pull out of the deal and go

If you'd like to talk about this in the future, please feel free to
And by the way, please mention my name to your GV sales rep when you
bring up these issues with him - it might help us out for them to know
that we are spreading the word on how they failed us.
