PROBLEMS WITH TURBO MOLECULAR PUMP OF SHIMADZU GCMS-QP2010
http://www.sepsci.com/chromforum/viewtopic.php?p=38774
We are users of a SHIMADZU GCMS-QP2010, since we bought it we have a
lot of problems: the ion source are dirty without a reason, repetitive
leaks that we can solve, the “gain” changes suddenly, tuning problems
(appears the message “Mass number calibration error”), software
problems and a lot of combipal syringes are doubled. The last
breakdown had been the fault of a turbo molecular pump.
We would contact with other SHIMADZU users because we would know if
they have had problems with this equipment, especially breakdowns of
turbo molecular pumps.

Dear Cristina.
We have a QP2010 too.
The turbo pump number 1( because it has two) Just failed last week
after four years of use .....and yours?.
I usually perform autotunig with a DB or HP 30m x 0.25 x 0.25 and
results good. To do autotuning with a wide bore or megabore column is
run in trouble because there isnt enough vacuum level.

It's been what, 10 years, since Shimadzu fired his sorry ass,
and yet he keeps up his campaign against them.
No wonder he's totally unemployable. Any company
would be insane to hire a raving lunatic like him. |
