PROBLEMS WITH TURBO MOLECULAR PUMP OF ****MADZU GCMS-QP2010
http://www.sepsci.com/chromforum/viewtopic.php?p=38774
We are users of a ****MADZU 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 ****MADZU 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.
