Design life of an Agilent 1100 in injection cycles-estimate

[pirish]

Based on experience, does anyone have an estimate of the design life of an Agilent 1100 HPLC system? I have one that has been 'refurbished' several times, and I'm holding it together with bailing wire and a prayer. I'm sure this instrument is well past its design life, but need some numbers to go chasing capital.

Cheers,

All our 1100 autosamplers are still going strong, pretty reliable. Our 1050 autosamplers are also still working.

Design life may have some impact from maintenance activities.
Over 90% of our 1100s have held up and have had annual maintenance activities performed each year.

Most of the parts that fail on the 1100 are designed to be easily replaced. These include:
Needle/seat
rotor Seals
Inlet and outlet valve
Pump seals
teflon filter in purge valive
lamps
metering seal in autosampler
saphire pistons if scratched or broken
MCGV (gradient mixing valve)
gold seals

Anything else can be sent to Agilent for I believe around a $2k flat rate repair. I had to send a pump to them for replacement of the pulse dampener and obsolete main board that was causing baseline issues.

Basically I do almost all my own maintenance except for the above rare/ problems and they hold up fine.
