SRI H2 Gen

CT SRI GCs APPS Videos-m4


BE-A-WARE !
  MS WINdows generally has always been a “bit of a dog” since it’s initiation in the 1980s and through its various incarnations from DOS> XP> Win7(reiiable),> Win10 ( also 99% reliable ! . . . ? )
BUT WIN11 in reality (2021+) is STILL being “debugged”
by YOU “ end-users WW ” & NOT US ! ( > THE strategy (ploy) of ALL’S’ware in fact ! and by each And ANY OEM ) of ANY era )
But it’s
The best(?) THE World Can Offer ?

SRI GC PeakSimple has been “in vitro” for >~30years evolutuons THe GC ( current SRI 8610 model) and the “bult-in”PeakSimple /DataSys has been thoroughly  “debugged” progressively as a GC Operating System ( when/If used  within thestated SRI Operating Instructions )

GUARANTEED TO BE FULLY FUNCTIONAL in the hands of EndUsers with a “modicum” of technical laboratory experience
GC does need a basic understanding of the many High Technical specialties
SRI Provides the best possible trouble-shooting Help > On-line PDFs and U-tube Videos via the SRIGC.com or this www.chromtech.net.au/sri gcs-m5.htm website

NOT necessarily for “just “Moms & Pops” or “school kids”

It as a complex “kababble” of essential ongoing High Technology including >

  • computers & accociated relevant s’ware
  • electronics
  • gas pneumatics
  • chromatography experience
  • general handyman skills
  • an “ounce” of “common sense ? “

some organisations even restrict use and ANY maintenance ON ANY Instrumentation to skilled professionals with appropriate certification . . . re OH&S in particular !
-    a “general” pHD is simply NOT a suitable qualification MIN of
BSc -Chemistry is suggestted>recommended ! > & by an authenticated “approved University”

SRI / Chromalytic Technology DISCLAIMER
/ emphasized >here ! ( see Our general Disclaimer ) AND the SRIGC WARRANTY

We accepts NO Responsibility what-so-ever if the SRI GC “System” is used > “otherwise”

IN Reality this includes . . .

  • installing a computer of any sort  stand-alone or on a LAN or THE Internet
    Including ANY Security Required > Anti-virus and “sammer”protection deemed necessary !
  • Downloading or installing ANY “UNAUTHORIZED”ANY 3rd party S’,ware onto such SRI GC “Operating System”
  • To even plugging the “system; into a Live Power Point or even turning the light-ON in your Laboratory / work room
    ALL> a University pre-requistite it seems ! whether”woke” Regulations
    Or NOT !
     

SRI GCs  ( All 8610s )TO START

  • IF U Don’t Understand THEN ASK Question FIRST !
    before PURCHASE & BEFORE INSTALLATION !
  • Download HELP Info onto a separate PC ( Internet Connected )

    ANY GC TROUBLE Whatsover !
    Install PeakSimple onto a “safe” PC

    WIN10 ( but NOT necessarily !WIN11  ) using the latest appropriate PS Version  recommended  by SRI !
    WIN 10 is ((%OK} ( and more-so WIN 11 ) IS Certainly NOT “FOOLPROOF”
    THE “hassle” IS to Turn -Off the WIN AUTO Download of THEIR UPDATE ( even WE can’t reliably do This effectively > a WIN 11 “bug” )


    This in extreme circumstances CAN effect long term running of PeakSimple and the GC  . . . with some annoying shut-down(s) & spasmodic maybe under
    WIN 11 but this is very rare yntuil U prove otherwise
    ALL-At-Your-Risk !

  • BE-A-WARE !
     

NO two After PS Loaded on a Stand-alone “clean-PC”

The default Oven air circulation will certainly cope safely under normal capillary column operaton ! (1-10 m/min even with a column break BUT Do NOT Vent column Outlet into the oven during a “bake-OUT!
